No Additive Tube – Red Closure Vacuum Blood Collection

The no additive tube emphasizes safe, chemical-free blood collection with vacuum-assisted filling and clear sample visibility. Its additive-free design ensures reliable and accurate laboratory results.

The tube’s vacuum system allows consistent blood draw, reducing user error. High-quality inert materials prevent chemical interaction, ensuring the sample remains unaltered. Red closure color provides clear identification, distinguishing it from other tube types.

Additive-free for unmodified blood sample collection.
Vacuum-assisted filling ensures consistent volume.
Chemically inert materials for accurate downstream testing.
Red closure for easy visual identification.
Transparent tube body allows visual inspection of samples.
Compatible with centrifugation, storage, and transport.
Multiple sizes for different collection needs.
Safe handling reduces contamination and hemolysis risk.
Efficient labeling and tracking in multi-sample workflows.

Its combination of additive-free design, vacuum-assisted filling, and red closure makes the tube suitable for clinical, research, and laboratory workflows requiring precise and reliable blood samples.
