Buchiglas – Nutsche filters 10 – 300 liter
Solid-liquid separation for kilo labs, pilot plants / scale-up and small-scale production. Effortless operation and cake removal thanks to lifting devices, tilting mechanism and removable filter cloths. Glass nutsche filters operate from full vacuum up to +0.5 bar, pressure nutsche filters in stainless steel or Hastelloy® handle demanding applications up to 6 bar. Full compliance with cGMP requirements and regulations such as ATEX and PED.

Nutsche filters 10 – 300 liter
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.
Specifications:
- Filtration vessel:10, 30, 50, 100, 140, 300 liter
- Pressure:-1.0 (FV) to +0.5 bar
- Temperature:-60 °C to +150 °C (200 °C)
- Filter cloth:Mesh size 8 to 115 micron
- Material:Borosilicate glass 3.3, PTFE, PFA, ETF
Applications
- Filtration / Separation
- Solid phase peptide synthesis (SPPS)
- Drying
- Chromatography
- Purification
- Cannabis extraction (solvent extraction)
- Crystallization
- Cannabinoid extraction
- Ion exchange
- Cannabis extract purification
- Peptide synthesis
- Cannabis winterization (cannabis extract winterization)
High containment nutsche filter for reactors and pilot plants
Buchi high containment nutsche filters allow for controlled filtration with a contained discharge by wiping out with the fixed glove (made of EPDM) into a bag system. The filter vessel can easily be lifted, lowered and tilted due to its versatile and solid stand.
Specifications:
- Filtration vessel:30 liter
- Pressure:-1.0 (FV) to +0.5 bar
- Temperature:-60 °C to +200 °C
- Material:Glove made of EPDM
Applications
- Filtration / Separation
- Filtration of HPAPIs (highly potent APIs)
- Filtration under protective atmosphere
Stirred nutsche filters for reactors and pilot plants
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 nutsche filters for process filtration
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.
Specifications
- 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
Applications
- Filtration / Separation
- Drying
- Purification
