Radiometer offer's a palette of capillary tubes for low-volume PH, blood gas, oximetry and metabolite analysis. The capillary tubes come in a variety of sizes to match the sample-volume requirements of different analyzers.

  • safeCLINITUBES are made of plastic, reducing the risk of breakage.
  • CLINITUBES tubes are made of glass.

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 minimizes the risk of blood spillage. The capillary tubes come with a mixing wire and magnet to facilitate mixing of the sample.

Pre-heparinized tubes reduce risk of clotting

Our capillary tubes are preheparinized 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.
