Thermo Scientific™ Nalgene™ Separatory Funnels

Nalgene separatory funnels are a safer alternative to glass. They won’t break, chip or shatter amid the bustle and bumps of everyday lab work. Enjoy their light weight and ease of handling. Trust Thermo Scientific Nalgene separatory funnels to be made from the highest quality laboratory-grade polypropylene copolymer (PPCO) and fluoropolymer (FEP) materials for dependably low extractables across a wide variety of lab applications.

Choose polypropylene for its low cost and good chemical compatibility with a wide range of lab chemicals. FEP provides the ultimate in chemical resistance and inertness for the most demanding liquid phase separations. Rely on leak-free performance with our Nalgene leakproof* guarantee.

Thermo Scientific™ Nalgene™ Polypropylene Separatory Funnels with Closure

Nalgene™ PPCO Separatory funnel and PP screw closure are chemically resistant, translucent and autoclavable.

Polypropylene copolymer body and Teflon® TFE stopcock assembly has excellent chemical resistance, is leakproof† and does not require lubrication.

details

  • Separation lines between immiscible liquids easily observed
  • Phase interface is observable down to the stopcock
  • TFE stopcocks need no lubrication; saves time and no messy grease
  • Funnel is chemically compatible with a wide range of lab reagents
  • Funnels are susceptible to softening and swelling from extended exposure to aggressive solvents though the effect is reversible
  • Autoclavable/Leakproof†

Ordering Information: Stem lengths, 65 mm.

Notes: Autoclavable except for stopcock assembly, which is easily removed and chemically sterilized.

Thermo Scientific™ Nalgene™ Separatory Funnels made with Teflon™ FEP with Closure

Nalgene™ FEP Separatory funnel and ETFE screw closure are chemically inert, nearly transparent and autoclavable.

More transparent than our polypropylene separatory funnels. This funnel is compatible with all common lab reagents and solvents. Won’t chip, crack or shatter like glass separatory funnels. Teflon® FEP stopcock assembly has excellent chemical resistance, is leakproof† and does not require lubrication – can be chemically disinfected.

details

  • So transparent that phase interface is visible down to the stopcock and nonwetting surface
    – enhances complete drainage
  • Break-resistant and impervious to any chemical used in a separatory funnel
  • No phthalates to contaminate analyses
  • Useful in hazardous separations
  • Autoclavable/Leakproof†

Ordering Information: Stem lengths, 65 mm.

Notes: Autoclavable except stopcock assembly, which is easily removed and chemically sterilized.
