Hawksley micro haematocrit capillary tubes are high-quality products that conform to ISO 12772 and are supplied colour-coded for easy differentiation. The tubes are firepolished at the colour-coded end to reduce wear on the centrifuge seals. We recommend the colour-coded end to be sealed with Hawksley Cristaseal. Each heparinised tube contains at least 4-7 IU heparin as prescribed by the standard. Hawksley Micro Haematocrit tubes are also available upon request in plastic with plain, sodium or ammonium heparin in a volume of ~75 μl. The plastic tube provides the same effect as the glass tube, but the possibility of contamination with the plastic tube is reduced due to breakage with no compromise in accuracy.
- Tubes are supplied fire polished to reduce wear on the centrifuge seals
- Uniform heparisation assured
Supplied in dispenser vials containing 100 tubes each for hygienic, easy handling or in economy cardboard boxes to reduce transport and handling costs.
