With clot activator
The interior of the tube wall is coated with a dry clot activator to accelerate blood clotting.
Range of application: clinical chemistry, immunology, protein electrophoresis, serology, microbiology, toxicology.
The interior of the tube wall is coated with a dry clot activator to accelerate blood clotting. Silicon dioxide is used as a clot activator.
Serum is produced as a result of a two-step biochemical process: blood coagulation (clotting) and clot retraction (shrinking).
Serum is a substance free from clotting factors that contains platelet fragments and metabolic waste products.
Specimen: serum. Clotting time: 10 to 30 minutes. Centrifugation conditions: 1300 g for 10 minutes. Allow the blood to clot completely before centrifugation.
