(Extra models/products normally offered)
Several labs also use Brand A (alkaline electrolytic units) and Model B, even though with usually lower purity or bigger Charge relative to Hovogen and Peak Scientific

7–ten. Other Noteworthy Programs
Labs can also make use of hydrogen cylinder setups with purification filters, nevertheless the benefits of turbines—like basic safety, continuity, and purity—frequently outweigh common cylinders
