From cell connection
The ‘from cell' connections on the dispersion unit and wet cell have blue identifier mark-
ings.
The top connection on the dispersion unit connects to the sample 'in' pipe. This is where
the sample returns in to the dispersion unit from the top ‘from cell' connection of the wet
cell (blue collar) in the optical unit.
Connection of the wet cell sample pipes
To connect the wet cell pipes:
1. Push the wet cell pipe onto the connection.
2. Make sure it is pushed on as fully as possible to prevent any risk of leaks.
3. Follow the Hydro MV/LV wet cell connection procedure for connection to the wet
cell.
Removal is the reverse of the procedure. Make sure the cell is empty before removal.
Suitable aqueous and non-aqueous wet cell pipes are available direct from Malvern Instru-
ments.
Dispersion unit controller
The Dispersion unit controller is used to power and control the dispersion unit.
