Lower internally regulated dispersant inlet port - for
aqueous dispersants
!
Caution!
This port is not chemically compatible due to the presence of an internal pres-
sure regulator.
The lower dispersant inlet port will be connected to a clean source of dispersant. For most
sample applications the dispersant will be water (aqueous). An internal pressure regulator
controls the dispersant input flow.
In the software the lower dispersant inlet port is referred to as Automatic Fill (Internal).
The valve will be in a closed state when in standby or when power is supplied to the
accessory.
Note: Refer to the Mastersizer 3000 Basic Guide for the site requirements of
the dispersant input.
Connection of the lower/aqueous dispersant pipes
1. Press the lock down on the connection to open.
2. Insert the aqueous dispersant pipe into the connection until the lock is engaged.
3. Pull the dispersant pipe gently to make sure it is secure.
To remove, press the lock down on the connection and pull pipe to remove.
Suitable aqueous pipes are available from Malvern Instruments.
Note: Using the Accessory controls in the SOP, the inlet ports can be used to
both fill and clean the tank. Refer to Control of a dispersion unit via an SOP on
page70.
