What is Distillation? Principles and Applications

Distillation is a technique for the separation of mixtures based on differences in the conditions necessary to alter the phase of components in the mixture. This is a widely used technique in which mixtures of liquids are heated to mean components which have different boiling points into the gas phase. This gas is then condensed and cooled.

Rotary evaporators provide a means of reduced pressure distillation, where the residue is retained rather than the distillate.

Applications of Distillation

Distillation is used for a number of applications such as distilled water, kerosene, gasoline, and many other liquids. Gases may also be liquified and separated, such as nitrogen, oxygen and argon which are distilled from air.

Water from natural sources contains a broad range of minerals and other impurities, many of which are removed via distillation. Distilled water is often used when the presence of minerals could impact the effectiveness of equipment, including in steam irons.

Distillation is a part of the production process of a range of alcoholic beverages such as brandy, whiskey and rum. When plant and fruit materials ferment, ethyl alcohol in a dilute form is produced, distillation is used to purify and concentrate the ethanol.

Distillation of crude oil can produce a range of products, as each of these products has a unique boiling point. A process known as fractional distillation is used to refine oil into a range of materials.

However, distillation alone cannot remove all unwanted lipids such as fats and waxes from oil extracts. This has an impact on the quality of the end-product, leading to a reduction in potency and clarity. Rotary evaporators can be employed to winterize oils and enhance their overall quality.

Using Rotary Evaporators in Distillation Applications

Rotary evaporators are becoming more widely used for distillation applications. Distillation via rotary evaporator is faster than traditional methods as solutions are distilled under reduced pressure at a lower temperature, speeding up the process because of the larger surface area.

Using a rotary evaporator for distillation also saves space in the lab as one piece of equipment can be used for multiple applications.

Rotary evaporators also save energy over traditional distillation methods, as they do not need to heat the mixture to such high temperatures. This also reduces the degradation of temperature-sensitive components which could adversely impact the reaction.

Ethanol Removal in Cannabis Applications

Extracting cannabinoids and other compounds from raw cannabis can be done using a range of techniques. The most popular techniques are extraction using CO2, ethanol or a hydrocarbon such as butane. The selection of one of these techniques is based on a range of factors such as the final application of the product (such as what form it will take and whether its for recreational or medicinal use). It is also important to know the amount of raw material to be processed.

This article will focus on the method of ethanol extraction which can be done in a range of methods such as warm, cold or room-temperature processing. Lots of ethanol extraction processes require the use of a rotary evaporator to remove the ethanol from the extract solution.

This article will examine the method of ethanol extraction for cannabis applications, particularly focusing on ethanol removal with the use of a rotary evaporator.

How Ethanol Extraction Methods are Used for Cannabis Applications

There are three main methods of ethanol extraction which are:

Cold Process – this is when the cannabis plant is soaked in ethanol which has been chilled, stopping undesirable compounds such as waxes and pigments from turning to solids, however, it also means the extraction of desired compounds is slower.

Room Temperature Process – similar to the cold process, room temperature ethanol extraction involves raw cannabis being soaked in ethanol at room temperature to pull out soluble compounds. The cannabis is then removed and the solvent is evaporated.

Hot Process – this process involves using hot ethanol to solubilize compounds and requires the use of specialist equipment. This ethanol removal method is difficult to scale up and can lead to undesirable compounds ending up in the solvent.

Ethanol removal is popular for several reasons. It can extract a large range of compounds from cannabis plants, as well as the process being refined to stop certain compounds from solubilizing. It can also be scaled so it’s suitable for processing extremely large volumes of cannabis.

A Brief Guide to Ethanol Removal

Step 1: the plant is soaked in ethanol, causing certain compounds inside the plant to solubilize with the specific compounds extracted being dependent on the temperature of the ethanol and the makeup of the plant.

Step 2: After a sufficient amount of time the plant is removed from the mixture.

Step 3: The next step is the winterization process, which involves more ethanol followed by rapid cooling to remove lipids.

