Biological Indicators

For validation and routine monitoring of sterilization processes biological indicators are still considered as a golden standard because they offer a direct proof of microbial inactivation. However, a great variation in the resistance characteristics of biological indicators demands a meticulous analysis of each production batch.

Therefore, it is worth to verify resistance and population of biological indicators before using them.

Vitality

Testing of spore strips, ampoules and SCBIs as well as other biological indicators for viable spores.

Population

Determination of the population of biological indicators according to ISO 11138-1 and USP.

Purity and Identity

Testing of biological indicators for contamination with other microorganisms and verification of the identity of the test organism.

Analysis of the resistance characteristics

Under sterilization conditions in stream, dry heat, EO, LTSF, H2O2.

Our test laboratory is accredited by DAkkS according to EN ISO/IEC 17025.
