3.0 mL Plain (No Additive) Tube

The 3 mL PET Plain Vacutainer Tube (13 × 75 mm) is designed for the safe and efficient collection of blood samples for serum preparation in procedures where no additives are required. This sterilized vacuum tube features an easily identifiable red cap and supports natural clot formation, helping produce clear, high-quality serum for accurate and reliable laboratory analysis.

It is suitable for a wide range of clinical chemistry, serology, immunology, and routine diagnostic tests. The controlled vacuum design supports consistent blood collection, while the secure cap helps reduce the risk of leakage and contamination during handling and transportation.

Manufactured from high-quality PET material, the tube offers excellent durability, break resistance, chemical stability, and clear sample visibility. Its practical label area allows convenient recording of patient and sample information, making it suitable for everyday use in hospitals, clinics, diagnostic laboratories, and blood collection centers.

1. Verify the tube type, capacity, packaging, and expiration date before use.
2. Do not use the tube if it is damaged, contaminated, leaking, or has lost its vacuum.
3. Label the tube with the patient’s details, collection date, and time.
4. Perform hand hygiene, wear appropriate protective equipment, and prepare the collection site.
5. Connect the tube to a compatible holder and collect blood using the standard venipuncture procedure.
6. Allow the tube to fill completely until the required volume is reached.
7. Keep the tube upright and allow the sample to clot naturally for 20–30 minutes.
8. Do not shake the tube, as this may cause hemolysis and affect the results.
9. Centrifuge according to the approved laboratory guidelines to separate the serum.
10. Use the serum promptly or store it under the conditions required for the intended test.
11. Dispose of the used tube and collection materials in approved biohazard containers.
