These heparinized glass tubes support reliable capillary sampling where only small blood volumes are available — pediatric draws, fingerstick collections, and rapid packed-cell-volume testing.\u003c\/p\u003e\n\u003cp\u003eThe HemoCue StatSpin Capillary Blood Collection Tubes (HT9H-10) are 40 mm glass micro-hematocrit tubes with a 9 µL capacity and an ammonium heparin additive that prevents clotting without altering cell morphology. The red band identifies the heparinized coating, and the clear tube body allows the technician to visually confirm complete, bubble-free fill before centrifugation. Supplied without a closure and non-sterile, they are intended for standard laboratory micro-hematocrit workflows rather than sterile venous collection.\u003c\/p\u003e\n\u003cp\u003eLaboratory buyers typically ask three things about micro-hematocrit tubes: the additive, the fill volume, and whether they're heparinized. StatSpin tubes answer all three — ammonium heparin, 9 µL, and pre-coated for anticoagulation — which is why they pair naturally with StatSpin-style micro-centrifuges for fast spin-down and consistent hematocrit reads. Ammonium heparin is the preferred anticoagulant for hematocrit work because it minimizes cell shrinkage that can skew the packed-cell-volume result.\u003c\/p\u003e\n\u003cp\u003eWhen ordering, confirm the tube length and additive match your centrifuge and reading protocol, and stock adequate quantities for your daily testing volume, since these are single-use consumables.
