BUCHI chemistry workflow solutions support many steps of your research, development, and production process. BUCHI is known to offer reliable, accurate, and easy-to-use equipment and instruments. Dependable equipment for evaporation, separation and purification, and freeze drying is critical for efficient synthesis and production. Accurate and automated melting point instruments help you analyze your samples and materials.

Complementary equipment used in the chemistry workflow allows for one supplier to support your technical and application needs: evaporate solvents from synthetic reactions, liquid extractions, filtrations, and preparative chromatography fractions; separate and purify complex reaction mixtures or extracts using flash or preparative HPLC; and use lyophilization to gently dry aqueous extractions or chromatography fractions.


From evaporation to purification to drying and final analysis, BUCHI offers the equipment and instruments you need for reproducible chemistry research.


Evaporation and Concentration

In 1957, BUCHI introduced the first commercial rotary evaporator. With technological expertise and user focus, it developed the Rotavapor into an intelligent and fully integrated system. BUCHI’s carefully conceived solutions meet various needs, whether you operate in research, development, or production. Its benchtop and industrial rotary evaporators and systems come with your choice of condensers, vacuum pumps, controllers, chillers, and other options to help you customize your solvent removal needs.

Evaporation and Drying

BUCHI SyncorePlus instruments stand apart from the rest in parallel evaporation. Advanced automation features increase productivity, and its advanced design protects the desired analyte. Along with increased analyte recovery, solvent recovery of >95% is achieved without the consumption of nitrogen. Automated evaporation with analytical precision and safety of up to 96 samples to dryness, or concentration of up to 12 samples to residual volumes, increases throughput and allows you to proceed with other tasks.

Freeze Drying

Freeze drying is a gentle form of drying and may be used to preserve foods without changing their appearance or taste. The process also avoids the loss and degradation of volatile compounds and results in a stable product with increased shelf life. As the market leader in laboratory evaporation, BUCHI offers the first laboratory freeze dryer with continuous sublimation and quick-design programming and running of methods. Infinite-Technology™ utilizes two alternately working condensers for continued operation.

Extraction and Concentration

Isolation of cannabinoids and therapeutic terpenoids typically requires the use of organic solvents for extraction or steps afterward. Industrial-scale rotary evaporators are commonly used to cover almost the entire range of solvent handling in cannabis production. Removal of the solvent is performed with careful vacuum and temperature control optimized to limit any degradation of the target cannabinoid compounds.

Cannabinoid Separation

Flash chromatography is a suitable method for the separation of different compounds of cannabis extract from each other. With this technique, it is possible to produce pure cannabinoids like CBD or THC. Flash chromatography can also be used to remove unwanted substances, such as pesticides, from the extract. The resulting products are then concentrated again using a rotary evaporator.

Rapid Analysis

Near-infrared (NIR) technology is used to develop a fast, cost-effective, and environmentally friendly method to provide quantitative data of THC and CBD content in different sources of cannabis. This analytical method is ideal for the assessment of heterogeneous material where simultaneous results of different parameters can be obtained during measurement. NIR can be used in various steps of production such as harvesting, extraction, and approving the final product.
