Nalgene® Separatory Funnels

Nalgene® Separatory Funnels Close

Choose Teflon® FEP Resin or Polypropylene

Autoclavable, except for stopcock assemblies which remove easily for chemical disinfecting. Stem length below stopcock is 65mm on all funnels. Safe to use with a mechanical shaker—just attach hose clamp over the stopcock insertion area. Teflon® FEP Resin Funnels are completely impervious to any chemical used in a separatory funnel—ideal for use in radiological and hazardous separations. Economical Polypropylene Funnels stand up to many chemicals, including hydrofluoric acid, but do not have the chemical resistance of Teflon.
