The Benchmark Scientific B3000-2000-G Hybex Reusable Media Bottles are manufactured from high quality, borosilicate 3.3 glass. With their superior chemical resistance, the Benchmark Scientific B3000-2000-G bottles are ideal for storage of reagents, culture media, biological fluids and a variety of other aqueous and non-aqueous solutions.

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 can withstand temperatures from -70 to 500°C, permitting repeated use in freezers, microwaves, autoclaves and dry heat sterilization chambers.

The Benchmark Scientific B3000-2000-G Hybex Media Bottles include a drip-free sealing ring as well as a standard blue polypropylene (GL45) sealing cap. The bottles come with green colored caps.
