À
Controller unit
The Controller Unit is used to power and control the Dispersion Unit.
Á
Dispersion unit
The dispersion unit is where the sample and the dispersant is mixed and then
pumped to the flow cell of the Mastersizer.
Â
Sample out
The sample out port is the exit point where the sample/dispersant leaves the
Dispersion Unit for the Mastersizer and cell.
Ã
Sample return
The sample return port is the entry point where the sample/dispersant returns to
the Dispersion Unit from the cell in the Mastersizer.
Ä
Drain
The drain is the exit point where sample/dispersant drains from the Dispersion
Unit.
Å
Drain control
The drain control is a lever that opens and closes the drain. The drain is closed
when the lever is fully clockwise (when viewed from the right hand side) and the
drain is opened by moving the lever in an anti-clockwise direction.
Æ
Tank cover
The tank cover stops ingress of dust when the system is left for extended periods
or to prevent evaporation or the release of fumes when the system is in use (e.g.
when using a noxious solvent or sample).
Ç
Pump speed display
Indicates the speed of the pump stirrer in rpm.
È
Speed control
The speed control controls the speed of the stirrer and pump, hence the flow rate
of sample/dispersant through the cell. With the speed control turned fully
