Funnels

Photo of Drum and Carboy Funnels
Large funnels with handles are ideal for filling drums, barrels, tanks and carboys providing ample volume and fast flow. The two smaller sizes have a handle at the rim. Molded natural polypropylene funnels are autoclavable at 121° C (250° F).

VentSep, a special 1-liter or 2-liter separatory funnel with a built-in relief valve, can be used on Glas-Col's Bench-top Shaker or either of the Glas-Col 3D shakers. That means you can shake up to eight 2-liter funnels or ten 1-liter funnels at once without worrying about pressure buildup. What's more, VentSep features a screw cap instead of a penny-head stopper. As a result, VentSep is safer to use in the laboratory because the screw cap doesn't need restraining and won't come off at inappropriate times, though it will come off easily when you want it to.

Glas-Col's new separatory funnel is designed to offer a new level of convenience and safety when used with Glas-Col shakers. This funnel has a screw cap with a PTFE resin lining to reduce the possibility of contamination. The drain spout is a screw-on PTFE resin design which reduces the chance of breakage and allows for easier cleaning. When used with Glas-Col's new pressure relief valve (S2214F-7, -8), it offers the convenience of self-venting for applications where pressure build-up is a concern.
