Heparin tube is widely used in blood collection and anticoagulation in clinical biochemical tests and emergency biochemical tests. It is fast on operation and applicable in a wide range of temperature. It will not lead to secondary out-separation of fiber protein. It is also highly caompatable with serum indexes. Normal tube specification: 13x75 13x100 Color: green Volume of normal tube: 1ml, 2ml, 3ml, 4ml, 5ml, 6ml , 7ml Sample validity: less than 6 hr in indoor temperature. Vertical static pressure: more than 8kg/cm2 Ultimate centrifugal turning speed: 5000turn/min. Heparin density: ISO4822 first version (ibid for lithium and sodium) Anti-heparin type: transparent film preparation (dry powder) Mixture requirement: up-side-down shake 5 - 8 times by 90 Note: 1. Most of the indexes are not affected after serum is changed into plasma. 2. The collection amount shall be sufficient as required to avoid the increase of the relative density of heparin which will affect the measurement of calcium and ferment. 3. When blood is collected for 6 hrs, the test result is unlikely to be repeated.