Step 4: the solvent must be removed for the solution, typically using a rotary evaporator.

Step 5: High purity cannabis oil remains, often with some residual solvent. This is removed by drying the oil in a vacuum oven.

Rotary Evaporators for Ethanol Removal

Rotary evaporators are extremely efficient in the removal of volatile solvents from non-volatile samples. Rotovaps decrease the solvent’s boiling point, minimizing exposure to heat, which is particularly important for temperature-sensitive compounds. Rotovaps are also environmentally friendly and have excellent repeatability.

At Ecodyst, we supply a range of innovative, eco-friendly, and simple-to-use rotary evaporators for ethanol removal of any size as well as other solvent recovery. To find out more, contact us today.

The Modern Rotary Evaporators: Ecochyll X1 and Hydrogen

Rotary evaporators, also known as rotovaps, are a common sight in most chemistry labs. Perhaps surprisingly, this familiar piece of equipment hasn’t changed much since it was first invented in the 1950s. Even though new models of rotary evaporators are developed each year by major manufacturers, the basic principles of operation have remained the same. Until now, that is. In this article, we take a look at how Ecodyst is revolutionizing the world of rotary evaporators; eliminating costly consumables while offering better performance, simpler operation and drastic reductions in lifetime costs.

Rotary Evaporators 101

The first rotary evaporation system in scientific literature was described in 1957 by researchers at the Rockefeller Institute for Medical Research in New York.1 These researchers placed a dilute solution in a round-bottomed flask over a heat source. This flask was connected to another round-bottomed flask, which was partially submerged in an ice bath. The two connected flasks were then evacuated using a vacuum pump and rotated about their axes for even heating and cooling.

Original schematic for a rotary evaporator (Anal. Chem. 22, 1462–1462 (1950))


By evenly heating the flask containing the dilute solution at reduced pressure, the researchers could easily evaporate the solvent from the solution, which was then condensed in the cooled glass condenser. This yielded a concentrated solution in the heated flask.

Early improvements to this original design included the use of a hot water bath rather than a burner, and the insertion of various traps between the evaporation flask and the condenser. It wasn’t long before the first commercial models were produced. Today, rotary evaporators are used at all scales, from benchtop research models (typically 1 L capacity) to larger models for pilot plants and commercial syntheses with capacities of hundreds of liters. New rotovap models often feature vapor temperature sensing and digital controls for vacuum pressure, temperature and rotational speed.

However, despite incremental changes over the last 60 years, the basic operating principles in today’s conventional rotary evaporators remain the same as they ever were.

Limitations of Conventional Rotary Evaporators

Despite their widespread use, conventional rotary evaporators suffer from some serious drawbacks, most of which can be attributed to the use of glass condensers.

Glass has traditionally been used in chemistry applications due to its low cost and resistance to most chemicals – these properties alone have made it the material of choice for the condensers in virtually all rotary evaporators. However, glass is far from ideal for this purpose: glass is a poor conductor of heat, so conventional rotary evaporators need to work harder to overcome the poor rate of heat exchange through glass condensers.

Other issues with conventional rotary evaporators include high operational costs, inefficient vapor trapping and time-consuming management of dry ice and solvent mixtures.

Revolutionizing the Rotary Evaporator

Ecodyst sought to overcome the limitations of conventional rotary condensers by rethinking several elements of its design, starting with the condenser. At the heart of an Ecodyst rotovap is a metal condenser coil coated with special chemical-resistant polymers. While simple, this change represents a paradigm shift in rotovap design and produces a number of significant advantages over traditional glass condensers.2

The metal condenser, featured in Ecodyst’s Ecochyll X1 condenser, not only offers much better thermal conductivity (and therefore more energy-efficient cooling) than glass, but is also highly durable and has a huge surface area, which allows for customization.

Crucially, the metal condenser is also strong enough to be connected directly to a pressurized refrigeration system. This means that the recirculating chiller needed glycol or water systems can be completely eliminated, saving maintenance and hardware costs as well as drastically reducing the amount of space taken up by the rotovap system.

