It is also possible to use cuvettes with 5 mm, 2 mm, 1 mm or 0.5 mm path lengths, but
there may be an adapter necessary. Please ask your cuvette supplier for a suitable
adapter.
The minimum volume for accurate measurements depends on the cuvette type used; it
is necessary that the light passes through the sample for accurate measurements.
Center height is 8.5 mm.
Note: The cuvette holder is not removable. Do not pour any cleaning solution into the
cuvette holder as larger amounts of liquids can get into the instrument and cause damage.
