In vacuum applications, cold traps are devices that transform vapors into liquids or solids. The purpose of this is to stop vapors from being evacuated outside of the container, causing contamination of the equipment. Vacuum pumps remove gas molecules or air particles from a sealed volume, changing the pressure within. This article aims to explain […]

Extracting cannabis oil can be a time-consuming process that lacks energy efficiency. As the cannabis industry moves from the black market to a legal one, techniques of extraction and purification have become a focal point for researchers. Dried cannabis flower has traditionally been used for smoking and vaping, however as the industry grows, the need […]

Rotary evaporation is one of the most widely used techniques of evaporation offering excellent distillation and extraction performance. Rotary evaporation is most often used to remove a volatile substance from a liquid mixture and is carried out using a rotary evaporator. This article will outline how rotary evaporation works, some key principles, and its applications. […]

Continuous cooling is a key benefit of the Ecodyst rotary evaporator range. Rotary evaporators work to gently and efficiently remove solvents from a range of samples. Samples are heated and their boiling points are minimized concurrently using a vacuum that is induced by the rotary evaporator. The boiling point decreases as the pressure reduces and […]

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 […]

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. […]
