How to improve the solubility of potassium ethylenediaminetetraacetic acid

 

The original character of dipotassium Ethylenediaminetetraacetic acid is white powder. When it is used as a blood Anticoagulant to add to the blood collection vessel, it needs to be prepared into a solution and evenly sprayed to the inner wall of the blood collection vessel. After blood collection, it needs to fully mix the blood with dipotassium Ethylenediaminetetraacetic acid to avoid partial or complete coagulation of the blood sample. Therefore, it is very important to prepare Ethylenediaminetetraacetic acid potassium solution evenly and quickly, which also requires high solubility.

 

To understand how to improve the solubility of dipotassium Ethylenediaminetetraacetic acid, first we need to know what factors affect its solubility. Firstly, EDTA dipotassium is composed of two potassium ions (K+) and two EDTA anions (E - or OH -), making it an alkaline compound with higher solubility; In addition, temperature is also an important factor to increase the solubility of Ethylenediaminetetraacetic acid potassium. High temperature will increase the kinetic energy of water molecules and make water molecules interact with EDTA molecules. Therefore, 25 ℃ is a relatively suitable temperature.

 

In the normal temperature environment of 25 ℃, the solubility of Ethylenediaminetetraacetic acid dipotassium produced by Desheng can reach more than 60% (g/ml) in water. Deionized water is mainly used for configuration and dissolution, and Ethylenediaminetetraacetic acid dipotassium powder is added while stirring. During the whole configuration process, first of all, the equipment should be clean and free of oil stains. Second, the amount of water solution should be controlled, and a certain amount of solvent should be left for the Ethylenediaminetetraacetic acid tripotassium powder adhered to the cleaning appliances, To avoid causing a decrease in concentration.

 

Hubei Xindesheng Material Science and Technology Co., Ltd. has been studying the additives for blood collection tubes for nearly 20 years. It has a professional research and development team and advanced production equipment. The process is stable, the difference between batches is small, and the produced dipotassium Ethylenediaminetetraacetic acid has high purity and good solubility. In addition to dipotassium Ethylenediaminetetraacetic acid, there are Anticoagulant such as tripotassium and disodium Ethylenediaminetetraacetic acid, heparin lithium, heparin sodium, as well as serum separating gel, silicating agent, coagulant accelerator, etc. The product range is complete and the quality is reliable.
