Capillary cap seals the sample 

We have designed our capillary tubes to be free of sharp edges with rounded ends. Our capillary cap helps secure sealing and minimises the risk of blood spillage. The capillary tubes come with a mixing wire and magnet to facilitate mixing of the sample.

Pre-heparinised tubes reduce risk of clotting

Our capillary tubes are preheparinised with dry electrolyte-balanced heparin or high concentration sodium heparin. This reduces the risk of clotting and helps secure reliable results, reducing bias on electrolytes results.
