Glass vessel: 30 liter Pressure: -1.0 (FV) to +0.5 bar Temperature: -60 °C to +200 °C Material: Glove made of EPDM For other materials and characteristics, see nutsche filters Buchi high containment nutsche filters allow for controlled filtration with a contained discharge by wiping out with a contained discharge by wiping out with the fixed glove (made of EPDM) into a bag system. The purpose of this filter is controlled filtration with a contained discharge by wiping out with the fixed glove into a bag system. The filter vessel can easily be lifted, lowered and tilted due to its versatile and solid stand. Glass vessel::30 liter Pressure:-1.0 (FV) to +0.5 bar Temperature:-60 °C to +200 °C

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

Metal vessel: 5, 10, 20 liter Pressure: -1.0 (FV) to +6.0 bar Temperature: -10 °C to +200 °C Filter: sintered 8 to 115 micron Material: stainless steel, Hastelloy® C22 These robust and compact pressure filters are designed for filtration, pressurizing the vessel with up to 6 bar pressure. They offer a removable filter basket, a quick opening / closing system and a perfect fit to Buchi pressure reactors, allowing for an easy operation. The filter vessel is jacketed and can be temperature controlled by a circulator. Process connections are standard Tri-Clamp configuration. Pressure vessel:5 to 20 liter Pressure:-1 (FV) to 60 bar Temperature:-10 °C to +200 °C

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. 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
