What are General Purpose Capillary Tubes?

These tubes enable liquids (most frequently blood) to flow into the tubes against the natural process of gravity, scientifically this is called “capillary action”. They provide precise liquid measurement as the tubes are cut to predetermined lengths, so the exact amount of fluid is easy to calculate. Most frequently these tubes are used in applications such as sample collection, testing and in transfer. Most often made from borosilicate or soda-lime glass, these strong tubes are also sometimes manufactured in plastic or metal.
