5. Take the cuvette and place into the SV cell. Secure with the cuvette locks.
6. The stirrer bar will attach to the stirrer motor.
7. Press the speed dial to turn the Hydro SV on and test the SV operates correctly; the
stirrer bar should spin.
8. Insert the SV cell into the optical bench. The instrument will again align, and the
obscuration should then be checked.
9. If the obscuration is acceptable, continue with the measurement; if the obscur-
ation is not acceptable, repeat the sample insertion.
Advanced measurement cuvette filling.
The cuvette has a maximum capacity of 7 ml in total. This corresponds to a minimum
volume of 6 ml dispersant + 1 ml maximum of sample.
If more than 7 ml of sample and dispersant is inserted, the cuvette will overflow.
Therefore should the amount of sample and dispersant required to reach the desired
obscuration exceed 1 ml, which would overflow the cuvette, follow these actions:
