Description

Utilize these chemically inert, translucent and autoclavable funnels which feature a TFE stopcock assembly. Chemical-resistant, leakproof and requires no lubrication.

Perform your liquid-liquid extractions with these chemically inert, translucent and autoclavable Thermo Scientific™ Nalgene™ Separatory Funnels made with Teflon™ fluoropolymer and Closure made with Tefzel™ which feature a TFE stopcock assembly. TFE stopcock assembly has excellent chemical resistance, is leakproof† when used with provided Nalgene closure and does not require lubrication — can be chemically disinfected. More transparent than our polypropylene separatory funnels. Compatible with all common lab reagents and solvents. Won't chip, crack or shatter like glass separatory funnels.

Features:
  • Break-resistant and impervious to any chemical used in a separatory funnel
  • No phthalates to contaminate analyses
  • Useful in radiological and hazardous separations
  • Autoclavable/Leakproof
  • Stem length: 65mm

Teflon™ FEP funnel, TFE stopcock and Tefzel™ ETFE screw closure

† The term leakproof applies to Thermo Scientific Nalgene products that meet the following criteria: a) Bottle/flask/funnel closure systems with closures smaller than 100mm, after they are filled with water, inverted, withstand air pressure of 2 psig for 2 minutes, and no water escapes. b) Bottle/funnel/flask closure systems of larger than 100mm after they are filled with water, inverted for 15 minutes, and no water escapes.

Note: these tests, using other liquids, may not yield the same results. To ensure safe usage, customers are advised to test Thermo Scientific Nalgene bottles and closures under conditions of their planned applications. Thermo Scientific Nalgene products are leakproof at ambient temperature and pressure when used with their Nalgene closures.
