Steam sterilization biological indicator 83161

temperature

Steam sterilisation (or autoclaving) is carried out by introducing saturated water vapour under pressure. In addition to the temperature effect itself, the presence of saturated water vapour is essential for killing microorganisms, their destruction being due to irreversible denaturation of cell components. Chemical indicators for autoclaves (steam) Product description Chemical indicators (CI) register as many relevant sterilisation parameters as possible, such as, for example, air expulsion and steam penetration ability, temperature, pressure and time. Chemical indicators consist of a coloured chemical compound deposited as dots on a paper strip. This chemical compound has the property that it changes colour from light blue to black when the value of the critical physical parameters for sterilisation has been attained. Chemical indicators are a good supplement to biological indicators and must be used daily to provide rapid indication of whether the critical parameters were correct during sterilisation. However, they are no substitute for biological indicators. Only the biological indicators can be used for measuring the efficacy of the sterilisation process. Chemical indicators are class 5 indicators, which are produced in accordance with the requirements of the ISO 11140-1 standard. By using chemical indicators you protect your staff and patients from bacterial infections transferred from non-sterilised utensils Our indicators are of high quality. We are following the guidelines from NIR to secure the highest standard of your sterilisation process. Chemical Indicators are your daily quality check of your autoclave
