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 […]

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 […]

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. […]

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 […]

High Quality Budget Rotary Evaporator from Ecodyst

Rotary evaporator users will know that whilst evaporation via rotary evaporator is an efficient, gentle process that can remove solvents from a wide range of sample types, the equipment can be extremely costly. Many users desire a budget rotary evaporator, however, it is important that these budget instruments do not compromise on the quality and […]

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 […]

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 […]

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 […]

5 Innovative Applications of Industrial Rotary Evaporators

Industrial rotary evaporators (also known as rotovaps) are devices which are used to gently and efficiently remove solvents from samples via evaporation. They are typically used to remove solvents from a sample of a mixture of chemical compounds. Industrial rotary evaporators use a vacuum to lower a compounds boiling point whilst the sample is heated. […]

The Basics of Continuous Evaporation Systems

What is a Continuous Evaporation System? Evaporation is a process which separates a liquid from a solid by vaporization or boiling. Evaporation concentrates a solution of a solute and a solvent, usually water, creating a more viscous liquid product. It is often used in food processing, pharmaceuticals, and chemical industries to create liquid concentrates. Evaporation […]
