Fluoride is a weak anticoagulant with a melting point greater than 990°C. When preparing anticoagulant tubes, it can be dried at 100°C. The sodium fluoride powder can effectively inhibit glycolysis and maintain a relatively stable blood sugar concentration, so it is considered an excellent preservative for blood sugar testing.
Sodium fluoride is an inorganic compound, CAS7681-49-4, which is mainly used in blood collection tube additives, phosphating accelerators, agricultural pesticides, sealing materials, preservatives and other fields. The sodium fluoride produced by Desheng is mainly used as an additive for blood collection tubes.

Sodium Fluoride Instructions for Use
Sodium fluoride is an ideal anti-glycolytic agent. Its main function is to inhibit the activity of enzymes involved in glycolysis. The sodium fluoride products inhibit glycolysis by blocking the action of enolase. In daily work. the specimen could be generally preserved for 7 days. Sodium fluoride is often used for blood glucose testing. It should be noted that sodium fluoride may have enzyme inhibitory activity and is not suitable for the situation of enzyme immunoassay. Therefore, it cannot be used for urea enzymatic determination to assay the urea, nor for alkaline phosphatase and starch enzyme assay.
