Nutsch filters

Reactor Systems

BÜCHI nutsch filters can easily be combined with reactors for solid / liquid separation after the synthesis. The inert materials allow safe processing in an inert atmosphere of a wide range of solvents and acids in a completely sealed (buchiflex) glass system under full vacuum. The stirred nutsch filters are available for filtration and for solid phase peptide synthesis (SPPS). As solid phase reactors, they can be equipped for fully automated processes.
Mobile nutsch filters for safely separating solids and (inert) liquids after synthesis. Also SPPS. Including lift.

The use of glass nutsch filters

BÜCHI filters are used for safely separating solids and (inert) liquids after synthesis. After synthesis, the slurry is transferred into the filter. The solid content in the slurry is held back by the filter cloth forming a filter cake, while the filtrate runs away to the outlet valve in the bottom plate.

The cake is removed easily from the top by opening the cover and lowering the glass filter vessel, which is fixed to the lifting device. The same lifting device is used to lower the bottom for accessing the filter cloth for easy cleaning or exchange.
