￭ Shorten the tubing to a suitable length and connect it to the rins-
ing pump of the second 843 Pump Station.
3.9 Installing and connecting the pump
The installation of the 843 Pump Station is described in its manual.
Use the black 6.1826.160 pump tubing made of Viton ® (trade name of
the DuPont Co.) that is supplied along with the 864 Robotic Balance Sam-
ple Processor. It has excellent resistance against hydrocarbons. A different
tubing material is to be used when other solvents are used. Clarify in such
cases the resistance of the material against the solvent being used.
