Frequently Asked Questions

How long do calibration gas cylinders last before expiring?

Many single-gas calibration cylinders have a defined shelf life of three years from the manufacturing date, with multi-gas cylinders often having a 1-year shelf life. Always check the specific expiration date printed on your cylinder label.

What happens if I use expired calibration specialty gases?

Expired calibration gas may have altered concentrations due to chemical degradation or cylinder permeation, leading to incorrect sensor calibration and adjustment. This can cause false readings and potentially dangerous situations where gas hazards such as carbon monoxide go undetected.

How often should I calibrate my gas detection tools?

Many manufacturers recommend bump testing before use. For full calibration, always follow your instrument manufacturer's guidelines and local regulatory requirements for accuracy.

Can I dispose of empty calibration gas cylinders in regular trash?

No, empty calibration gas cylinders may be returned to the supplier or disposed of through proper hazardous waste channels. Many laboratories and suppliers offer cylinder return programs for safe disposal and recycling under a return agreement.

For empty cylinders, an alternative is to either remove the check valve from the top of the cylinder or to drill holes in the bottom or sides to render the cylinder harmless. Recycle with other metal waste. We offer a cylinder valve removal tool that works on many types of cylinders.

Are there shipping restrictions for calibration gas cylinders?

Yes, calibration gas cylinders are considered hazardous materials and must be shipped via ground transportation with proper DOT labeling. Air shipping is typically prohibited, so plan accordingly for delivery timelines to remote locations.
