Notes:
Only use plastic capillary tubes on micro-hematocrit centrifuge rotors that support the entire length of the tube. If the rotor only supports the tubes at two points, the tubes will bend and the sample will be lost. For rotors that support two points, use our glass capillary tubes.
If collecting anti-coagulated blood from a blood collection tube, use a plain capillary tube.
If collecting by finger stick from a patient or when using untreated blood, use capillary tubes that are treated with an anticoagulant (heparin).
