The complete cell is inserted into the cell bay of the optical unit. With the cell in position,
a motor within the cell rotates the stirrer bar that continually circulates the dispersant
around the cuvette to make sure it is adequately dispersed prior to a measurement. The
stirrer speed is controlled using the Mastersizer software or front panel dial. Refer to the
Mastersizer 3000 User Manual for advice on sample addition.
Once measured with the Mastersizer optical unit, the sample can be disposed off. First
remove the SV cell, then remove the cuvette and dispose of the sample appropriately.
Note: As the Hydro SV incorporates a magnetic stirrer for the dispersion of the
sample, it is recommended that the Mastersizer 3000 is not used anywhere
near external magnetic fields, or used where stationary magnets may impact.
These may affect the effectiveness of the stirrer bar sample dispersion.
Recommended sample criteria
l Size typically less than 200 µm
(sample and dispersant dependent)
l Non-magnetic samples only
l Non-abrasive samples
