4.0 mL Lithium Heparin Tube

The 4 mL PET Lithium Heparin Vacutainer Tube (13 × 75 mm) is engineered for efficient plasma separation and fast turnaround time in clinical chemistry testing. This sterilized vacuum tube contains lithium heparin anticoagulant, which prevents clot formation and maintains plasma stability, making it suitable for a broad range of biochemical analyses.

Manufactured from high-clarity, durable PET and equipped with a light green cap for easy identification, this tube ensures consistent and reliable performance in routine chemistry panels, electrolyte testing, and STAT workflows requiring rapid processing.

1. Inspect tube integrity and check expiration before use.

2. Collect blood using standard venipuncture techniques.

3. Fill tube completely to maintain correct anticoagulant ratio.

4. Gently invert 8–10 times to mix blood with lithium heparin.

5. Centrifuge promptly to obtain plasma for analysis.

6. Proceed with testing according to laboratory protocols.
