Challenge test automation

Challenge Tests automation with TEMPO® increases throughput and delivers results faster, which increases flexibility and shortens the product development cycle.

Tempo is an automated system for microorganisms enumeration. It is miniaturized and an optimized MPN method (16 tube repetition) that allows quantification compliant with USP <1223> and ISO 11930.


It requires 2 ergonomic stations to perform the enumeration:

-          TEMPO® filling station to fill TEMPO® cards with your inoculated cosmetic samples
and Tempo culture media containing a fluorescent indicator

-          TEMPO® Reader instrument for an automated enumeration in CFU/g or ml