A completely self-contained coolant circuit means that operating costs are drastically reduced compared to any other type of rotovap setup: the Ecochyll X1 means no need for dry ice, coolant or water. The only operating cost is the cost of the electricity required to power the device; which, thanks to its more efficient design, is around 50% of that required for a conventional glass condenser rotovap. Thanks to these substantial savings, the Ecochyll X1 typically pays for itself within 3-5 years of average use.

Ecodyst cooling technology not only offers cheaper and more efficient operation than competing systems, but also better performance: the efficient condenser reaches  in under a minute (compared to 45 minutes for conventional recirculating chillers) and offers much faster rates of evaporation than traditional rotovaps.


Ecodyst Rotovap Systems for the Lab

Ecodyst produces two benchtop systems for rotary evaporation: the Ecochyll X1 and the Hydrogen.

The Ecochyll X1 is a benchtop cooler/condenser engineered for best-in-class evaporation in lab environments where space is at a premium. Thanks to proprietary smart cooling technology, the Ecochyll X1 sets a new benchmark for reliability and efficiency.

The Hydrogen packs the same condenser technology into an all-in-one rotovap. Combining rotary evaporator and condenser into a single benchtop unit provides the same high performance as other Ecodyst products in a simple-to-use format with a footprint of only 1.8 square feet. Inbuilt digital controls offer precise management of all system parameters, while a remote function enables full PC control and data transfer for further processing.

Ecodyst now offers a full range of rotary evaporators, from 1L benchtop models like the Ecochyll X1 and Hydrogen through to the 200L Ecochyll X9 for process chemistry and commercial applications. Ecodyst’s unique cooling technology enables researchers and industrial chemists alike to move on from expensive and time-consuming management of dry ice and coolant systems, and reap the benefits of high-performance and low-cost extraction.

Winterization of Oils to Remove Fats and Waxes

Cannabis and hemp are botanically complex, containing a rich assortment of carbohydrates, insoluble fibres, proteins, chemicals, and vitamins. Among the most valuable constituents of the Cannabis sativa and indica plant species are—of course—cannabinoids like cannabidiol (CBD) and tetrahydrocannabinol (THC). Extracting these compounds from the raw plant material and purifying it into a high-purity end-product requires a multi-step workflow, from harvesting through to winterization.

Why Winterize Oils?

Fractional distillation alone will often fail to remove unwanted lipids like fats and waxes from oil extracts. This can have a direct effect on the end-product, diluting potency, reducing clarity, and generally leading to a distillate of overall reduced quality.

Winterization is key step in the extraction and purification of oils derived from cannabis and hemp. It involves the fractional crystallization of the extract using butane or high proof ethanol at cryogenic temperatures, or liquid carbon dioxide (CO2). Cold ethanol winterization is usually preferred as it is relatively inexpensive and quick, but it tends to produce darker extracts. We compared the impact of different extraction methods in a recent article: What is the Winterization Process?

In cold ethanol winterization, the raw, unfiltered extract is mixed in the alcohol solution until fully combined then cooled to temperatures approaching -80°C. Critical winterization parameters include cooling rate, temperature of crystallization, and molecular mobility within the oil mass, as these variables directly influence the precipitation of solid fats and waxes.


Once winterization of oils and fats is complete, the heterogeneous crude mixture can then be filtered using traditional filteration equipment. It may also be decarboxylated to convert cannabidiolic acid (CBDA) into CBD, producing higher concentration extracts. The filtrate is concentrated down to separate the ethanol from the cannabinoid oil; a term often referred to as post-winterization

Post-Winterization Equipment

The type of equipment used in post-winterization depend on the method used. Both sub- and supercritical CO2 extraction typically use falling film evaporators, but such a bulky and large-scale apparatus is unsuitable for modern cannabis facilities.

Cannabis today represents a booming global industry contributing billions of dollars to economies around the world. Producers looking to drive the bottom line and increase profit margins without compromising the quality of their product offering must be able to distil and purify large volumes of oil quickly and effectively. The falling film evaporator is unfortunately unsuitable for such an initiative, particularly for small-scale laboratories looking to produce high-quality cannabinoid oils on a budget.

