The Greiner Bio-One VACUETTE Venous Blood Collection Tube is specifically designed for the precise and reliable collection of venous whole blood for glucose determination. Its optimized ratio of additives, including sodium fluoride to inhibit glycolysis and potassium oxalate to prevent clotting, ensures accurate glucose measurements. Key features include a clot activator for rapid sample processing, a vacuum technology for complete and gentle filling, a serum barrier gel for easy specimen handling, and a clear tube for visual inspection. The leak-proof closure prevents contamination and maintains sample integrity. This tube facilitates fast and efficient sample collection and meets industry standards for blood collection tubes. Its applications extend to glucose determination in clinical chemistry, diabetes management, and research, as well as for monitoring glucose levels in patients with diabetes or hypoglycemia, and for screening for gestational diabetes.
