You Searched For: Capillary Tubes
Capillary tubes are useful for a wide range of scientific and clinical OEM applications. Produced in either glass, plastic, or plastic-coated formats, with heavy or thin walls, capillary tubing can be color coded to designate volume calibration, fill line, or whether they are coated with the anticoagulant heparin. Glass capillary tubes can be used as disposable glass micropipettes or as blood collection tubes, where the heparin prevents blood from clotting when it is drawn.
