Biological indicators are the ideal process indicators that directly monitor the lethality of a given sterilization process. Tailin’s biological
indicators meet the requirements of ISO 11138, GB18281, GMP, PDA TR51, FDA 510k and Pharmacopoeia (USP, EP, ChP). The spores
used are traceable and the test report includes spore concentration, D-value, and other relevant data.
Rapid and ultra-rapid self-contained BIs are designed for fast monitoring of steam sterilization effectiveness. After sterilization, the indicators are incubated in the HTY-RBIR100 Rapid BI Reader, which determines the result based on fluorescence signal changes. Ideal for hospital operating rooms, CSSDs, and other healthcare facilitie.
No. According to ISO 11138, BIs are defined as the only means to provide direct evidence of microbial kill. USP <1229> further clarifies that while physical and chemical monitoring provide real-time data, they are “indirect” measures.
The color change of a CI only proves that the sterilant has “reached” the area; it does not represent that microorganisms have been completely eradicated. In annual re-validations and routine batch releases, a negative BI result is an indispensable legal basis.
Yes. Tailin states that its Biological Indicators comply with multiple international standards and guidelines, including ISO 11138, USP, EP, GMP, PDA TR51, FDA 510(k), and GB18281 requirements. In addition, the spores are traceable and test reports include important validation data such as spore concentration and D-values.
The self-contained design helps reduce operator handling steps and lowers contamination risk. Tailin also uses medical-grade dialysis paper packaging that both prevents external contamination and ensures adequate steam penetration during sterilization cycles.
