CP Lab Safety's plastic Chromatography Funnels are virtually unbreakable and made of chemically resistant high density polyethylene (HDPE). They are spark proof, rust proof, dent proof and boil proof.

These uniquely designed funnels have perforated sides and a closed stem, which facilitates the gentle addition of solvent without disturbing the silica gel by allowing solvent to flow down the column wall, making these superior to ordinary funnels.
