Product FAQs

The expiry date of the Biocide Rapide Test will be printed on the exterior of the packaging.  It is manufactured with 1 year shelf life and we try to supply product with a minimum of 6 months remaining.  If you require a longer shelf life than this then please request this at time of order and we endeavour to accommodate your request.

Biocide Rapide Tests should be stored refrigerated between 2-8°C.

The Minimum Inhibitory Concentration (MIC) of the antimicrobial in use might be affected either in a synergistic fashion or antagonistic manner by other chemicals in the liquid being tested.  Therefore it is always recommended to conduct a calibration for the antimicrobial being used in a sample of the liquid.

Standardise your test protocol as much as possible:

• Standardise the time of removal from refrigerated storage before use.  Ensure adequate time is allowed for ampules to reach ambient temperature.
• Standardise the incubation period for each ampule  at 3 hours and 15 minutes (or a time you have decided on for your testing).
• Ensure each operator understands what is a positive and negative result and thus avoid subjective operator errors.
