Vacutainer PST Tubes

Vacutainer® PST™ Tubes contain spray-coated lithium heparin (see table for concentration) and a polymer gel that forms a physical barrier between serum or plasma and blood cells during centrifugation. As a result, turnaround time is much faster than with clotting separation techniques.

Plastic tubes have a paper label and light green Hemogard™ aerosol-shielding closure. 

Key Features:

• For chemistry determinations requiring plasma separation
• No need to wait for a clot to form – ideal for STAT procedures and for patients on anticoagulant therapy
