Dispersion unit Capacity (ml) Suitability Notes
dispersants are either expensive
or hazardous.
Hydro EV 600 - 1000
The flexibility of the Hydro EV
allows you to select dispersant
volumes suitable for certain
applications.
Measured in a standard labor-
atory beaker rather than being
added and drained auto-
matically.
Hydro SV 7
Useful when the sample or dis-
persant is toxic or expensive.
Amount of sample may limit
amount of dispersant that can
be used, or amount of dis-
persant may be limited itself.
Enables the Mastersizer to be
used for particle-in-liquid size
measurements.
Hydro SM 120
Useful when the amount of
sample available limits the
amount of dispersant that can
be used to dilute it, or where just
a small volume of dispersant is
available.
Capacity is dependent on the
length of sample pipe used to
connect to the cell.
Additional accessories: Heater/chiller unit (not shown)
Connection of a heater/chiller circulator unit to the water jacket connections at the front
of the wet cell, enables the temperature of the sample to be altered.
The heater/chiller circulator unit is not compatible with the Hydro SV.
Control of the Hydro dispersion units
The Hydro dispersion units can be controlled using the Mastersizer software in two ways:
l
Automatically — as part of a Standard Operating Procedure (SOP). The software
will guide you through the measurement progresses.
l
Manually — using the software accessory controls. These allow for individual
selection and operation of the dispersion unit's functionality, which is useful in
method development prior to SOP construction.
A fully manual accessory connected to the optical unit will not have an auto-
mated or manual software control but can be controlled directly.
