Micro-haematocrit Capillary Tubes with Heparin for Blood Tests

Manufactured from high quality EU glass of the Marienfeld Superior brand.

Heparinized with sodium (80 iu/ml ± 30 %). Approved for in-vitro diagnostic applications according to IVD 98/79/Ec: with CE marking, best-before date and batch number for general information and traceability

The color-coded end is fire-polished to reduce centrifuge wear for single use.

Micro-haematocrit capillary tubes are used for blood collection and centrifugation. Close the tests afterwards with wax filling and centrifuge. If this is not possible, sodium heparinized capillaries are recommended to delay blood clotting. Sodium heparinization is applied as a thin, homogeneous layer in the tube. This promotes the immediate dissolution of the heparin in the blood and prevents coagulation.
