Vacuette® Z Serum Sep Clot Activator Blood Collection Tube, 3.5 mL | Greiner Bio-One (454228P)

When accurate serum chemistry results depend on clean separation, lab professionals reach for the Greiner Bio-One Vacuette® Z Serum Sep Clot Activator Tube. Engineered for venous blood collection, this gold-capped PET tube combines a clot activator with a separating gel to deliver consistently clear, high-quality serum — draw after draw, patient after patient.

How It Works

The Vacuette® Z Serum Sep tube contains a clot activator and separator gel additive that works in two stages. First, the clot activator accelerates the natural clotting process, reducing wait time before centrifugation. Then, during centrifugation, the separating gel migrates to the interface between the serum and the clot, forming a stable, physical barrier that keeps the serum cleanly separated from fibrin and cellular components. The result is a pristine serum sample ready for analysis — with no risk of re-mixing during transport or storage.

Built for the Modern Clinical Lab

Constructed from durable polyethylene terephthalate (PET), these tubes are shatter-resistant and lightweight — a practical advantage in high-throughput environments where safety and efficiency go hand in hand. The gold pull cap provides a clear visual cue for tube identification, helping phlebotomists and lab techs quickly confirm the correct tube type during collection and processing.
