Glas-Col offers several sizes of Pestles & Tubes to homogenize plant tissue, food, biological samples and other substances.  The Pestle forces the disruption of the physical material for further analysis.

Separatory funnels are used to separate immiscible liquids from their solutes. Glas-Col separatory funnels are designed with PTFE resin lined screw caps to reduce the possibility of contamination. The drain spout is also a screw on PTFE design that reduces the chance of breakage and allows easier cleaning.  Automatic venting is available on some models.
