The vacutainer  is a single-use, plastic, evacuated tube used to obtain high-quality plasma for in vitro diagnostic use. The tube uses a novel mechanical separation technology to obtain plasma from whole blood samples, replacing the need for gel tubes. 

The technology allows the separation of cellular content throughout the centrifugation cycle, reducing centrifugation time from 10 minutes to 3 minutes, and cellular contamination by 50% to 65%.According to the company, the tube is the first to leverage this technology in a clinical setting.

The tube is designed to separate plasma cellular content while also eliminating gel artifacts that can lead to instrument downtime. 

A cleaner plasma sample improves analyte stability, thereby increasing the window for conducting testing. Additionally, the mechanical separator is designed not to absorb hydrophobic drugs, Blood Collection Tube making the tubes suitable for use in therapeutic drug testing.
