With laws and regulations changing and loosening all around the world, the cannabis industry is growing year upon year.

The decriminalization of cannabis for medical and recreational use is taking place in an increasing number of countries, opening the door to a brand-new market for cannabis producers.

The active ingredients in cannabis are famous for both recreational and medical purposes. Cannabinoids tetrahydrocannabinol (THC), cannabidiol (CBD) and terpenes (myrcene, linalool) have been accepted for use as treatment in various medical conditions. Hence, research into these compounds is growing as fast as the cannabis industry itself.

Safe investigation, production and quality control of the active compounds requires a diverse portfolio of scientific instruments and related application knowledge.

Processing Cannabis from Plant to Isolate

Cannabis Harvesting

The first step in cannabis processing begins with cultivation. Close attention should be paid to manage moisture levels and reduce the risk of pesticide contamination.

Sample Preparation - Milling


Cannabis Extraction

Trichomes house the cannabinoids (THC, CBD) and terpenoids. The most common methods of extraction includes supercritical CO2 or highly volatile, carbon-based solvents, including butane, propane, hexane or ethanol to isolate the active substances from the plant.

Extract Concentration

Large-scale rotary evaporators are commonly used to cover almost the entire range of solvent handling in cannabis production. Regardless of the method used for extraction, ethanol must be removed form extractions either after winterization or after the ethanol extraction step.

Cannabinoid Separation

Following extract concentration, the cannabinoids must be purified from the complex mixture. Flash chromatography is a suitable method for separation of different compounds of the cannabis extract from each other. This technique makes it possible to produce pure cannabinoids like CBD or THC.

Cannabinoid Fraction Concentration

The fractionation of cannabinoids is a step that could require hundreds of litres of solvent in the form of ethanol. With the R-220 rotavapor, large amounts of solvent can be evaporated with minimal hands-on time.
