Grey Blood Tube
(Per Case)

Tubes are silicone coated evacuated tubes with grey color-coded closures. The pre-defined vacuum affords the exact draw volume of the individual tube. The tubes contains additives in concentrations adjusted to the draw volume specified on the tube's label. The choice of the correct type of tube depends on the recommendation for the analytical test method subsequently applied. One order = One case = 1,800 tubes.

Fluoride Grey tubes are used to collect, transport and process blood for testing in clinical laboratories for glucose tolerance tests.

Lavender tubes are intended for collection, transport, and processing of venous blood for testing or serum in a clinical laboratory.
