Calibration gas/non-refillable cylinder

Calibration gas cylinders contain precise mixtures of gases like CO₂, O₂, or N₂ in sealed containers, designed to verify the accuracy of medical devices such as anaesthesia machines, blood gas analysers, or patient monitors. Clinically, they ensure devices measure gas concentrations correctly, helping maintain patient safety during procedures or diagnostics by confirming reliable performance before use.

These devices are typically reusable until their gas supply is depleted and are regulated based on their intended use and potential risk. They may fall under specific safety standards depending on the jurisdiction, with requirements covering gas purity, labelling, and handling to prevent misuse or contamination.
