The Importance of Steam Quality Tests (SQT)
\n<\/strong>Steam Quality Tests (SQT) are crucial for ensuring the effectiveness of saturated steam sterilization processes. The quality of the steam used directly impacts the safety and efficacy of sterilization.<\/p>\n<\/div>\n

Key Steam Quality Parameters<\/strong><\/div>\n
The main parameters evaluated in steam quality tests are:<\/div>\n
    \n
  • Non-condensable Gases:<\/strong> The volume of non-condensable gases in the steam should not exceed 3.5%. These gases (such as oxygen, nitrogen, CO2, etc.) can reduce sterilization effectiveness by preventing steam from reaching all surfaces of the load. Contrary to common belief, non-condensable gases tend to accumulate at the bottom of the autoclave chamber because they are heavier than water vapor.<\/li>\n
  • Superheat:<\/strong> Steam should not be superheated by more than 25\u00b0C above the saturation temperature. Superheated steam decreases sterilization effectiveness.<\/li>\n
  • Dryness:<\/strong> The dryness value of the steam should be at least 0.9 (90%) for metal loads and at least 0.95 (95%) for porous loads. Excessively wet steam can cause condensation on the load, reducing sterilization effectiveness.<\/li>\n<\/ul>\n
    The EN 285<\/strong> standard sets the requirements for verifying these parameters, ensuring that every sterilization process meets high standards.<\/div>\n
    \n

    Our Approach
    \n<\/strong>Our dedicated qualification team regularly performs these tests, ensuring continuous monitoring and maintaining the highest levels of safety and compliance.<\/p>\n

    Conclusion
    \n<\/strong>Regularly conducting SQT is essential to maintain sterilization effectiveness and protect patients.<\/p>\n<\/div>\n
