SULFUR HEXAFLUORIDE (SF6)
An inert, odorless, colorless, non-toxic gas, sulfur hexafluoride is used as both the active ingredient in ultrasound contrast agents and as a
retinal tamponade. Manufactured in production lots under cGMP conditions, sulfur hexafluoride is available to fill your gas or pharmaceutical chemical
requirement. Custom specifications or packaging can be developed as required.
