Large-Capacity Vacuum Filtration System

The HNZXIB ZF-50L provides a 50L receiving flask for laboratories that process high volumes of liquid. It is built for university research, biopharmaceutical production and environmental monitoring facilities. The GG17 high borosilicate glass flask offers high transparency and durability. A bottom outlet valve allows convenient drainage without moving the heavy vessel.

Upgrade from Smaller Batch Filtration

This unit replaces multiple smaller filter assemblies when throughput demands exceed their practical limit. The jump is worth it when a single 50L batch reduces handling steps and contamination risk compared to repeated runs. The 304 stainless steel Buchner funnel resists corrosion and simplifies cleaning between batches. Lockable casters on the support frame let operators position the rig safely before locking it in place.

Sustained Operation Under Vacuum

The oil-free vacuum pump maintains a continuous negative pressure differential across the membrane during long filtration cycles. The professional vacuum hose and wooden case packaging protect the glass and frame during transport and setup. Stainless steel construction on the funnel and frame withstands repeated thermal and chemical exposure. The system is designed for uninterrupted runs rather than short intermittent use.

Questions about this item

What size flask opening does the 50L GG17 borosilicate receiving flask use for the stainless steel Buchner funnel?

The 50L GG17 high borosilicate glass receiving flask accepts the stainless steel Buchner funnel at its standard ground-glass joint; the funnel seats directly on the flask neck without extra adapters.

How is the 304 stainless steel support frame with lockable casters assembled, and what step is often missed?

Bolt the frame sections together, mount the four lockable casters, then level the frame before placing the 50L flask — skipping the leveling step makes the bottom outlet valve hard to operate.

Which parts of the ZF-50L filtration unit need periodic replacement during routine laboratory use?

The microporous membrane, filter paper or filter cloth fitted in the Buchner funnel are consumables; replace them when flow rate drops or after each filtration batch.
