20L vacuum filtration system

This 20L glass filtration assembly combines a GG17 borosilicate funnel with a PTFE perforated plate to create a Buchner-style filter. A 304 stainless steel frame on lockable casters supports the receiving flask and its bottom discharge valve. The unit arrives in a wooden crate from California.

Suitable for laboratory separations

Designed for universities, research institutes and biopharmaceutical labs that need visible filtration of solids, particles or microorganisms from liquids. Not suited for buyers who require heated or pressurised filtration, automated cleaning cycles or capacities beyond 20L.

20L funnel capacity

The GG17 high borosilicate glass funnel holds 20L and measures 400 mm in diameter by 240 mm in height. It mates with an 80 mm PTFE sealing surface and a 50 mm bottle mouth, defining the maximum batch volume per run.

Questions about this item

Should I pick the 20 L funnel or a different capacity?

The GZF-20L provides a single 20 L funnel capacity; no other sizes are offered in this listing.

What does the 20 L capacity mean when the unit is running?

It indicates the funnel can hold up to 20 L of liquid during vacuum suction filtration before the receiving flask needs emptying.

What interface does the 80 PTFE seal connect to and what does it limit?

The 80 PTFE sealing surface mates with the 80 × 50 filter bottle mouth, limiting the connection to that specific flange size.
