Our blood gas syringes and capillary tube
Aspirating syringe
Pre-barcoded aspirating syringe helps ensure correct patient-sample identification every time when using with a Radiometer blood gas analyser with 1st Automatic.
Self-fill syringe
safePICO self-fill syringe is equiped with an integrated mixing ball and automatic mixing which enhances analytical quality through standardised mixing, without causing haemolysis.
Capillary tube
Our capillary tube is used for low-volume blood gas sampling, mainly on neonates.

Haemolysis in blood samples
Reducing haemolysis in blood samples
Haemolysis is the rupture of the red blood cells, and may happen during sample collection and the following process. The rupture causes the intracellular components of the destroyed red blood cells to be mixed with the plasma. Some of the components, e.g., potassium (K+), are more concentrated in the intracellular compartment than in the plasma phase. Therefore, the reported potassium result will be falsely high.
Clots in blood samples
Air bubbles in the sample
Air bubbles in the sample
Room air contamination of a blood gas sample may alter the values of the sample so that it no longer represents patient's status.
To minimise errors:
- Visually inspect the sample for air bubbles
- Expel any bubbles by gently tapping the sides of the syringe right after sampling and before mixing
- Use arterial blood gas syringes with tip caps that are vented and will allow you to expel air and seal the syringe without getting in contact with blood
Needlestick injuries
Needlestick injuries
Needlestick injury and unwanted contact with patient blood are daily risks for operators collecting blood gas samples.
To minimise risks
- If available, use a safety device that limits the risk of contact with patient blood
- Do not recap needles
- If available, use a needle shield protection device when removal of needles
- Ensure a dedicated procedure for operator safety is established and followed in your facility
