EDTA K2 vacuum blood collection tube EDTA tubes CAS 25102-12-9
EDTA K2, also known as dipotassium ethylenediaminetetraacetic acid, with a CAS number of 25102-12-9, is widely used in blood collection tubes as an anticoagulant. Its principle of action is that EDTA is close to calcium ions in the blood and complexes with calcium ions , to inactivate prothrombin and prevent blood clotting.
After anticoagulant treatment, the biochemical indicators of the blood sample are closer to the physiological level, which is conducive to more accurate test results and prolongs the storage time of the blood sample. Next, I will introduce EDTA K2 to you in detail.

Application of EDTA K2
Because EDTA has a protective effect on the cellular components in the blood, does not interfere with the count and size of white blood cells, and can prevent platelet aggregation, it is suitable for general blood tests. However, it should be noted that it has anticoagulant effect and is not suitable for coagulation detection experiments. The ability to complex calcium ions is also not suitable for the determination of calcium ions, sodium ions, and iron ions.
Performance of EDTA K2
The appearance of EDTA K2 is white crystalline powder, odorless, soluble in water and easy to absorb moisture.It’s main content is as high as 99% and the molecular weight is 404.6.The pH value of EDTA K2 solution is between 4.8±1.What’s more, it’s solubility in water is higher than 60%, and stable at room temperature.
Notes for EDTA K2:
1. When EDTA K2 is prepared as anticoagulant for blood collection tubes, medical staff should invert it 5-8 times as soon as possible after blood collection to prevent the formation of tiny blood clots in order to fully anticoagulate. Especially when the blood collection temperature is higher than 25 degrees, the blood must be fully exposed to EDTA K2, otherwise it will easily lead to insufficient coagulation.
2. Since EDTA salt is not an irreversible anticoagulant, the test should be completed within one day after blood collection to avoid problems with the test results.
3. When using EDTA K2 for anticoagulation, it is necessary to control the amount added. Too much content may cause changes in the shape of blood cells.
4. When EDTA K2 has foreign matter, abnormal color and smell, or exceeds the expiration date, it should not be used. If it is accidentally spilled on the skin, rinse it with plenty of water and do not touch it directly with your hands.
EDTA K2 preservation:
Due to the performance of EDTA K2, it is easy to be affected by moisture. As a powder, it should be sealed and stored in a dry and cool place. The prepared solution can be stored in a sealed container at room temperature.
Desheng Biochemical is committed to the production of blood collection tube additives, the main content is as high as 99%, and the performance is stable.
