Döhler Launches System for Faster Microbiological Contamination Detection

The ready-to-use TransFast-Gel makes it particularly easy to prepare the sample; there is no need to liquefy the agar or keep it warm, both of which take a lot of work.

24 Nov 2010 --- Analysing yeast, moulds or bacteria in water and non-alcoholic beverages usually takes up to 96 hours, but with the TransFast-System from Döhler, the first qualitative results can be seen after just 24 hours.

The Döhler TransFast-System is a new microbiological detection method with significant benefits: it is easy to use, has a short incubation time and can be analysed within seconds. The ready-to-use TransFast-Gel makes it particularly easy to prepare the sample; there is no need to liquefy the agar or keep it warm, both of which take a lot of work. The liquid gel promotes the flow of nutrients to possible contamination sources, allowing contamination to be recognised early.

A further innovation is the back-lit TransFast-Incubation Lightbox, in which the sample tubes are lined up next to each other in front of the light source. The direct lighting of the transparent samples allows any possible contamination to be identified immediately. There is no need for the time-consuming use of Petri dishes, allowing the evaluation time to be reduced by up to 90%.

Döhler also offers many other microbiologically selective nutrient media under the Döhler Microsafety Design (DMD) brand. These allow quality assurance in the production of beer, water and non-alcoholic beverages to be carried out in a simple, consistent, cost-effective and above all reliable way.

The advantages of the TransFast System are listed as follows:
- time span until analysis reduced from 96 hours to 24 hours
- ready-to-use, eliminates preparatory steps
- fast growth of beverage spoiling micro organisms > fast results
- analysis in seconds using backlighting
- early detection of possible contaminants through simple periodical monitoring
