Mesh filters - Import export

Glass vessel: 10 - 300 liter Stirred nutsche filters are used for filtration as well as for solid phase peptide synthesis (SPPS). Solid phase reactors 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, enabling squeezing of the slurry. Pressure: -1.0 (FV) to +1.0 bar Temperature: -60 °C to +200 °C Filter cloth: Mesh size 8 to 115 micron Material: Borosilicate glass 3.3, PTFE, PFA, ETFE, glass-lined steel

Nutsche filters for reactors and pilot plants Glass vessel: 10, 30, 50, 100, 140, 300 liter Pressure: -1.0 (FV) to +0.5/ 1.0 bar Temperature: -60 °C to +200 °C Filter cloth: Mesh size 8 to 115 micron Material: Borosilicate glass 3.3, PTFE, PFA, ETFE A clean-room setup and other materials are available to meet your specific process requirements. Buchi nutsche filters can easily be combined with our 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 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 filtering stage ends when the filtrate is of small quantity, which can be shortened by squeezing the filter cake by turning the height adjustable stirrer.
