Effectively perform organic solvent and concentrated oxidising agent work with Thermo Scientific™ Nalgene™ erlenmeyer flasks made with Teflon™ fluoropolymer and closure made with Tefzel™, which are unbreakable, autoclavable, nearly transparent and resist virtually all chemicals. Combine the excellent chemical resistance of FEP with the convenience of a screw closure. These flasks can be a valuble element of lab safety programs.

• For trace metal work, chemically sterilize or boil in concentrated nitric acid
• Withstand temperatures from -270 to +205°C (-454 to +401°F); closure, from -100 to +150°C (-148 to +302°F) for a wide range of demanding applications
• Screw closure prevents spills and contamination
• Autoclavable
