TransFast® System

Non-alcoholic beverage spoiling microorganisms

Easy-to-use comprehensive solution for the qualitative detection of non-alcoholic beverage spoiling microorganisms results in less than 48 hours.

The TransFast® System is suitable for your qualitative analysis of:

  • ready-to-drink beverages
  • beverage compounds
  • fruit juice concentrates
  • rinsing water samples
  • membrane filtered samples

Product description

The TransFast® system is the reliable and fast cultural method for the qualitative detection of yeasts, moulds, lactic and acetic acid bacteria in beverages with a pH < 4.5 in less than 48 hours.

While in classic detection, the agar has to be liquefied and poured into Petri dishes, the carrier system for TransFast® is a transparent, pourable gel. Usually pre-enriched in TransFast® Broth, the sample is filled into a transparent tube together with the TransFast® Gel and incubated.

Depending on the bacterial contamination, first results can be seen after just 24 hours. This allows a comprehensive detection and provides results in a shorter incubation time.

Another innovation is the TransFast® Incubation Lightbox, an incubation cupboard with interior lighting. The direct lighting of the transparent sample allows any contamination to be identified in seconds. Each beverage-spoiling microorganism, whether it is bacteria, yeast or mould, has a unique appearance. Time-consuming preparation and analysis of Petri dishes is a thing of the past!
