DURAN double-walled, wide-mouth GLS 80 bottles

Monday, 30 March, 2015 | Supplied by: LabFriend

The DURAN double-walled, wide-mouth GLS 80 bottles 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 bottle. The double-walled bottles offer a sealable and flexible alternative to open-topped, jacketed beakers.

The bottle is a simple, jacketed chemostat or bioreactor for cell culture, which is also used as a vessel for temperature-controlled reactions such as enzyme digestions. The design allows for a simple, continuous, flow-stirred reactor system that can be customised with the optional GLS 80 cap components.

The bottle is a suitable thermostatic vessel to maintain fluids or high-viscosity liquids at a constant temperature, which is useful when working with endothermic or exothermic reagents. Dry ice in the inner container can be used as a large cold trap or condenser. The versatile bottle is manufactured from DURAN borosilicate 3.3 glass, featuring good thermal performance and high resistance to chemical attack.

The bottles have a wide usable temperature range of -40 to +120°C, which can be extended from -45 to +180°C with the optional white GLS 80 polyethersulfone cap. DURAN glass components are usable from -196 to +300°C, with care taken to limit the rates of heating or cooling. All components are fully autoclavable.

The product is available in two sizes: 500 and 1000 mL. The 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. The product is also compatible with 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 and the GL 18 outlet hose connectors are removable for increased safety. The positions of the 10 mm PTFE inlet/outlet hose connectors are optimised for a uniform flow around the jacket to ensure consistent heating or cooling.
