μ-Trac 4200
Compact microbiological analyser for disposable measuring cells based on the impedance principle, direct and indirect measurement options.
| The μ-Trac is a compact system which, with capacity for 21 samples and an economical price tag, meets all those analytical needs which could previously only be met with very costly equipment. Pre-filled measuring cells and a broad medium range avoids the need for a complicated, extensively-equipped micro-biological laboratory and still delivers automatic and well-documented results along with numerous savings. |

Early Results
Many small companies in the food or cosmetics industries outsource their microbiological analyses because they lack an in-house laboratory and the necessary staff. The numbers of analyses required, which has been steadily increasing in recent years, along with the necessary delays due to transport and inadequate capacity of the different services and long waiting times for traditional plate results make it impossible to respond rapidly to cases of contamination. It is therefore often impractical to monitor production processes since products have already been delivered and consumed.
The μ-Trac has indisputable benefits in this area. After a short sample preparation procedure, analysis is carried out directly on site. The classification of results is displayed automatically. Measures can be taken at an early stage of production and/or products can be released earlier for consumption. This allows higher quality and a more flexible shipping strategy.
Taking Measurements
Sample preparation: Direct use of liquid samples or homogenised solid samples. Place measuring cells in incubator, enter sample description via laptop keyboard, the system does everything else. The measuring cell can either be filled with nutrient medium or can be ordered pre-filled. The results are generally available within 24 h. More heavily contaminated products are detected after only a few hours.
Software
The user-friendly software is operated via the integrated laptop computer. The various measurement program displays give information on the measurement determined, the measurement process and the sample status. Exceeded thresholds are indicated in traffic light colours, and are therefore easily recognisable. Once set, measurement conditions or calibration curves are saved and can be referred to for processing individual samples. Extensive data processing options are integrated into the program, data can also be exported to other programs (e.g. MS Excel®, Lotus 1-2-3®), it is possible to connect to LIMS or Q-Software.
