Biological indicators OXI CONTROL GST E6/E5/E4/E3/E2 SS are used for regular control of H2O2 vapour superficial decontamination cycles and validation of sterilizers. These biological indicators use a stainless-steel support (coupon), that is not permeable to hydrogen peroxide. Stainless-steel coupon has been inoculated with Geobacillus stearothermophilus ATCC® 7953 spores and has been introduced into a Tyvek®/Polytene envelope. Tyvek® side of the envelope is permeable to hydrogen peroxide vapor, while the Polytene side of the envelope is not permeable to these vapors. Biological indicators OXI CONTROL GST E6/E5/E4/E3/E2 are produced under strictly controlled conditions in order to satisfy the requirements indicated in the USP and EP current editions and in accordance with ISO 11138 and EN 866 standards.
