Filtration and separation equipment
Vacuum filtration apparatus, Buchner funnels, fritted glass, filtration flasks, chromatography columns and TLC accessories.
Overview
Filtration setups are chosen by the solid–liquid ratio, the particle size and whether the filtrate or the solid is the product. A Buchner funnel and filtration flask suit fast vacuum filtration; a fritted glass funnel is better for fine precipitates and solvent compatibility; chromatography columns and TLC accessories cover separation beyond simple filtration.
We supply filtration apparatus, Buchner funnels, fritted funnels, filtration flasks, adapters, chromatography columns and TLC accessories. Replacement parts are available for common setups; see filtration accessories or contact us.

How to choose
Funnel type
Buchner funnels are fast and suit medium to large crystals. Fritted glass funnels handle fine precipitates and aggressive solvents better.
Frit porosity
Porosity controls retention and flow rate. Match it to the particle size and whether the solid or the filtrate is the product.
Flask and vacuum
Use a thick-walled filtration flask rated for the vacuum source, with a trap between the flask and the pump.
Frequently asked questions
Which setup should I use for vacuum filtration?
A Buchner or fritted funnel, a thick-walled filtration flask and a vacuum trap. The funnel diameter should match the volume you are filtering.
How do I choose frit porosity?
Match porosity to the particle size and flow requirement. Coarser frits flow faster; finer frits retain smaller particles.
Buchner or fritted glass?
Buchner is faster for medium and large crystals. Fritted glass is better for fine precipitates and solvents that attack paper.
Can I order replacement frits and seals?
Replacement parts are available for common setups; check the filtration accessories category or contact us.
Do you offer custom frit sizes?
Send the diameter, porosity and intended use; we will confirm whether we can quote it.
Need a custom size or a complete setup?
Send a drawing, parts list or the conditions you are working with. We will confirm compatibility and quote.
