Stirred nutsche filters by Büchi are used for filtration as well as for solid phase peptide synthesis (SPPS). They can easily be combined with Büchi 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 (büchiflex) glass system under full vacuum.

As solid phase reactors, they can be equipped for fully automated processes. Stirrers are provided in glass lined steel, Hastelloy or stainless steel. The stirrer height can be adjusted pneumatically under full vacuum operation condition, which enables the squeezing of the slurry.
