For details on how to fill the cuvette with dispersant and then sample, refer to Filling the
cuvette on the facing page.
The sample cuvette can be removed to allow cleaning; the cuvette locks are rotated and
the complete cuvette can be removed. The cuvette windows are delicate and should be
treated with caution; refer to Hydro SV procedures on page97 for details on removing
the cuvette and cleaning the cuvette windows.
The cuvette has a maximum capacity of 7 ml in total:
Max. (7ml)
Min. (6ml)
l This corresponds to a minimum volume of 6 ml dispersant + 1 ml maximum of
sample. If more than 7 ml of sample/ dispersant is inserted the cuvette will over-
flow.
l
The maximum volume when filled to the bottom of the window chamfer is 7 ml.
l
The minimum volume when filled to the marks on the metal work as shown in
the illustration is 6 ml. This is the amount of dispersant that the cuvette must be
filled with to make sure the background measurements are suitable.
