Universal ATP Test Swabs for Rapid Cleanliness Detection, ATP Fluorescent Test Swabs

Adenosine Triphosphate (ATP) is a direct source of energy for all kinds of life activities and is found in plant and animal cells, bacteria and food residues.ATP fluorescence assay is a rapid detection technique developed based on the glow of fireflies. That is, in the presence of ATP, recombinant luciferase can catalyse the oxidation of the substrate D-luciferin and emit fluorescence. The number of photons is linearly related to the amount of ATP within a certain range in the presence of an excess of substrates other than ATP. Therefore, the intensity of the fluorescence signal can be measured to know the degree of contamination of the target to be measured by bacteria, food residues, etc.

Domestic ATP Fluorescence Assay Swabs Directions for use:

Leave the swab in refrigerated or frozen condition at room temperature for approximately 10 minutes.
Squeeze the illustration 2 firmly with one hand and pull it out by gently rotating the sealing tube with the other hand (do not pull the sealing tube out directly!) .
Wipe the surface of the object evenly with a cotton tip in a zigzag shape of about 10*10cm2, or take it out quickly after immersing it in the liquid to be tested. When finished, put the sealing tube on.
Fracture the sealing rod and squeeze the illustration 1 so that the solution contained therein flows down the inlet hole, all the way to the cotton tip, and shake the bottom of the swab for about 2 seconds.
Quickly put the swab into the ATP fluorescence detector, press the OK button, and the reading can be taken after 15 or 10 seconds.
Domestic ATP fluorescence detection swab storage and expiration date:
-10℃ to 20℃ storage, try to avoid repeated freezing and thawing of the reagent; for short time storage, it can be stored at 4℃, pay attention to avoid light, sealed storage; validity period of 12 months. Please do not use the reagents that have passed the shelf life.
Domestic ATP fluorescence detection swab (ATP sampler) is suitable for all kinds of domestic and imported fluorescence detector. When used, specimens are collected with pre-moistened ATP swabs. The ATP swabs are moistened with buffer, which helps to extract biomass (ATP) from dry or wet surfaces. The swab contains a reagent that cleaves the cell membrane, releasing intracellular ATP, which reacts with specific enzymes contained in the reagent to produce light, which is then detected by a fluorometer, with the number of micro-organisms being directly proportional to the luminescence value.
ATP fluorescence test swabs using a special type of sample collection and reaction of the integrated rapid detection device, supporting the use of ATP fluorescence detector.
The swabs use the world’s best liquid stabilised reagents, which are more convenient and easy to use, providing more accurate, longer luminescent signal and better reproducible results.
Can be kept refrigerated for long periods of time.
Detects dry surfaces and liquid samples.
Results are available in 15 seconds.
Suitable for all kinds of domestic and imported ATP fluorescence testers.
The price of ATP fluorescence swabs is only half of imported ATP swabs.
Good reproducibility and high reliability of the reaction results, environmentally friendly design.

Precautions:

This reagent needs to be matched with the ATP Fluorescence Detector.
ATP Quickswab contains luciferase, which is gradually inactivated by repeated freezing and thawing. In order to achieve better results, the number of freezing and thawing should not be more than 3 times and should be kept away from light.
For good results, the number of freezing and thawing should not be more than 3 times, and should be kept away from light.
Disposable gloves should be worn to avoid contamination by exogenous ATP.
Do not touch the swabs or swabs during the sampling process and make sure that the swabs are in direct contact with the surface of the object to be measured.
After the reaction of the sample and solution in the swab, it needs to be placed in the fluorometer and read within 60 seconds.
The smear area for standard operation is 10 x 10cm square. For irregular object surfaces, it is important to ensure that each detection for each control point is
A continuous and consistent method is used. The control points should be standardised to take into account the particular structure of the different tables, e.g. table smoothness, instrument seams, recessed areas, cutlery, etc.
seams, instrument seams, recessed areas, the presence of cracks in cutlery (which can easily harbour dirt), etc.
The instrument measures the cleanliness of surfaces with low resolution to the naked eye. Therefore, if the control point to be measured has dirt visible to the naked eye, or if the head of the swab is visibly altered after application, the instrument will not be able to detect the dirt.
If there is visible dirt on the control point to be measured, or if the head of the swab becomes visibly darker after application, stop the operation to avoid wasting the swab.
If excess liquid is present on the surface of the object to be inspected, wait until the liquid has dried slightly before carrying out the test to avoid diluting the reagent. (No special
(no special drying is required).
If you need to test the liquid, you can use a sampler to pick up and add two drops of the sample into the test tube, put it into the test tube and shake it, then mix it with the luminescent reagent.
(Do not swab the liquid directly.)
