Cannabis and hemp laws are slowly loosening around the world after decades of prohibition. In just a few years, wholesale legislative reforms in Canada and the United States have converted an illegal market into a multibillion-dollar legal economy. Cannabinoid-based products, particularly cannabidiol (CBD) oils, have become high-value commodities. Alaqua is processing equipment including evaporators supplier worldwide based in the US.

The cannabis and hemp industries are evolving at a breakneck pace, with producers and retailers alike competing for a competitive edge in an already crowded market. Raw vs. decarbed CBD oil is one of the most important distinctions in the sale of CBD products.

Decarboxylation is a natural part of the cannabis-consuming process. It discusses particular procedures for extracting desirable natural chemicals from plants in laboratory settings. This post will go over the process of decarbing cannabis in greater detail, as well as provide some advice on how to choose the best decarboxylation system.


What is Decarboxylation?

The transformation of CBDA (Cannabidiolic Acid) or THCA (tetrahydrocannabinolic acid) into THC (tetrahydrocannabinol) or CBD (cannabidiol) via heating and drying is referred to as decarboxylation in the cannabis extraction process. In scientific terminology, decarboxylation is a chemical reaction that involves the removal of a carboxyl group using heat and/or chemicals.

Instruments for Conventional Decarboxylation

Traditional decarboxylation and solvent recovery systems are complex, modular systems made up of several interconnected instruments. Decarboxylation alone necessitates a large reactor with a chiller, a condenser chiller, and a vacuum pump. As a result, consumers can decarb cannabis for extended lengths of time (8-10 hours).

Other decarbing equipment, such as vacuum ovens, can take much longer (14-24 hours) and have a restricted capacity. These setups are costly, and they generally necessitate regular operator engagement in order to produce the highest value results.

Due to heat loss and inadequate heat transmission, reactor/chiller decarb systems require a long time to decarb since they use thermal fluid to heat the extract to the appropriate decarb temperature (250 °F or 121 °C).

Evaporators with Cutting-Edge Decarb

Evaporation technology for decarboxylation and solvent recovery beats conventional decarb systems on nearly every front, thanks to ground-breaking direct-cooling technology and continuous feeds to maintain vacuum conditions during extraction procedures.

They can decarb equivalent volumes of cannabis oils in just under 2 hours and offer consistently higher returns on investment in practically every regard. This is made feasible by an efficient heating mantle design that quickly reaches optimal decarb temperatures and maintains heat. With an efficient heating mantle, actual volume evaporators, and the world’s most efficient intelligent self-cooling technology, continuous decarboxylation of large volumes of sample materials at unprecedented scales may be initiated with a single operation.

Rotary Evaporators For Lab

Lyman C. Craig, a scientist from the United States, could not have predicted the impact of his invention when it was first introduced in 1950. Rotary evaporators are still used in most modern chemistry laboratories more than 60 years later to meet the needs of scientists all around the world.

Rotovaps are used for fast distillation of mixed solvents, efficient drying of samples, faster freeze-drying sample preparation, chemical synthesis under reflux, natural compound extraction, and concentration due to the wide range of condensers available.

Many research and development applications include evaporation as a stage. Organic synthesis and the extraction of inorganic contaminants both need the concentration of solutions by distilling the solvent and removing low and higher-boiling or solid residue. The chemical, pharmaceutical, petrochemical, and food sectors all employ evaporators outside of research labs.

Working Principle Of Rotary Evaporator

A motor unit, a heated fluid bath, a vacuum system, a vapor duct, a condenser with either a coil passing coolant or a ‘cold finger,’ a condensate-collecting flask, and a mechanical or motorized mechanism are the main components of a rotary evaporator. The evaporation vial or flask containing the user’s sample rotates in a rotary evaporator. The axis for sample rotation is the vapor duct, which is a vacuum-tight conduit for the vapor being drawn off the sample.

The evaporator system‘s pressure is significantly reduced by the vacuum system. A water aspirator with a trap immersed in a cold bath for non-toxic solvents can be as simple as a regulated mechanical vacuum pump with a refrigerated trap, or as sophisticated as a regulated mechanical vacuum pump with a refrigerated trap. The sample is heated in a hot fluid bath (often water). Depending on the evaporation goals and any propensities that the dissolved chemicals might contribute to the mixture, the condenser utilized in rotary evaporators can be simple or complex. The distilling solvent is caught in the condensate-collecting flask, which is placed at the bottom of the condenser. The evaporation flask is swiftly removed from the heating bath thanks to a motorized mechanism.


Although evaporation is a simple process, it is not without risk. For example, implosions can occur when using glassware that has faults, and explosions can occur when concentrating unstable contaminants during evaporation. Avoid tangling loose clothing, hair, or necklaces in rotating parts.

Applications of Rotary Evaporator

The rotary evaporator has a wide range of industrial uses, including crude oil processing, cannabinoid separation, molecular cooking, flavor and aroma production, and more. Rotary evaporators can be used in a variety of industries, whether you’re in R&D or manufacturing.

Academia: In academia, solvent re-use is extremely significant. For this and many other applications, including solvent recycling, concentration, and distillation, the rotary evaporator is the best option.

Chemical: Concentration, Drying, and Solvent Recycling are just a few of the applications that an industrial Rotavapor may accomplish in the chemical industry.

Pharmaceutical: The pharmaceutical business requires an evaporation solution that may be used in a variety of situations. For gentle evaporation, the rotary evaporator is the optimum choice: concentration, drying, re-crystallization, and synthesis.
