.
Similarly, make a connection between the outlet (top connection) of the
flow cell
Ã
to the top connection of the Dispersion Unit
Ä
with sample
tubing. Pass the tube through the cover by squeezing the tube and fitting it
into the “keyhole” recess
Å
. Make sure the tube is not constricted.
.
Ensure that all sample tubing is arranged such that there are no twists or
loops. This is because the flow cell and tubing drain under gravity.
.
If your sample and dispersant are safe to be disposed of into the water sys-
tem, connect a length of drain tubing between the drain of the Dispersion
Unit and a sink, otherwise place a suitable sized beaker or conical flask (at
least 150 ml capacity) below the drain outlet. Again, ensure the tubing is ar-
ranged such that the Dispersion Unit can drain under gravity.
.
Attach the 37 way D type connector (digital I/O) from the Controller Unit
to the digital I/O socket on the Mastersizer.
.
Attach the Dispersion Unit cable on the Dispersion Unit to the 15 way D
type connector on the Controller Unit.
.
Connect the mains power cable into the power socket at the rear of the
Controller Unit.
