In traditional methods for detecting bactericidal effects, samples are usually taken after sterilization and then inoculated onto bacterial culture plates for further analysis24Hour by hour cultivation, evaluate the effectiveness of sterilization by comparing and observing the growth of bacteria before and after sterilization.
This method is rigorous and accurate, but its biggest drawback is that it takes too much time,48The results obtained after hours cannot make immediate adjustments to the sterilization process, which may result in the sterilization effect not reaching the ideal state.
ATPThe rapid sterilization effect detection method is based onATP(adenosine triphosphate)Principle of Triphosphamide Glycoside Detection..ATPIt is a way of moving in all aspects,plant,bacteria,mold,The energy unit contained in living cells such as yeast. All living microorganisms are rich inATP.Therefore, detectionATP,It can reflect the quantity of all microorganisms. Microorganisms in the sampleATPAfter being extracted, it was mixed with luciferase(Luciferase)And fluorescein(Luciferin)Generate fluorescence under the action,The amount of light andATPdirectly proportional.And the amount of light can beBiotraceThe fluorescence analyzer detected it,The more living microorganisms there are,thenATPThe more, the greater the amount of light generated. Thus achieving the detection of microorganisms in the sample.
Detailed parameters:
3MATPTechnical parameters of fluorescence detector:
The instrument is lightweight and only heavy400Ke, convenient for on-site operation
The detector uses photomultiplier tubes, which have the advantages of being smaller, more sensitive, and faster than photodiodes, and are suitable for weaker light
The detection and reception of signals enable a higher level of true sensitivity to be achieved.
Testing Scope:0—999999RLU
The detection sensitivity has reached10-15mol ATP

The instrument displays the remaining power and charging status
Built in automatic startup check and alarm function
The power on self-test function ensures that during startupATPAll components of the instrument are in normal working condition;
The alarm function informs customers that the instrument is abnormal and in an abnormal working state, in order to quickly identify the problem and troubleshoot it.
240×160Pixel LCD display, screen with backlight function, user can customize backlight duration
Detection chamber/After placing the automatic sensing and alarm function sampling rod into the instrument for testing, if it is not taken out in a timely manner due to busy work, it is likely to forget the residual sampling rod inside (especially the last one tested each time). Therefore, when placing the instrument flat after testing, the solution in the coating rod may leak into the chamber, causing pollution. In mild cases, it may increase the background value of the instrument, and in severe cases, it may affect the detection results of optical components, that is, machine failure. Therefore, this alarm function can warn the operator to take out the coating rod after the testing is completed, and also cultivate good operating habits.
You can download the self edited testing plan to the instrument and conduct the testing according to the plan
