(More manufacturers/versions generally available)
Lots of labs also use Model A (alkaline electrolytic techniques) and Brand B, nevertheless with commonly reduced purity or greater cost relative to Hovogen and Peak Scientific

seven–10. Other Noteworthy Units
Labs may additionally use hydrogen cylinder setups with purification filters, although some great benefits of generators—like protection, continuity, and purity—typically outweigh conventional cylinders
