The Benchmark Scientific B3000-SP-AS Hybex reusable media bottles are manufactured from high quality, borosilicate 3.3 glass. With their superior chemical resistance, these 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. All hybex media bottles from the B3000SPAS include a drip-free sealing ring as well as a standard blue polypropylene (GL45) sealing cap. Bottles are also available with green, purple, white and yellow caps, or in an assortment pack containing two of each color. The Starter pack includes 10 bottles that consist of 2 100ml, 3 250ml, 3 500ml, and 2 1000ml bottles with sealing rings and caps, two of each color: blue, green, purple, white, and yellow.
