It's a Universal Bicarbonate Cartidge (6) which is designed to be used either with Gambro or Resenius Dialysis Machines and easy adapted to be used with any dialysis machines. This cartridge is used during bicarbonate dialysis to get fresh bicarbonate solution. It's a Cartridge (6), not a bag for that reason it can sustain excess pressure and can not blow up as existing Fresenius bag in case there is an excess pressure.
