The double-walled DURAN
® wide neck bottle GLS 80
® is thermally insulated by its integrated glass cladding. To regulate the temperature in this DURAN
® screw cap bottle, hot or cold liquids can be circulated through the cladding. The double-walled DURAN
® bottles are a lockable, flexible alternative to cap-less beakers with cladding.
Applications:
- Suitable for use as simple, low-cost chemostat or bioreactor with double cladding for cell cultures;
- Reaction vessel for temperature-controlled reactions such as enzyme digestion;
- Simple stirring reactor system with continuous flow and optional GLS 80® cap component;
- Thermostatic vessel for storing liquids, or highly viscous liquids at a constant temperature – practical for working with endo- or exothermal reagents;
- Can be used as large cold trap or cooler with dry ice in the interior container.
Features:
- Fit for use in a wide temperature range of -40 to +120°C. By means of the white GLS 80® polyethersulfone screw cap (order separately), the application range can be extended to -45 to +180 °C. Laboratory glasses made of DURAN® glass can be used in a temperature range of -196 to +300°C; however, the limit values for heating or cooling must be observed.
- Made of DURAN® borosilicate glass 3.3, a material with proven excellent thermal properties and a high resistance to chemical loads.
- All components are fully autoclavable.
- Available in two practical sizes: 500 and 1000 ml.
- The inner diameter of 65 mm of the thread of the GLS 80® wide neck bottle allows for simple and convenient filling and emptying as well as cleaning.
- Thanks to its flat bottom, the bottle is suitable for use with magnetic stir bar or the DURAN® GLS 80® magnet-stirring cap system.
- Compatible with all GLS 80® wide neck connection systems for adding or removing of liquids during processing.
- Easy-to-read scale on the interior vessel
- For greater safety, the GL 18 outlet hose connections can be removed.
- To ensure even heating or cooling, the position of the 10 mm PTFE inlet / outlet hose connections was optimised for constant flow around the cladding.
