Anyone here use Matheson gas?

Just wondering if anyone here has any experience using matheson instrument grade butane&propane and can speak for quality of gas and or extract used with that gas. I’ve used several gas suppliers before. They have good prices but no diptubes.

Hi 710enigmatic. I’m in the extraction hydrocarbon business. Matheson is not supporting the industry because of the current situation with federal laws. If you are still looking for a source of gas, let me know. Least I can do is let you know if you are buying OK now
