The Uvasic tube is used with the Hemathix Blood Analyzer for each blood viscosity test. Designed for testing biological fluids, the patented Uvasic tube is disposable and prevents the lab technician from making contact with the specimen.

The calibrated glass capillary is positioned horizontally between riser columns in a U-shape. Driven by gravity, the blood sample equilibrates from one column to the other by moving through the glass capillary, which is calibrated to ensure accuracy. The sweeping deceleration of blood flow as the column heights balance produces a complete viscosity scan.
