Published on: 13.03.2026
BUCHI Labortechnik AG has just introduced the latest model of its flash/preparative chromatography system. The history of flash chromatography at BÃœCHI dates back to the 1980s. Since then, the company has continuously developed this technology, making laboratory work easier and faster for scientists around the world.
The newest Pure Excellence model has been designed from the ground up to meet current technological requirements and the evolving expectations of our customers.
Key features of the modern BÃœCHI Pure Excellence flash/prep system:
• Triple-piston HPLC pump eliminating pressure and flow pulsations
• Four-solvent gradient for demanding separations
• Pressure up to 50 bar (flash) and 400 bar (prep) enabling the use of smaller, more efficient sorbents, saving time and solvents
• UV-VIS DAD detection with real-time 3D spectral display
• Patented ELSD detector with nano-pulse technology, without sample heating, minimal sample loss, and easy nozzle access for cleaning
• Innovative cartridge holder with automatic locking and release
• Injection valve with sample loop for both flash and preparative modes
• Modern, intuitive software
• Wide range of accessories supporting everyday laboratory work
The Pure Excellence systems (models C-905, C-910, C-915, C-950) are the ideal solution for laboratories involved in synthesis, compound purification in pharmaceutical research, specialty chemistry, and natural product isolation.