At Ecodyst, we have pioneered a new extraction and platform based on a proprietary cooling technology that maximises yields, quality, and time. If you would like to learn more about how our evaporators are used in post-winterization processes, why not contact a member of the team today?

Exploring the Drawbacks of a Falling Film Evaporator

Typically, evaporation is carried out within vertical tubes. However, in some applications, process fluid evaporates outside horizontal or vertical tubes. The process fluid will always evaporate downwards due to the effect of gravity as a continuous film, creating a film along the tube walls and falling downwards. A fluid distributor is created to maintain an even liquid distribution for every tube that the solution falls down.

Falling film evaporators are widely used as an evaporation technique, however, they can be inefficient. This blog will explore the drawbacks of these evaporators, comparing them with rotary evaporators.

How do Falling Film Evaporators Work?

In most applications, the heating medium is on the outside of the tubes. High heat transfer coefficients are necessary to accomplish equally balanced heat transfer resistances. As such, the most commonly used heating medium is condensing steam.

When fluids are internally evaporating, separation across the liquid phase (the solution) and the gaseous phase happens within the tubes. To uphold conservation of mass as this falls, the downward vapor velocity rises and this increases the force acting on the liquid film and thus the velocity of the solution.

On the evaporating side of the tube, the heat transfer coefficient is often subject to the hydrodynamic flow conditions of the film.

Unfortunately, the inner wall of the heat exchange tube of the falling film evaporators must be entirely wet and the membrane is not too thick. It is important to implement a precise design calculation of the material feed and the length of the heat exchange tube in order to meet the requirements.

Additionally, the cost of falling film evaporators are extremely high as there are high design and manufacturing requirements. The rotary evaporator from Ecodyst does not use expensive rotary evaporator mechanisms, meaning they are an extremely cost-effective method of evaporation.

Falling film evaporators should also not be used for materials that are prone to fouling or are made up of solid suspended matter. Conversely, the rotary evaporator from Ecodyst can efficiently and gently remove solvents a broad range of sample types, this includes both organic and inorganic analytes as well as polymeric materials.

Falling film evaporators are often used in heat-sensitive products such as milk, fruit juice and pharmaceuticals as the time inside the heated tubes is very low and the materials are unlikely to spoil. Rotary evaporators also work well for these types of materials as samples are heated whilst the boiling points are decreased using a vacuum which is induced by the lab rotary evaporator. The boiling point decreases as the pressure of the liquid is decreased, and the solvent can be vaporized at a lower temperature than the standard boiling point.

Falling film evaporators are also extremely large, requiring a high headroom and meaning that labs need to mindful of how to accommodate them. As the Ecochyll from Ecodyst combines the chiller within the equipment, it has a much smaller footprint and can be used in even small-scale laboratories.

What is the Winterization Process?

Winterization refers to a step in the processing of hemp into a consumer level product. It is one of the most important steps for the creation of a clean product. Winterization extracts elements which are unwanted from hemp such as waxes, fats and lipids. The elements can become cloudy, darker and have an unpleasant taste if winterization does not take place.

How Does Winterization Work?

Winterization begins with a raw extract of crude oil. This is made up of all the crucial elements of the hemp plant, excluding only the plant material. Minor cannabinoids, THC/CBD, terpenes, fats, lipids and waxes all make up this liquid and crude oil extracted by a CO2 machine is light in color, compared to oil which is extracted by alcohol and has a dark appearance.

Crude oil is then added to 200 proof alcohol and is thoroughly stirred until it is totally combined. The alcohol then thins the crude oil and parts of the crude oil remain in the solution and undesirable elements coagulate and freeze meaning they can be filtered out. The mixture will look cloudy ready for filtration.

