What is it indicated for?
The device is intended to be used as components of a hemodialysis water purification system to remove organic and inorganic substances from water used to dilute dialysis concentrate to form dialysate, and to produce purified water for other purposes such as dialyzer reprocessing and equipment rinse and disinfection. Upon exhaustion, these tanks will be replaced with other Deionization Tanks containing newly regenerated resin or with new resin altogether, or in the case of Carbon Tanks, with tanks containing fresh virgin carbon.
Indications for use as stated in the FDA summary.
