Purple Top Blood Collection Tube 3020EK2
The EDTA anti-solution agent of Purple Top Blood Collection Tube works by adsorbing calcium ions (Ca²⁺) in blood samples. Calcium ions are necessary for the activation and reaction of various solution factors during the solution process. EDTA combines with calcium ions to form a stable solution agent, thereby preventing the solution agent reaction from proceeding.

Features:
1.EDTA inhibits the coagulation process by eliminating calcium in the blood.
2.Available in K2 ·EDTA or K3- EDTA.
3.The anticoagulant effect of K3·EDTA is stronger than that of K2-EDTA. K3·EDTA leads to greater red blood cell contraction and generates a greater increase in cell volume at rest.
4. Ensure precise additives through ultrasonic waves and fine coatings.
5. After the test tube is filled with blood, immediately invert it 8 to 10 times to mix and ensure that the specimen is fully anticoagulated
6.Centrifugation: 1100 g for 10 minutes at 18-25°C (Only for EDTA tu beswith separator gel)
7.EDTA anti-AIDS can prevent red blood cell aggregation, which is beneficial to the accuracy of blood type and cross-matching.
8. It cannot be used for projects that require serum testing, such as serum biochemical and immunological serum testing, etc. 9.These items should use blood collection tubes with red or yellow caps.
10.High concentrations of EDTA can cause red blood cells to constrict and white blood cells to aggregate, affecting the morphology of blood cells. Therefore, blood collection should strictly follow the critical line of the blood collection tube to ensure the correct ratio of blood collection to anticoagulant.
