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.

Evaporation and Concentration

In 1957, BUCHI introduced the first commercial rotary evaporator. They have since developed the Rotavapor into an intelligent, integrated system. BUCHI's solutions cater to research, development, and production with customizable benchtop and industrial rotary evaporators, including various condensers, vacuum pumps, controllers, and chillers.

R&D is fundamental to any food and beverage processor's business. Developing new and improved products, meeting dynamic market demands, and getting to market quickly are keys to success. BUCHI sample preparation and purification products are designed to make your R&D role more efficient, productive, and automated.

Food and beverage R&D workflows require various steps of solvent and water removal, purification of natural or synthetic mixtures, and the isolation of target products. Final analysis is a critical step that depends on proper sample preparation and handling. Explore a range of BUCHI solutions to meet your workflow needs for intermediate and final product sample preparation.

Freeze Drying

Freeze drying gently preserves food without altering appearance or taste, maintaining volatile compounds and extending shelf life. BUCHI, a leader in laboratory evaporation, offers the first freeze dryer with continuous sublimation and quick method programming. Infinite-Technology™ uses two alternating condensers for uninterrupted operation.

Environmental

image7

A clean and safe environment is a prerequisite for health and quality of life. BUCHI contributes to improving the environment by providing market-leading solutions for sample preparation and solvent recovery to a wide range of industrial companies, environmental testing labs, consultants, and government authorities.

Samples from air, soil, sediment, sludge, waste, and wastewater are challenging to analyze. BUCHI offers solutions designed for quick, efficient, and reliable sample preparation for the assessment of environmental pollution. Compliance is also key, and these products will help you meet EPA, AOAC, ISO, and other regulatory methods.

Freeze Drying

Effective sample preparation is crucial for reproducible and accurate results. Residual water and solvents can hinder extraction and analysis. BUCHI Lyovapor™ freeze dryers can dry multiple samples simultaneously and monitor them to ensure protection. Freeze-dried samples are stable for processing, testing, or storage.
