Capillary tubes for microhaematocrits are used for the centrifugation of blood samples.
Heparinized capillaries should be used when the samples are not immediately sealed with wax and centrifuged.
The heparinized coating delays the clotting of the blood. The heparinization is applied as a thin, homogenous coating on the tube.
This enhances the immediate dissolving of the heparin in the blood and prevents agglutination.

액체 속에 폭이 좁고 긴 관을 넣었을 때, 관 내부의 액체 표면이 외부의 표면보다 높거나 낮아지는 현상. 액체의 응집력과 관과 액체 사이의 부착력에 의한 현상이다. 식물의 뿌리에서 무기양분과 물을 흡수하는 것을 이것으로 설명할 수 있다.
