Laboratory gas cylinder (or standard gas cylinder) is a container of high-precision standard gases. Applications such as handheld gas detector calibration and fixed gas detectors often use small cylinder, with a compressed air capacity of about 10 to 100L. Applications in industrial systems such as gas monitoring stations and industrial lines often use large gas cans with a gas capacity of up to 8-900L.
Laboratory gas cylinder are usually classified by normal size, internal standard gas mixture type or standard gas properties (Reaction/non-reaction).
TES Industry supplies Calgaz standard gases with 2 factories in the US and UK.
