Rapid Microbiology - SyLab BacTrac & μ-Trac
SyLab BacTrac 4300
Rapid Microbiological Analyser
The BacTrac 4300 bacteria tracer rapidly and automatically detects the growth of a wide range of micro-organisms. In recent years the impedance measurement method on which this device is based has proven to be so versatile and robust that it has become the undisputed market leader.
Its innovative measurement method gives the BacTrac the versatility to address a broad range of applications. Two impedance measurements per sample, the M-value (media) and E-value (electrode) can be used individually or in combination to provide the growth profile of sample contaminants.
The BacTrac 4300's electronics and measurement technique provide superior sensitivity to microbial metabolites and allow measurements even in highly selective media.
Rapid Investment Payback
Simplified sample preparation coupled with the elimination of manual plate handling and enumeration improve laboratory sample throughput. In addition, a significant decrease in the exposure of personnel to organisms contributes to laboratory safety. The Bac-Trac 4300's integrated GLP-compliant test result documentation and reporting system facilitates trend analysis, reduces user review time and enhances process control.

BacTrac is expandable: can simultaneously test up to 768 samples in 24 temperature zones.
Easy System Expansion
The BacTrac 4300 system is designed to expand along with your analytical needs. Since differing bacterial groups require different incubation temperatures, we provide the versatility of two independently controllable incubator zones in each BacTrac 4300.
Each zone has 32 sample wells allowing the user to test up to 64 samples simultaneously in two temperature zones. If your testing volume requires even greater capacity, simply connect additional 64 well BacTrac 4300 units as you need them. A maximum of 768 samples can be tested simultaneously in 24 independently controlled incubator zones by linking up to 12 BacTrac 4300 units together to a single control PC.
Flexible Measurement Methods
The ability of the BacTrac 4300 to measure electrode (E-value) or media (M-value) impedance either separately or in combination allows a user to implement a variety of qualitative and quantitative methods and calibrations. Direct impedance measurements on a wide range of bacteria / media combinations can be made without interference from the high salt content of some selective media. Indirect measurement techniques using nested cells permit the rapid detection of yeasts and moulds.
Disposable or Reusable Measurement Cells
The BacTrac 4300 allows you to choose from a range of pre-filled, disposable measurement cells that are ready to use or durable, multi-use glass cells that can be autoclaved.
The Advantages at a Glance
- Efficient screening method.
- Automates traditional culture methods.
- Rapid detection provides an early warning system.

SyLab μ-Trac 4200
Microbiological Analyser
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.
