Maintenance-free chromatography system

Robust and maintenance-free hardware is the main requirement for a strong and reliable chromatography system. Büchi has recently developed a new modular Flash chromatography system which is based on medium pressure chromatography technology.

In other words all the components of the instrument like sealing disks, pump piston etc. are originally designed for the medium pressure application. This guarantees a long lifetime of the instrument and its components.

The Büchi Sepacore system shows also a very constant solvent flow because of its three piston pump. This is on the one hand improving the separation quality by working at a pressure range of 0­10bar (0­145psi).

On the other hand, a constant solvent flow is one of the most important factors responsible for a long lifetime of the instrument as well as the sealing. Even the strongest sealing disk or other components of an instrument will burst if they are hit all the time as happens with a pulsing volume flow.
