Note: The Hydro SV dispersion unit will generally be referred to as the "Hydro
SV" or "SV cell" or just "cell".
Cell shroud assembly
The cell shroud prevents the emission of laser radiation. It also prevents stray light affect-
ing a measurement and reduces noise emissions.
The cell shroud incorporates a mechanical shutter arm that opens when inserted into the
optical unit. With the shutter open laser light is allowed into the sample area. When the
SV cell is withdrawn, the shutter moves back into position to prevent the emission of laser
light.
!
Warning!
The system must never be used if the cell shroud or shutter arm is damaged.
Cell handle and unlock button
!
Warning!
Never attempt to lift the optical unit by the cell handle. Read the Health and
Safety section of the Mastersizer 3000 Basic Guide for details of correct moving
techniques.
To ensure optimal location prior to measurements being performed, a lock motor secures
the cell into a defined position when the cell is inserted into the sample area.
To remove the cell:
1. Press the unlock button on the cell handle.
2. This releases the lock motor and raises the cell slightly, ready to be withdrawn
from the optical unit.
