Electron Microscopy Sciences hybex™ Media Storage Replacement Cap Standard, GL45 Cap, Assorted
Reusable media bottles manufactured from high quality, borosilicate 3.3 glass. They feature superior chemical resistance and are ideal for the storage of reagents, culture media, biological fluids and many other aqueous and nonaqueous solutions.
All hybex bottles have permanent white enamel graduations for volume measurment, along with a white identification box for coding or marking.
With a low coefficient of thermal expansion (3.3), these bottles can withstand temperatures from -70 to 500 deg C. This allows for repeated use in freezers, microwaves, autoclaves and dry heat sterilization chambers.
