SolVac® Filter Holder

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.
