Vacuum filtration and nutsche filter reactors for solid-liquid separation.

Products
Vacuum filtration and nutsche filters separate solids from liquids by pulling or pushing the slurry through a porous medium, leaving a filter cake on top while clarified filtrate passes through. The category spans simple Buchner funnels and sintered-glass filters for bench work up to closed nutsche filter reactors and agitated nutsche filter dryers (ANFD) that combine filtration, cake washing, and vacuum drying in one vessel.
In a cannabis lab these handle the routine solid-liquid steps: removing biomass from ethanol extract, filtering precipitated waxes and fats after winterization, and clearing spent activated carbon after color remediation. Coarse media catch biomass, while fine cloth or sintered discs down to a few microns are used for polishing and carbon removal. Larger crystallization-to-isolate workflows lean on jacketed nutsche units for temperature control.
Choose by batch volume, driving force, and media. Match filtration area and working volume to your slurry size and target cycle time. Decide between vacuum (simple, ~0.8-1 bar differential) and pressure-rated nutsche designs (stronger driving force for viscous or compressible cakes). Specify media micron rating and chemical compatibility, and add a jacket only if you need controlled-temperature washing or drying.
