Description
Haematocrit capillary, 18 µl, is a disposable glass capillary for haematocrit determination, with outer diameter 1,3–1,4 mm and inner diameter 0,5–0,6 mm. Each tube measures 75 mm in length and carries a calibration mark at 60 mm to support consistent filling and reading in routine laboratory work. The capillaries are NH4-heparinised to reduce clotting during sample handling and are identified by a green colour code for quick visual selection at the bench. Designed for single use, they are CE marked in accordance with IVD 98/79 EG and suit clinical and research haematology workflows where reliable micro-volume sampling is required. Supplied in a pack of 5000 pc(s) from manufacturer Hirschmann, these capillaries integrate easily into standard haematocrit centrifuges and related protocols. The defined geometry and heparin treatment help maintain sample integrity from collection through centrifugation, supporting reproducible packed-cell volume measurements in high-throughput settings.
This article is part of Microcentrifuges & mini centrifuges, in Centrifuges.

Questions about HAEMATOCRIT CAPILLARY 18 µl, OD. 1,3-1,4 MM, AMMONIUM HEP
What is this article?
HAEMATOCRIT CAPILLARY 18 µl, OD. 1,3-1,4 MM, AMMONIUM HEP is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Microcentrifuges & mini centrifuges, inside Centrifuges, in Lab instruments.
A microcentrifuge spins 0.2 mL to 2 mL tubes at high force. A mini centrifuge is the small quick-spin for bringing a droplet down from a lid. They are not interchangeable with a 50 mL rotor. The lid lock is part of the safety of the instrument.
A centrifuge separates by density. The rotor spins the sample and the force is reported as a multiple of gravity, not as a raw speed, because the same revolutions per minute are a different force at a different radius. A microcentrifuge takes small tubes. A benchtop or floor model takes larger rotors. The tube, the adapter and the rotor have to be the combination the manufacturer rated. An unbalanced load is how centrifuges fail. Measurement of the related quantities sits with the BIPM.
