Serum Collection Tubes With Micronized Silica Coating

Vacuette Z Serum Clot Activator Tubes are designed for precise serum separation using a micronized silica coating that promotes rapid and complete clotting. These sterile PET plastic tubes support consistent performance in clinical chemistry, serology, and immunology workflows.

Each Z Serum Clot Activator tube includes a pull-cap top for clean handling and is color-coded for easy visual identification. Available sizes include 2 mL, 4 mL, 6 mL, and 9 mL volumes, allowing compatibility with standard phlebotomy protocols. The PET plastic body resists breakage while offering glass-like clarity, helping lab staff maintain specimen integrity.

This tube series helps laboratories reduce processing delays, minimize sample contamination, and support high-throughput diagnostics. Each format is packaged for single use and offered in box or case quantities to meet high-volume collection needs.
