Sodium citrate PET (plasma separator tube) tubes are used in blood collection for various laboratory tests, particularly those requiring plasma. Sodium citrate is an anticoagulant commonly used to prevent blood clotting by binding with calcium ions in the blood. These tubes typically contain a predetermined amount of sodium citrate solution, which ensures proper blood-to-anticoagulant ratio for accurate test results.Our tubes come in different sizes and accommodate 2 mL sample capacity for testing and storage.
