Application of EDTA dipotassium
1. Additive of vacuum blood collection: EDTA-2K can chelate with calcium ion in blood, so as to prevent blood coagulation, with fast dissolution and good anticoagulant effect. When using, it should be noted that: due to the validity period of the blood collection tube is two years, when the use environment changes slightly, such as temperature change, water is easy to evaporate to the tube wall (especially the water in the solvent of plastic pet tube can seep through the tube wall and leak out), resulting in EDTA-2K crystal in the tube quickly. When taking blood from the crystallized EDTA-2K blood collection tube, the regulation is reversed for at least 8 times Second, the crystalline EDTA-2K can be fully dissolved and mixed in the blood. If the action is a little big, the red blood cells will be destroyed and hemolyzed, and the platelets will be aggregated, adhered and broken.
2. Preparation of deodorant: according to the mass fraction, it includes the following substances: acid salt, ammonia, urotropine, ethylenediamine tetraacetic acid dipotassium, isobutanolamine and water.
3. Used as complexing agent in liquid phase analysis: for example, in a tetrabutylammonium bisulfate buffer salt system for liquid chromatography detection, the solvent is water, the solute includes tetrabutylammonium bisulfate and buffer ion pair, the buffer ion pair is composed of potassium dihydrogen phosphate and phosphoric acid, the solute also includes complexing agent, and EDTA-2K is preferred as complexing agent.
4. Preparation of metal polishing agent. The main components of polishing agent are: potassium ethylenediamine tetraacetate, trisodium phosphate, dibutyl phthalate, sodium silicate, inorganic acid, dicarboxylic acid compound, tetrameric ricinoleate, biological buffer, stabilizer, water-soluble surfactant and water. The polishing agent can effectively remove the impurities on the metal surface.
Desheng technology company specializes in the R & D, production and sales of vascular additives, in vitro diagnostic reagents, buffers, luminescent substrates, enzyme preparations, antigen and antibody. EDTA dipotassium is the advantage product of the company.
