The drain beaker may hold hazardous samples and dispersants. The drain beaker
holder secures the drain beaker to prevent it from being accidentally knocked over
when the cell unit is removed from the optical bench.
We recommend that the beaker holder is always used.
The cell unit holder is a "parking" area for the cell when it is not in use. This is par-
ticularly useful when more than one dispersion unit is in use. It allows the cell to be
removed and stored without the need to disconnect it from the dispersion unit.
When the cell is "parked" for a short period make sure that the cell is full of disper-
sant. If it is to be parked for longer periods, the unit should be drained and the cell
windows dried. The Essentials manual describes these procedures.
The well lid is used to reduce the escape of hazardous fumes when measuring
using hazardous samples and dispersants. It also reduces the risk of accidental
splashing from the well.
Always use the well lid when making measurements or moving the cell unit.
Always lock the lid into place with the lid locking lever
The lid locking lever is used to lock the well lid in place when measurements are
taking place.

Warning!
If using hazardous dispersants or samples, do not allow the beaker to
become over-full. If dispersants or samples are noxious, the instrument
should ideally be used in a fume cupboard.
