PURE SOLUTIONS: The filtering lab flask can be used to separate components or impurities in your mixtures or solutions. The filtration apparatus is built to last with tough, heat resistant borosilicate glass designed to handle boiling liquids and strong vacuums.

FAST FILTERING ACTION: The filtering and distillation kit can be used with or without a vacuum. For faster, higher volume jobs, just hook up a vacuum hose to the filtering flask and quickly pull your solution through the funnel. A lab vacuum filtration apparatus allows you to filter oil and water soluble solutions without damaging or losing heat-sensitive compounds in a distillation. This filtering flask comes with a high quality rubber stopper and aluminum clamp that allow for strong vacuums.
