Best practices for cuvette measurements
To measure a sample using a cuvette
• The instrument arm can be up or
down for cuvette measurements.
• Use 10 mm, 5 mm, 2 mm or 1 mm
cuvettes up to 48 mm tall.
• Clean and dry cuvette after each
measurement.
• Use cuvettes that are free of scratches
and avoid fingerprints which may
affect results.
• Use quartz cuvettes or UV-grade
plastic cuvettes to measure samples
with analysis wavelengths in the
UV range (<340 nm).
• Micro, semi-micro, and ultra-micro
cuvettes should be masked.
• Fill cuvettes with enough blanking or
sample solution to cover instrument
optical path (2 mm sample beam is
8.5 mm above cuvette bottom).
• Lift instrument arm and make sure
cuvette holder is free of debris.
• When inserting quartz or masked
plastic cuvettes, align cuvette light path
with instrument light path.

NOTICE
• To prevent damage from spills, keep containers of liquids away from the instrument.
• Do not use a squirt or spray bottle on or near the instrument as liquids will flow into
the instrument and may cause permanent damage.
