The type of SF6 you need depends on your application, such as calibration, industrial insulation, or medical use.

: Best for calibration gas . They offer various concentrations (e.g., 1000 PPM, 1300 PPM, 150 PPM) in 17-liter disposable cylinders.

: Offers Portagas calibration mixtures, such as 1000 ppm SF6 in 100-liter aluminum cylinders.

: Specializes in medical-grade SF6 (Intraocular Gas) for surgical applications, typically sold in 125g to 450g tanks.

: Sells high-purity (99.999% research grade) SF6 in larger 18-lb and 35-lb low-pressure steel cylinders. Gas Applications - Sulphur Hexafluoride
