Ensure accurate and reliable glucose, lactate, and glycosylated hemoglobin results with our high-quality 2ml vacuum blood collection tubes. Each tube contains sodium fluoride and potassium oxalate, powerful stabilizers that effectively inhibit glycolysis for up to 24 hours at room temperature. These anticoagulants work by binding calcium ions (Ca2+), preventing the breakdown of glucose into pyruvate and lactate. Sodium fluoride specifically inhibits key enzymes in the glycolytic pathway, such as the conversion of phosphoglycerate to phosphoenolpyruvate.
After collection, gently invert the tube 5-8 times to thoroughly mix the sample. Exercise caution, as tubes containing sodium fluoride are prone to hemolysis. Centrifuge immediately after mixing at 1300G for 10 minutes. It's crucial to fill the tube to the indicated level; insufficient sample volume can lead to excess oxalate, potentially causing erythrocyte destruction and hemoglobin release.
Our tubes are packaged in protective, sealed trays of 100 for convenient handling and to maintain sterility. Expiration date: 02/2026.
