50L vacuum filtration system

The HNZXIB GZF-50L is a 50-litre vacuum suction filtration unit built for university labs, research institutes, biopharmaceutical facilities and environmental monitoring stations. It uses a GG17 high borosilicate glass funnel with a PTFE orifice plate to create a Buchner funnel effect for visible solids and particle removal.

GG17 glass and PTFE orifice plate

The funnel material provides high transparency and chemical resistance so operators can watch the filtration process in real time. The PTFE sealing surface ensures broad solvent compatibility while the 304 stainless-steel frame with lockable casters adds mobility and stability during use.

Bottom outlet valve and pump requirement

A discharge valve at the base of the receiving flask allows liquid removal without disassembly. The system needs a separate vacuum pump to generate negative pressure at the filter bottle base; buyers must confirm pump compatibility and verify that the 80 mm sealing interface matches their existing hardware.

Questions about this item

How often should the PTFE orifice plate on the 80 mm seal be replaced?

The PTFE orifice plate resists most laboratory chemicals, so replacement is only needed if it becomes scratched, cracked or chemically attacked during filtration.

What limits continuous operation of the 50 L GG17 borosilicate funnel?

The 290 mm diameter by 350 mm high glass funnel and the 50 L receiving flask define the maximum batch volume per run.

How much noise and heat does the 304 stainless frame with lockable casters add during all-day use?

The frame and casters are passive components; they generate no noise or heat themselves.
