Blood Collection Tubes

Blood collection tubes are essential when collecting and transporting blood specimens. The Thomas Scientific collection includes separator tube and lithium heparin tube options. Microcapillary tubes are ideal for the centrifugation of blood samples. Blood collection tubes are an essential component of laboratory equipment for collecting and transporting blood specimens for various laboratory tests. Hematocrit capillary and microcapillary tubes are perfect for collecting samples via capillary action, and measuring the volume percentage of red blood cells. Blood collection tubes provide improved safety and hygiene for blood collection. Following the correct collection and handling procedures by choosing blood collection tubes will ensure accurate and reliable results.

What is a capillary tube used for in a hematocrit?

A capillary tube is used in a hematocrit test to collect, hold, and centrifuge a small blood volume to measure the percentage of red blood cells (RBCs) in the sample. Blood is drawn into the capillary tube, typically through capillary action, and the ends are sealed to prevent spillage.
