E. coli tester / E. coli tester

Model: ADU1-TOGS 9000

(Quantitative) for a single analyzer is a microprocessor-controlled temperature sample spectra with the instrument, its Aquasure 3000 adds new features, the use of fluorescence spectrometer, colorimeter, turbidimeter quantitative analysis of the sample, Even in remote areas can also be used without a computer, and the large capacity of information and data storage.



And compared to the conventional spectrophotometric method, our "growth time spectrophotometer" (TOGS) spectrometer instrument using the heated container in the growth of microorganisms in the optical signal detection, all of these conditions, all automatically without interference completed.

Determination of E. coli with the existing MF method, the standard MPN MPN method and quantitative comparison of plate has the following advantages:



1. Without dilution



2. With a large dynamic linear range (LLDR) -5 orders of magnitude. Samples can be detected in 100ml 1CFU (bacterial colonies) -100 CFU, and no dilution or other sample preparation steps



3. In the 13 hours to complete the testing and reporting



4. Reduce the false positive and false negative results occur



5. Readily available for each individual sample temperature monitoring



6. Because with the goal of enhancing the fluorescence signal proportional to the growth of microorganisms, so the fluorescence signal from other sources will not cause interference, and interference signal throughout the entire testing process



7. Medium turbidity samples can also be the detection of E. coli



8. Sample preparation in one step, human error can be ignored



9. Continuous operation



10. Test could one day or any time within one week



11. Real-time monitoring testing process - without requiring the detection of color changes during the observations. The visual detection limit of the independent agents to avoid the appearance of false positive results



12. No correction



○ no moving parts

○ quantitative rather than signal sensitivity is based on the time

○ sensitivity based on signal detection time



13. In each test the initial auto-zero



14. No drift - constant temperature curve throughout the entire testing process



15. Growth curve is drawn based on the growth time, while the curve starting with the environment at a constant temperature is proportional to the initial concentration of microorganisms
