Will the potassium solution of ethylenediaminetetraacetic acid grow bacteria?
When our body experiences uncomfortable symptoms and goes to the hospital for blood routine tests, doctors usually use purple capped vacuum blood collection vessels to collect blood samples to check for abnormalities in white blood cells, red blood cells, and platelets in the blood. The vacuum blood collection vessel with a purple cap actually contains a blood anticoagulant called edta dipotassium , which is suitable for counting and classifying blood cells, as well as detecting blood types and changes in C-reactive protein.
Dipotassium ethylenediaminetetraacetate is a white crystalline powder like chemical substance that is soluble in water and slightly soluble in alcohol. The pH value of the aqueous solution is around 5.3, making it an acidic solution with certain irritation. Therefore, it is necessary to avoid direct contact with the skin. Dipotassium ethylenediaminetetraacetic acid used for vacuum blood collection also needs to be prepared as a solution and evenly sprayed on the inner wall of the blood collection vessel. After collecting blood samples, it is also necessary to mix the two as soon as possible to achieve better anticoagulation of blood.
When producing purple cap blood vessels in large quantities, it is necessary to prepare a large amount of potassium ethylenediaminetetraacetic acid solution. Will there be bacterial growth in the unused solution? The answer is yes, the endless solution of potassium ethylenediaminetetraacetic acid is prone to spoilage and growth when exposed to high temperature and humidity for a long time. Therefore, it is very important to properly store the unused potassium ethylenediaminetetraacetic acid solution.
In theory, we need to follow the principle of ready to use when preparing potassium ethylenediaminetetraacetic acid solution. However, in practical operation, it is difficult to avoid the situation of excessive or insufficient preparation of ethylenediamine tetraacetic acid dipotassium solution. Therefore, when storing unused ethylenediamine tetraacetic acid dipotassium solution, it is necessary to store it at room temperature in a sterile state, and the storage time should not be too long. Desheng is a well-known manufacturer specializing in the production of potassium ethylenediaminetetraacetate. After you purchase the company's products, we will provide detailed instructions on how to use and store them. Welcome to consult and purchase!
