3.4 Installation diagram
The peristaltic pump and the switching valve of the 872 Extension Modul
Sample Prep can be installed in different ways, depending on the applica-
tion. Illustration 3: Installation diagram – dialysis shows in exemplary
manner how the peristaltic pump of the extension module can be utilized
for pumping the acceptor solution during dialysis.
The arrangement of the modules in the diagram corresponds to the front
view of the extension module. Fluid container, dialysis cell, sample pro-
cessor and IC instrument are not shown in the diagram.