Following this, the mixture will be strained through paper filters which will remove frozen fats, lipids and waves whilst the THC/CBD oil stays inside the alcohol solution. Filters should catch all of the frozen plant waxes when properly winterized, the filters and waxes can then be discarded and the clean oil is refrozen to go through the process again and ensure that it is 100% clean.

When the undesirable elements have been removed the alcohol is then removed using a rotary evaporator.

What are the Benefits of Winterization

Winterization is a critical step in the creation of a high purity extract. Fats and lipids dilute cannabinoid fraction and lower the purity levels. The presence of fats can also mean that the distillate is less transparent which decreases its value and can cause poor taste.

Types of Extraction and the Impact of Winterization

Cold ethanol is the optimum extraction method for minimizing fats in extract. Less fat will be pulled from the plant the more cold it is. BHO extraction will pick up a moderate amount of fats and the cloudiness will increase. CO2 extraction will pull the highest amount of fats from a plant.

The best practice is to use 10 liters of ethanol for each liter of crude extract. 190 proof ethanol is usually better than pure ethanol as it is cheaper and has 5% water which means it is more polar. This is well-suited for winterization as cannabinoids are soluble at cold temperatures whereas the waxes are not.

Ecodyst® has pioneered table-top and industrial-scale high-speed evaporators which are used in laboratory and commercial settings. Using a disruptive refrigerated cooling technology, our evaporators offer eco-friendly and effective self-cooling metal or Teflon-coated condensers that create new standards for winterization.

A Brief Guide to Cannabis Decarboxylation

Cannabis and hemp have been illegal across many parts of the world for many years, however in recent years the legalities have been gradually changing across the globe. Wholesale legislative changes have taken place in the USA and Canada, shifting an illicit, illegal market into a legitimate, multi-billion dollar industry.

Products which are based on cannabinoid extractions are increasing in value significantly. CBD oil in particular is finding popularity as a medicinal and therapeutic product and one of the key areas of debate in the sale of CBD products is that of virgin versus decarb CBD oil.

What is Decarboxylation?

Decarboxylation is a critical process in cannabis production and consumption. It occurs when cannabis is cured, allowing the THCA (Tetrachydrocannabinolic Acid) or CBDA (Cannabidolic Acid) inside cannabis buds to be converted to THC (Tetrahydrocannabinol) or CBD (cannabidol). This process is a chemical reaction which removes a carboxyl group with heat or chemicals.

The Process of Decarboxylation

Traditionally, solvent recovery and decarboxylation systems are complicated, modular setups which are made up of a number of interconnected instruments. Decarboxylation traditionally needs a large reactor with a chiller, another chiller for the condenser, and a vacuum pump. This is to decarboxylate over long periods of around 8-10 hours.

Other decarboxylation equipment such as vacuum ovens take even longer, between 14 and 24 hours and has a limited capacity. These setups are both large, taking up greater space in workplaces and are expensive, requiring intervention from users to ensure the greatest results are yielded.

Decarboxylation systems which have a reactor and chiller take a long time due to the use of thermal fluid to heat extracts to the correct decarb temperature. Using this method takes a long time as it leads to inefficient heat transfer and heat loss.

Decarboxylation Solutions from Ecodyst

At Ecodyst, we are experts in organic chemistry and have created a new evaporation system which can be used in both solvent recovery and decarboxylation. Our software uses direct-cooling technology in conjunction with continuous feeds to preserve vacuum conditions across the entire extraction process. Our EcoChyll® range out performs traditional decarboxylation systems in many ways.

Not only are decarboxylation solutions from Ecodyst cheaper than the traditional solutions, but the EcoChyll® line is able to decarb comparable amounts of cannabis oils in less than two hours. This is largely due to the efficient heating mantle design that can get to optimal decarboxylation temperatures in a few minutes whilst keeping a steady heat.

This heating mantle means that our actual volume evaporators and the EcoChyll® intelligent self-cooling technology only need a single action to start continuous decarboxylation of large amounts of sample materials at extraordinary scales.

Ecodyst offers evaporation systems appropriate for all levels of cannabis decarboxylation. If you would like to find out more about our products, contact us today.
