Title: Dialysis sampling - uses a sterile container with coupling tube to take sample and be used again after cleaning and sterilising
IPC: G01N1/20
Filed: 1992-02-04
Abstract: To take a standard sample of dialysis water and concentrate, a standard and reproducable sample is taken from an unaccessible section of the supply line.
