MaxiLab vacuum blood collection tubes with 3.8% sodium citrate (0.129 mol/L) are specifically designed for collecting venous blood samples for coagulation studies. The 9:1 blood-to-anticoagulant ratio is crucial for accurate results. Insufficient citrate leads to microclot formation and/or sample coagulation, while excess citrate can distort results by binding calcium in reagents. These tubes are 13x75mm, 2.7ml capacity, and packaged in quantities of 100. Expiry date: 03/2025.
