SolVac® Filter Holder cat. no 4020

Simplifies Clean-Up and Degassing of Mobile Phase Solvents and Other Solutions Versatile design fits most HPLC bottles, flasks, and containers, and eliminates the added steps of washing flasks and transferring mobile phase solvent from flask to reservoir. Draws directly from HPLC solvent bottle. Less likely to spill aggressive solvents than glass funnels or disposable cups. Durable plastic construction is less likely to break than glass funnels, assemblies, or adapters. Patented magnetic seal is reliable and leak proof. Eliminates the possibility of membrane shifting or tearing which can occur with aluminum clamps or threaded holders. Reusable, chemically resistant polypropylene construction is resistant to common HPLC mobile phase solvents such as methanol, acetonitrile, and tetrahydrofuran.
