Vacuette® Blood Collection Tube – 3.5 mL Serum Separator, Gold Cap (SKU: 454228P)

Description

The Vacuette® Blood Collection Tube (454228P) from Greiner Bio-One is a sterile plastic evacuated tube designed for the collection and separation of serum samples. With a 3.5 mL draw volume, it contains a clot activator and an inert gel separator commonly used in clinical chemistry, serology, and immunology testing.

Manufactured from virtually unbreakable PET plastic, this tube provides a safer alternative to glass. After centrifugation, the separating gel forms a stable barrier between serum and the clot, preserving sample integrity and stability during transport and storage for up to 48 hours under appropriate conditions.

Best Practices for Use and Maintenance

• Ensure tubes are filled to the nominal volume to maintain correct additive-to-blood ratio

• Do not re-centrifuge SST tubes once the gel barrier has formed, as this may affect analyte stability
