     Maximum vacuum error ±10%
     Using Instructions: 1.Immediately after the blood collection, gently invert and mix 5-6 times.
                   2.Please pay attention to the blood volume when collecting blood to ensure the accuracy of the test results.

Green top blood tube

Blood specimen collection for clinical biochemistry, emergency biochemistry, and blood rheometry. Little interference to blood components, does not affect the volume of red blood cells, does not cause hemolysis. It has the advantages of fast plasma separation rate and strong compatibility with serum specimens.
Specification: 13×75mm 13×100mm;Routine blood collection: 3ml 4ml 5ml 7ml
    Additive: sodium heparin, lithium heparin
    Limiting centrifugal speed: 5000 rpm
    Maximum vacuum error: ±10%
    Using instructions: 1. Immediately after blood collection, mix at a temperature of 180 ° for 5-6 times.
                  2. Take enough blood. Avoid the determination of calcium by increasing the relative concentration of heparin.
                  3. Heparin anticoagulation should be used within 6 hours, otherwise the blood will coagulate again

Yellow top blood tube

For serum biochemical tests, immunoassays, drug testing, etc. Uniform coating of the coagulant on the tube wall can greatly shorten the blood coagulation time. The imported separation gel is not easy to adsorb the protein in the serum, and the stability is strong. The separation gel after centrifugation solidifies to form a barrier, and the serum and the blood cells are completely separated, thereby effectively preventing the substance exchange between the two and obtaining high quality serum. The results of blood tests are more realistic and increase the rate of serum collection. And can extend the shelf life. Can be directly on the machine, will not block the probe channel.
Blood coagulation time: 10-20 minutes
    Limiting centrifugal speed: 5000 rpm
    Operating environment temperature: 0 ° C -37 ° C
    Maximum vacuum error: ≤10%
    Handling precautions: 1. Immediately after blood collection, 180° gently invert and mix 5-6 times
                  2. In order to better form the colloidal barrier, the blood is completely coagulated and centrifuged for 8-10 minutes.

Orange top blood tube

Collection of blood specimens for biochemistry and immunological examination in medical examinations. The inner wall of the blood collection tube is evenly sprayed with a medicament for preventing wall hanging, and a coagulant is added at the same time, which has the advantages of wide operating temperature range, fast blood coagulation speed, and no secondary appearance of fibrin.
Blood coagulation time: 10-20 minutes
     Limiting centrifugal speed: 5000 rpm
     Operating environment temperature: 0 ° C -37 ° C
     Maximum vacuum error: ±10%
     Coagulation time: When the platelet function is not impaired, the clotting time is ≤5 minutes.
     Handling precautions: 1. Immediately after blood collection, gently invert and mix 5-6 times, be sure to wait for the blood to completely condense.Centrifuge for another 5-10 minutes.
2. When the blood collection does not reach the specified amount of blood collection, remove the residual vacuum in the tube.

Blue top blood tube

For the examination of blood coagulation mechanism, the vacuum blood collection tube with the ratio of anticoagulant to blood sample is 1:9, the anticoagulation ratio is constant at 0.109mol/L, and the ratio precision is high. Because sodium citrate is less toxic, it is also used for blood preservation.
Additive type: sodium citrate (also known as sodium citrate)
  Operating environment temperature: 0 ° C -37 ° C
     Operational notes:1. Immediately after blood collection, mix gently by inversion at 180° for 5-6 times.
  2. Please pay attention to the blood volume when collecting blood to ensure the accuracy of the test results.
  3. When the tube is applied with a soft-connected bi-directional blood collection needle, it should not be collected as the first tube.

Black top blood tube

Type of additive: sodium citrate (sodium citrate)
Maximum vacuum error: ≦5%
    Operational notes:1. Immediately after blood collection, gently invert and mix 5-6 times.
2. Please pay attention to the blood volume when collecting blood to ensure the accuracy of the test results.

Grey top blood tube

Sodium fluoride:Blood sample collection and anticoagulation for detecting blood sugar, glucose tolerance, red blood cell electrophoresis, anti-alkaline red blood protein, sugar hemolysis, etc., due to the addition of inhibitors and special treatment of the inner wall of the test tube, the original state of the blood is maintained for 72 hours. The blood cell metabolism is basically stagnant and so on.
    Limiting centrifugal speed: 5000 rpm
    Maximum vacuum error: ≤5%
    Handling precautions: Since sodium fluoride has a good effect on preventing and controlling blood sugar degradation, it is recommended to gently mix and invert 5-6 times after blood collection.
