  • FEP provides excellent chemical resistance
  • Use in temperatures from -100° to +150°C
  • For proper performance, must be filled to 100% of total capacity
  • For added leakproof† asssurance at maximum speeds or when spinning hazardous materials use with PP sealing caps assemblies (DS3131-0038)


When spinning 250mL bottle in a Sorvall GSA rotor, use of the Nalgene centrifuge bottle adaptor (DS3125-0250) is required.


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.
