The Benchmark Scientific B3220-2000 2000ml hybex Erlenmeyer Flask with GL45 Cap is manufactured from high quality, borosilicate 3.3 glass. A low coefficient of thermal expansion (3.3), provides temperature resistance that is far superior to that of standard lab glass (or soda lime glass). Hybex glass is designed to withstand high temperatures, making them ideal for shaking applications, media preparation and long-term storage.
The Erlenmeyer flask has permanent, white enamel graduations for volume measurement and a white identification box for marking or coding.
For storage of media and cultures, the capped flask includes an autoclavable polypropylene cap and drip-ring. Optional cap colors are available separately, as well as PBT material caps for temperature applications up to 180°C. Threads are standard GL-45 for compatibility with a wide range of cap types from various manufacturers, including phenoic caps, vented caps, etc.
