safeCLINITUBES capillary tubes
Minimise the risk of contact with patient blood and match the sample volume requirements of different analyzers
- Made of plastic
- Available with two types of heparin
- Different volumes
The capillary tubes made for neonates
In neonates, capillary blood samples are desirable over other forms of sampling. This is because frequent blood collection from patients with low blood volume can result in anaemia.
safeCLINITUBES—the capillary tubes from Radiometer—are made of plastic, not glass. It empowers you to:
- Minimise the risk of contact with patient blood
- Reduce the risk of preanalytical errors, specifically the formation of clots
- Match the sample volume requirements of different analysers
Our range of safeCLINITUBES capillary tubes
Specialists by blood |
The history of Radiometer as we know it today began in 1954 when Radiometer developed the world’s first commercially available blood gas analyser. Since then, we have refined our blood gas testing knowledge and experience and continue to advance our acute care diagnostic solutions.

Capillary blood sampling in the NICU
56% of all procedures in the neonatal unit are performed using capillary blood samples. Capillary blood sampling is less invasive and requires a smaller amount of blood volume than venipuncture. Compared to other methods of blood sampling that require higher volume, capillary blood sampling reduces the risk of anaemia in NICU patients and avoids the effects of blood volume reduction. [1]
Plastic microcollection devices are recommended for capillary blood sampling. After collecting the sample, these devices need to be capped immediately to prevent room air exposure. Capped samples should be mixed immediately to prevent clots. [1]
