Vacuum Manifold
Solid and stable on the benchtop. 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 stopcock on each valve shuts off flow when fewer than three outlets are used. Barbed fitting accepts 3/8-in (9.5-mm) I.D tubing. For simultaneous filtrations with increased filtrate volume in particulate and microbial analysis, use with Nalgene filter funnel with clamp (Cat No.DS0315-0047), a complete filtration system. May also be used with Nalgene analytical filter funnel (Cat No's 140, 145 and 147) and filter holder with funnel (Cat No's DS0310-4000 & DS0310-4050).
