RIDA®COUNT - the test sheet that counts for you

Our patented solution for hygiene monitoring and food control.
To meet the increasing demands in routine microbiological analysis,R-Biopharm offers an interesting answer – the RIDA®COUNT test sheets. These sheets have the following benefi ts: easy handling, long shelf life, and minimum space requirement for storage and incubation.

A unique patented fi bre layer provides for all types of applications in food

Fast and safe contact tests / swab tests for checking surfaces, automated air samples and the direct incubation of membrane fi lters, facilitate routine analysis. RIDA®COUNT absorbs liquids applied such as water and beverages
as well as all common diluting media for food samples. A covering fi lm prevents any leakage of sample solution.

RIDA®COUNT provides a combination of hygiene monitoring and microbiological product checks in a simple, safe and economic way.

IDEXX Colilert

USEPA approved method for detecting bacteria in water

An Easy 24 hour test for coliform and E.coli
Colilert has become the number one method in countries around the world because:

  • Colilert takes less than one minute hands-on time per sample
  • Colilert is approved internationally for compliance testing
  • Colilert has been shown to be 20-50% less expensive than traditional methods.
