Description
Microhaematocrit capillary tubes 75 µl are sodium-heparinised capillaries intended for haematocrit determinations and related micro-volume blood analysis. Each tube measures approximately 75 mm ±0,5 mm in length, with an inner diameter of 1,1–1,2 mm and an outer diameter of 1,5–1,6 mm, providing consistent sample uptake and handling during centrifugation. The tubes are suitable for applications conforming to EU Regulation 2017/746 on in-vitro diagnostic medical devices (IVDR). They carry the CE mark and are supplied with a recommended expiry date plus batch number to ensure comprehensive information and full traceability. Available from manufacturer Marienfeld, the product is packed as 100 pieces in a convenient dispenser tube, with 10 tubes per carton, supporting orderly laboratory workflows. The sodium-heparin coating helps maintain sample integrity by minimising clotting, making these capillaries a practical choice for clinical diagnostics, research laboratories and routine haematology procedures requiring precise microhaematocrit measurement.

Questions about Microhaematocrit capillary tubes 75 µl,
What is this article?
Microhaematocrit capillary tubes 75 µl, is the article on this page. Luminix Health distributes Marienfeld 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.
