9NC Coagulation Sodium Citrate 3.2% Tubes
The 9NC Coagulation Tube containing 3.2% trisodium citrate is specifically designed for use in clinical chemistry testsand is manufactured by TTT World to meet the highest medical standards. These vacuum-sealed, single-use tubes are produced in various volumes and can be optionally labeled with pre-barcoded stickers for improved traceability.

Available Volumes
These tubes are manufactured in 12 different volume options to meet clinical needs:
0 ml
8 ml
0 ml
5 ml
7 ml

Each tube features a blue cap and is prepared with precise proportions of trisodium citrate, ensuring a blood-to-additive ratio of 9:1 for optimal test accuracy.
Applications
These tubes are commonly used for:
Routine coagulation testing in chemistry labs
Manual or automated ESR (erythrocyte sedimentation rate) testing
Any blood draw procedure requiring anticoagulated plasma
Citrate tubes are available in two formulations: 3.2% and 3.8%, both using the dihydrate form of sodium citrate. The Clinical Laboratory Standards Institute (CLSI) recommends using either of these formulations depending on the test specifications.
Why Tube Quality Matters
Variation in manufacturing quality can lead to inconsistent test results. TTT World prioritizes product reliability and precision to ensure dependable diagnostics. Not all tubes are created equal, and selecting a reputable manufacturer directly influences the accuracy of diagnostic outcomes.
Importance of Quality in Medical Devices
The entire lifecycle of a medical product—from manufacturing to storage and final usage—directly impacts the validity of test results. Even small deviations in formulation can lead to misdiagnosis and incorrect treatment. For this reason, TTT World ensures every product is designed, produced, and distributed under strict quality assurance protocols.
Trusted by both public and private sector healthcare institutions, TTT World is known for its reliable service and commitment to health and safety.
Essential Considerations When Using Blood Collection Tubes
A sample with visible clotting is invalid for testing
After drawing blood, invert the tube 3–4 times to mix (do not shake)
Expired tubes should never be used
Improper handling during transfer or testing can also invalidate results
Patients must follow pre-test preparation guidelines (e.g., fasting, avoiding alcohol, physical rest)
Each step in handling—from collection to centrifugation—must be executed with precision. TTT World supports this process with both high-quality products and ongoing training for partner laboratories.
Supporting Excellence in Healthcare
As part of our mission to advance healthcare standards, TTT World not only manufactures superior blood collection tubes, but also provides training and implementation support for their use in clinical settings. This ensures that all affiliated institutions—both public and private—can perform tests correctly and efficiently.
Through this proactive approach, we contribute significantly to Turkey’s leadership in medical innovation. All products are produced domestically, with biocompatible materials and certification from the Turkish Standards Institution.
With every new development, TTT World continues to lead with integrity, innovation, and unwavering commitment to quality healthcare.
