Designed with three vacuum outlets, each with leakproof, two-way valve and vent port. Each outlet securely holds a No. 8 stopper and the stem of a filter funnel without interference. Outlets are spaced for easy manipulation of individual funnels. Teflon® resin stopcock on each valve shuts off flow when fewer than three outlets are used.

For simultaneous filtrations with increased filtrate volume in particulate and microbial analysis, use filter funnel with clamp. May also be used with Nalgene® analytical filter funnels or filter holders with funnel.
