At the blood testing center, potassium ethylenediamine tetraacetate is the "eye" for medical staff to judge the condition. The reason for this is because it can quickly process blood samples and provide reliable basis for disease prevention and diagnosis in biochemical testing projects. As an ideal reagent recommended for clinical use, it is used almost every day, but sometimes it can lead to abnormal blood samples due to problems with the manufacturer's finished products. So in order to avoid such problems, we would like to introduce the usage method to the manufacturer of potassium ethylenediaminetetraacetic acid in the production of finished pipes, in order to reduce errors in operation.
1、 Preparation method
Prepare to weigh the measured potassium ethylenediaminetetraacetic acid powder, dissolve it in deionized water, and continuously stir thoroughly. Note that the powder on the bottle wall needs to be washed down with a washing bottle, and the tools used must not contain any impurities or oil stains. During the dissolution process, pay attention to adding water and leave sufficient volume for the cleaning equipment to avoid excessive volume causing a decrease in the concentration of potassium ethylenediaminetetraacetate. After all is dissolved, just fix the volume, then shake and mix it well. Carefully calculate whether the content of potassium ethylenediaminetetraacetate meets the standard, and confirm that there are no errors before adding it in large quantities.
2、 Add Method
Although it can be divided into machine added and manual added, in order to improve efficiency and reduce labor costs, most manufacturers mainly rely on machines. The specific methods are as follows:
1. Cleaning machine: The machine that adds potassium ethylenediaminetetraacetic acid solution must be sterile, dry, and free of any impurities. Therefore, the pipeline must be cleaned approximately 3 times with deionized water and 80% alcohol, and then dried with hot air.
2. Adjusting machine parameters: Determine the quantity and volume of potassium ethylenediaminetetraacetate that needs to be added based on production indicators, adjust the machine to the appropriate value, first add a small amount, and then add a large number of batches after passing the sampling inspection.
3. Drying: Usually, a hot air blower or drying room is used for drying. The temperature of the hot air drying is between 40 and 80 degrees Celsius, and the drying time should not be too long, about 5 minutes is enough. Pay attention to not blowing too fast to prevent the potassium dioxide solution from blowing out of the tube.
As a professional manufacturer of potassium ethylenediaminetetraacetic acid, Desheng not only has a purity of over 99%, but also has stable performance, simple operation, and is convenient for manufacturers to use when producing finished pipes, with almost no occurrence of improper operation.
