This Hybex reusable media bottle starter pack includes two 100mL, three 250mL, three 500mL, and two 1000mL bottles (total of ten bottles). Manufactured from high quality borosilicate 3.3 glass with its superior chemical resistance, each bottle is 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. Each Hybex bottle has permanent white enamel graduations for volume measurement, and a white identification box for marking or coding. Each includes a drip-free sealing ring as well as a standard blue polypropylene (GL45) sealing cap.
