"Biohazard Bags 25"" x 35"", Orange Autoclavable. Bio-Check biohazard bags are constructed of high-integrity polypropylene and are designed to withstand the maximum autoclave temperature of 270F (132C), so you can use faster sterilization processes. The elastomer closure allows the bag to expand and vent steam during cooling. All bags resist punctures, tears and leaks and meet the 165g dart drop test as required by ASTM D1709-98. Choose from orange, clear or red plastic, each imprinted with the universal biohazard symbol."
