Rotary Evaporation – R-80, R-180 & R-300
BÜCHI rotary evaporators cover routine bench-scale solvent removal through more configurable evaporation workflows. CWTC can help select the platform according to sample volume, solvent handling, vacuum, cooling and workflow requirements.
Kjeldahl Nitrogen & Protein Analysis
The BÜCHI Kjeldahl range combines digestion and distillation stages for laboratories performing nitrogen and protein determination. The product selection includes K-365 distillation and dedicated digestion units.
NIR Analysis – Portable, Laboratory & Online
BÜCHI NIR solutions cover portable measurements, routine laboratory analysis and online process monitoring. The range allows laboratories and production teams to choose the measurement location and workflow that best fits the application.
Fat Extraction & Universal Extraction
BÜCHI extraction platforms support routine fat determination and broader solvent-extraction workflows. CWTC can help select between automated fat extraction and a more flexible universal extraction platform.
Preparative & Flash Chromatography
The BÜCHI Pure range provides preparative purification solutions for laboratories working with flash chromatography and compound isolation. Essential and Excellence platforms allow the system level to be matched to purification requirements.
M-560 / M-565 – Melting & Boiling Point
BÜCHI melting point systems support routine physical-property determination for identification, incoming material checks, quality control and research applications.
Syncore Plus – Parallel Evaporation
Syncore is the BÜCHI platform for parallel evaporation, intended for laboratories that need to concentrate multiple samples efficiently within the same workflow.
S-300 – Laboratory Spray Drying
The Spray Dryer S-300 supports laboratory spray-drying workflows for formulation development, powder generation and process-development work.
Freeze Drying – Lyovapor
BÜCHI Lyovapor systems provide laboratory freeze-drying capability for samples that require low-temperature drying and controlled removal of water or other frozen solvents.
R-220 Pro – Industrial Evaporation
The Rotavapor R-220 Pro extends BÜCHI rotary evaporation into larger-scale pilot and production workflows where higher sample and solvent volumes are required.
