BacTrac 4300 mikrobiológiai impedancia analizátor
With 64 individual measurement positions and 2 different temperature zones per instrument BacTrac can deal with almost all tasks the microbiologist is familiar with from the classical agar plate.
- The BacTrac measuring technology is based on the proprietary patented Impedance Splitting Technology thus enabling the enourmous flexibility of the technology.
- The BacTrac 4300 is user friendly and is ideally suited to the challenges posed by long-term use. The individual measurement positions can be used independently whenever samples are available to be tested. Newly inserted samples will be recognized and analysed automatically according to the parameters set by the user.
- The entire measuring cycle is automatic and the results are permanently recorded to a central database. Barcode readers and a central LIMS can be connected. The BacWin operation and evaluation software is easy to understand and operate.
- The BacTrac techology is an internationaly highly accepted and proven technology. It is successfully in operation in food and food ingredients, water, as well as pharamceutical- and cosmetics industries. It also plays a leading role in the official food hygiene monitoring in various countries.
- With BacTrac almost all the microbiological routine applications will be covered. It can be used for sterility testing, TAMC enumeration as well as testing for index and indicator microbes and to detect microbial pathogens. Thus it is the most versatile automated rapid method currently available on the market.
- The scope of applications is not limited to any matrix and therefore users can refer to a wide catalogue of routine protocols.
Measurement principle
Microorganisms are detected in real time via the decrease of the impedance in an AC field. Any impedance change caused by the microbial metabolism is detected.
In the BacTrac devices a proprietary impedance technology is employed. Usind this technology a standard impedance signal ( Media Impedance = M- value) is registered as the reuslt of microbial growth.
During the growth of microbes low- or non charged nutrient molecules are metabolised. This break down of nutrients generates small and highly charged metabolites. The later will result in a change of the impedance of the nutrient media that is registered by the instrument.
The more microbes are present in the sample the sooner results will be available.
Comprises BacMonitor and BacEval measuring and data evaluation software for Windows 7, WIN-8.1 and WIN-10. Traditional Windows menu functionality is easy to understand and operate without extensive training.
Real Time Results - Color Coded Alerts
- Time already expired from the start of the measurement is displayed in the form of a pie chart for every position.
- For ongoing measurements the pie chart appears in blue
- As soon as the developing growth signal will reach the threshold, detection time will be recorded. If the color code alert mode has been activated the chart will turn the color to red or yellow depending on the limits defined for the individual position. Negative samples or those with results within specification will be marked green.
Database Functions
