High Pressure Refillable Cylinders (HPC)
AccuSpan offers a comprehensive range of mixtures supplied in either steel or aluminium high-pressure cylinders to meet your specific needs.
Cylinders can be supplied with either British BS valve, USA CGA or European DIN valve and are manufactured to ISO7866.
Relative mixtures are certified gravimetrically adhering ISO9001:2015 procedures. The weights used to calibrate the balances are traceable to the National Physics Laboratory (NPL). High purity raw materials supplied under a certificate of conformity are used to ensure the final gravimetric filling accuracy.
AccuSpan also can supply certain liquid mixtures.
Please contact us about any specific needs you may have.
