Filter Flasks Filter Flasks are thick-walled Pyrex® glass and have side tubulation for .375in (9.5mm) I.D. vacuum tubing. When used in conjunction with Indicating Drierite Granules filter flasks can be used as a moisture trap for vacuum pump protection. Neoprene Stoppers and Neoprene Stoppers w/ Glass Tube are available to fit each size of filter flask.
