Oxi Control E6 PLX Geobacillus stearothermophilus ATCC® 7953 spores inoculated on poliflex coupons for vaporized hydrogen peroxide sterilization control

USP (United States Pharmacopoeia), EP (European Pharmacopoeia) and DAB (Deutsches Arzneibuch) standards recommend to use bioindicators during sterilization processes. Biological indicators Oxi Control GST E6/E5/E4/E3 PLX are used for regular control of vaporized hydrogen peroxide surface sterilization cycles and validation of sterilizers. These biological indicators use a poliflex support (coupon), that is not permeable to hydrogen peroxide. Poliflex coupon is inoculated with Geobacillus stearothermophilus ATCC® 7953 spores and is inserted into a Tyvek®/Polytene envelope. Tyvek® side of the envelope is permeable to vaporized hydrogen peroxide, while the Polytene side of the envelope is not permeable to vapors. A small circle on the coupon visibly ensures that it is inoculated and correctly oriented in the envelope. Biological indicators Oxi Control GST E6/E5/E4/E3 PLX are produced under strictly controlled conditions in order to satisfy the requirements indicated in the current USP and EP editions and in accordance with ISO 11138 and EN 866 standards.
