The tubes are applicable to blood serum biochemical test, immunization test, and drug test etc. The internal walls are coated with pro-coagulant which and shorten the coagulation time significantly. Using the imported separation gel to prevent the protein in serum from adhesion and maintain a stable status. The centrifuged separation gel is solidified and forming a barrier to separate the serum from blood red cells and stop the exchange of the substances between them. Thus obtain the high quality serum. Color Code: YellowSpecifications: 13x75mm, 13x100mmNormal Sampling Dosage: 2ml, 3ml, 4ml, 5ml, 6mlComplete Coagulation Time: 10-30 MinutesMaximum Centrifugal Speed: 5000turns/min. Operation Temperature: 0-37 CMaximum Vacuum Tolerance: ≤ 10%Attentions: 1. Soon after the blood sampling, turn the tube 180 upside down, shaking and mixing 5-6 times. 2. In order to help the gel to form a barrier, only can centrifuge the blood 8-10 minutes till the blood coagulated completely. Company: Jiangsu Kangjian Medical Apparatus Co., Ltd.
