General description

The DURAN double walled, wide mouth bottles GLS 80 incorporate an integral jacket that isolates the contents from the external environment. Heated or cooled liquids can be circulated through the jacket to control the temperature within the screw topped DURAN bottle. The DURAN double walled bottles offer a sealable and more flexible alternative to open topped jacketed beakers.


  • Simple, low cost, jacketed chemostat or bioreactor for cell culture.
  • Vessel for temperature-controlled reactions such as enzyme digestions.
  • Simple continuous flow stirred reactor system with the optional GLS 80 cap components.
  • Thermostatic vessel to maintain fluids, or high viscosity liquids at a constant temperature, useful when working with endo- or exothermic reagents.
  • Large cold trap or condenser when used with dry ice in the inner container.

Features and Benefits

  • All components are fully autoclavable
  • The wide 65 mm inner diameter of the GLS 80 wide mouth provides easy access to the contents, or for cleaning.
  • The flat inner base is compatible with magnetic stir bars, or the DURAN GLS 80 magnetic stirrer cap system.
  • Compatible with full range of wide mouth GLS 80 connection cap systems for liquid addition or removal during processing.
  • The inner vessel features an easy-to-read graduated volume scale.
  • The GL 18 outlet hose connectors are removable for increased safety
  • The positions of the 10 mm PTFE inlet/outlet hose connectors are optimized for a uniform flow around the jacket to ensure consistent heating or cooling.

Other Notes

The maximum pressure in the double walled glass jacket must not exceed +50 kPa gauge. These products must not be used under vacuum.
