WIGGENS new separatory funnel is designed to offer a new level of convenience and safety when used with WIGGENS shakers. This funnel has a screw cap with a Tefon® resin lining to reduce the possibility of contamination. The drain spout is a screw-     on Tefon® resin design which reduces the chance of breakage and allows for easier cleaning. When used with WIGGENS's new pressure release valve (see page 50), it offers the convenience of self-venting for applications where pressure build-up is a concern.

When used with the WIGGESN Pressure Release Valve, this separatory funnel becomes self-venting.
