Products Description
Disposable No Additive Blood Collection Tube is specialized containers used for the collection and separation of serum without the introduction of any chemical additives. These tubes play a vital role in medical laboratories and clinical diagnostics by offering a pure and unaltered serum sample that retains its original biological and chemical properties.
Each disposable no additive blood collection tube is internally sterile and vacuum-sealed to ensure consistent blood draw volumes and to minimize external contamination. After blood collection, centrifugation enables the natural separation of serum from clotting elements and blood cells, with no interference from anticoagulants or clot activators. This makes plain tubes particularly suited for biochemical analysis, enzyme assays, hormone detection, infectious disease screening, and immunological testing where unmodified serum is critical for result accuracy.
