Micro Haematocrit Capillary Tubes

Micro Haematocrit Capillary Tubes are quality products that conform to the international standard ISO 12772. The tubes are fire-polished at the colour-coded end to reduce wear on the centrifuge seals. We recommend the colour-coded end to be sealed with our Wax plate. The colour-coding on the tubes and packaging indicates the impregnation of the tube: plain (blue colour), sodium heparin (red colour), ammonium heparin (green colour) and lithium heparin (orange colour). Each heparinised tube contains at least 4-7 IU heparin as prescribed by the standard. The Micro Haematocrit Tubes are also available in plastic with plain, sodium, or ammonium heparin in a volume of ~50 μl. The plastic tubes offer an alternative to glass and can be selected where a plastic option is preferred for handling and safety considerations, without compromising compliance with the standard. The tubes are available in two types of packaging: Dispenser vials of 100 tubes each for hygienic and easy handling; and economy cardboard boxes of 1000 tubes, which reduce transport and handling costs. Special requirements regarding marking, dimensions or impregnation are possible.
