Yellow Cap Serum Separator Tubes: Clot Activator + Gel – The Bright Choice for Busy Labs
Oem Customized Type 3ml-10ml Medical Disposable Vacuum Blood Collection Tube With Yellow Top
Hematology Test Vacuum Blood Collection Tube From China
Vacuum Blood Collection Tube With Additive/non Additive
Product Description:
In the modern laboratory, speed and accuracy depend on instant visual recognition. The traditional gold or speckled red/gold SST tubes are effective, but in high‑volume environments or facilities with multiple similar stopper colors, misidentification can still occur. Our Yellow Top SST introduces a high‑contrast, bright yellow stopper that commands attention, reducing the risk of confusing serum tubes with plasma, coagulation, or other additive tubes.
Inside, the Yellow Top SST delivers the same proven dual‑action performance as the industry standard: a silica clot activator for rapid clotting (20–30 minutes) and an inert polymer gel barrier that forms a permanent seal between serum and cellular components during centrifugation. The result is clear, cell‑free serum ready for direct sampling by automated chemistry and immunoassay analyzers – now packaged in a tube that is impossible to overlook.
