Calibration Gas Mixtures

We can supply custom made gas and liquid mixtures for all analytical, detection and process applications in a wide range of container sizes.

Certificate of Composition

All primary and certified mixtures are issued with a certificate of composition, showing a certified shelf life which can be accessed online via the StG website. We also supply, as standard, an extra laminated certificate tied to the valve or guard for our customer's records. StG use a range of specialised internal cylinder treatments to give excellent mixture stability and optimum shelf life.

Quality

All cylinders are supplied with a weather proof body label, thermographically produced to withstand arctic sub-zero temperatures, wet tropical conditions or intense heat as found in the desert regions.

All StG products are traceable to the National Physical Laboratory or UKAS calibrated weights.

If analysis is required we calibrate against UKAS, NPL or NIST gas standards.
