The Microbiological Challenge Testing : in-line microbiological qualification

How to make sure your Claranor device is really performing and truly delivers the required level of decontamination in-line?

Not only do we regularly collaborate with independent laboratories such as Fraunhofer, INRA or CNRS to validate our technology on a scientific basis, but we perform in-line testings in your premise to assure your operational efficiency. 

To ensure this a Claranor microbiologist can perform a complete set of testings during operation, theto “the customer's site to carry out the tests during operationMicrobiological Challenge Testing”. 


Objective of the Microbiological Challenge Testing (MCT) :

Demonstrate the efficiency of the Pulsed ligth system unit installed on the filling line.

  • Perform the MCT in industrial conditions :
    • proper running configuration
    • right nominal speed of the line
  • meet the customer requirement in terms fo log-reduction of test micro-organism.

Principle of the MCT : 

  • Samples of packaging inoculated beforehand with the reference microorganism
  • This packaging is placed on the line, under operating conditions, and treated by the Claranor Pulsed light equipment
  • It is then removed from the line and analyzed, searching for residual microorganisms, in order to determine the log reduction obtained

Impartiality of the MCT :

The tests are carried out :

  • with the assistance of an external laboratory for the inoculation of the packaging, and carrying out the analyses.
  • aligned with the VDMA (German Engineering Federation) recommandations.
  • The tests must demonstrate the consistency of the results under operating conditions with those obtained under static conditions in the context of pre-sales tests.
