Sterile Sodium Citrate 1:9 Blood Collection Coagulation Tubes – 100pcs

These disposable, sterile sodium citrate blood collection tubes are an essential supply for veterinary clinics, labs, and pet animal diagnostics. Available in three sizes — 2ml, 5ml, and 10ml — these light-blue-capped plastic tubes are pre-filled with 3.2% sodium citrate (9NC) at the standard 1:9 anticoagulant-to-blood ratio, ensuring precise, reliable results for coagulation testing and fibrinolytic system analysis.

Made in Mainland China.

Whether you're running PT, APTT, or fibrinogen tests in a professional lab or a veterinary setting, these tubes deliver consistent, accurate performance every time. The exact 1:9 ratio is critical — it prevents misdiagnosis by maintaining the integrity of coagulation factor activity in the blood sample. These tubes are also suitable for short-term blood storage.

Frequently Asked Questions

Q: What is the purpose of the 1:9 sodium citrate ratio in blood collection tubes?

A: The 1:9 ratio (1 part 3.2% sodium citrate to 9 parts blood) is the internationally standardized proportion for coagulation testing. This precise ratio ensures that calcium ions in the blood are properly chelated without over-anticoagulation, preserving the activity of clotting factors for accurate PT, APTT, and fibrinogen test results.

Q: Are these blood collection tubes suitable for use with pets and animals?

A: Yes. These sodium citrate coagulation tubes are designed for use in both human laboratory and veterinary/pet animal diagnostic settings. They are ideal for clinics and labs working with dogs, cats, and other animals that require blood coagulation testing.

Q: How should I choose the right tube size (2ml, 5ml, or 10ml)?

A: Select the tube size based on the volume of blood required for your test. The 2ml tube (13×75mm) is ideal for small samples or pediatric/small animal use; the 5ml tube (13×100mm) is the standard lab size; and the 10ml tube (16×100mm) is best for tests requiring larger sample volumes. Always fill to the marked line to maintain the correct citrate-to-blood ratio.

Q: Are these tubes vacuum (evacuated) or manually filled?

A: These are vacuum blood collection tubes designed for use with standard blood collection needle sets. The built-in vacuum draws the correct blood volume automatically to maintain the 1:9 ratio. Always ensure the vacuum draw is complete before removing the needle.
