<p>Bacteria detection instruments are commonly known as atp fluorescence detection, which is mainly based on the principle of firefly luminescence, using the luciferase-luciferin system "to quickly detect adenosine triphosphate (ATP), adenosine triphosphate (ATP) widely exists in various organisms, is a special kind of biological cells The free energy carrier is used to store and transfer chemical energy, and sometimes constitutes a direct source of energy for all life activities.</p><p><br></p><p>The reaction principle of detection in the bacteria detection instrument:</p><p><br></p><p>The ATP biofluorescence method actually uses a biochemical reaction, that is, luciferin and oxygen react with ATP under the catalysis of Mg2 + and luciferase, which converts chemical energy into light energy, producing fluorescence at a wavelength of 560 nm, while in other reactions In the case of excess, the fluorescence intensity is proportional to the ATP content, so the ATP content in the sample can be indirectly determined by measuring the fluorescence intensity.</p><p><br></p><p>When the bacteria die, under the action of enzymes in the cell, ATP can be broken down quickly and can release a lot of energy. Therefore, by measuring the content of ATP in a sample containing biological factors, the condition of microorganisms in the sample can be reflected indirectly.</p><p><br></p><p><a href="https://www.smileksmedical.com/atp-bacteria-meter" rel="noopener noreferrer" target="_blank">Bacteria testing equipment</a></p><p>In recent years, in the evaluation and testing of the cleaning quality of medical devices and various items, the ATP biofluorescence method has been widely used as a rapid on-site detection method for on-site cleaning or disinfection.</p><p><br></p><p>Bacteria detection instruments are widely used and can be used in: food, medical and health, pharmaceutical, daily chemical, papermaking, industrial water treatment, national defense and environmental protection, water administration, customs entry and exit quarantine and other law enforcement departments and other industries.</p><p><br></p><p>Especially in the field of food safety, bacteria testing equipment has become an indispensable testing equipment for food and drug supervision and management at all levels. It is mainly used for the detection of food processing appliances, employees, food processing environment, microbiological and hygienic status of food processing raw materials.</p><p><br></p><p>The handheld bacteria detection instrument can be quickly used for on-site hygiene testing. The main steps are:</p><p><br></p><p>1. Turn on the machine, click on the test, the instrument prompts "put tester" to enter the test interface;</p><p><br></p><p>2. Remove the swab from the refrigerator, leave it for 10-15 minutes, and use it after returning to room temperature;</p><p><br></p><p>3. Remove the swab from the sleeve, pinch the connector with one hand, and wipe the surface of the object, inclined 45 °, 10 × 10 cm surface;</p><p><br></p><p>4. Insert the collector back into the casing;</p><p><br></p><p>5. Squeeze the connector with one hand and the upper part of the capsule with one hand and bend it back and forth until the valve is broken;</p><p><br></p><p>6. Squeeze the swab head 3 times, so that all the liquid in the swab head is squeezed out;</p><p><br></p><p>7. Squeeze the swab head, shake the swab down 5 times, and insert the swab into the instrument immediately.</p><p><br></p><p>8. Click Test, and the test result will be displayed after 15S.
