Chlorine Gas Cylinders and Sizes for Industrial Use

Standard industrial gas cylinders are typically designated by weight or volume capacity. For chlorine specifically, SpecGas offers 40 lb., 70 lb., and 100 lb. cylinders. These correspond to both disposable steel and refillable aluminum or steel cylinder types, depending on whether the application requires single-use or returnable container options.

SpecGas chlorine gas mixtures are available in concentrations ranging from 0.5 ppm up to 10%. This covers low PPM ranges (1–100 ppm) suitable for detector calibration and workplace exposure monitoring, as well as mid-PPM to percent-level concentrations for process and industrial manufacturing applications.

Chlorine gas mixtures from SpecGas are available balanced with pure nitrogen gas or zero air. Inert balance gases are selected to ensure mixture stability and minimize reactivity. The choice of balance gas depends on the specific application, detector type being calibrated, and whether oxidizing or inert background conditions are required.

Yes. SpecGas chlorine calibration gases are specifically formulated for bump testing and calibration of Cl₂ detectors and multi-gas monitors from leading manufacturers including MSA, Dräger, Honeywell BW, Industrial Scientific, RKI, Crowcon, GfG, and RAE Systems. All mixtures are NIST traceable for reliable calibration accuracy.

Chlorine is a highly toxic, reactive gas subject to strict OSHA and NIOSH regulations. OSHA sets a PEL ceiling of 1 ppm, and NIOSH recommends a STEL of 0.5 ppm. Proper gas detection systems, stainless steel or aluminum tubing and regulators, and adherence to CDC NIOSH guidelines are required for safe handling and workplace compliance.

SpecGas employs a proprietary internal cylinder treatment process developed through decades of specialty gas R&D. This treatment conditions the cylinder walls to reduce reactivity and gas adsorption, resulting in stable chlorine mixtures with longer shelf life. Combined with NIST-traceable blending, this ensures concentration accuracy is maintained throughout the cylinder's usable life.
