Fig. 1From: Effects of metal corrosion in the pump of a dialysis machine on the sterility of the terminal dialysate by spike-and-recovery testing with bacteriaExperimental circuit. To verify the bacterial contamination level of the pump and the terminal dialysate, an ETRF was installed ahead of the pump to avoid contamination from the environment. Dialysate was introduced into the circuit at a flow rate of 700 mL/min, and the terminal dialysate samples were collected from the sample port distal to the pumpBack to article page
