Do not allow moisture to leak into the instrument interior.
Cleaning the Instrument
Clean the instrument regularly using approved methods (wipe off spilled chemicals
immediately).
1.
Use a lint-free cloth dampened with a weak solution of detergent and water to wipe the
surface as necessary.
2.
Repeat using a cloth dampened with plain water.
3.
Dry the surface with another cloth.
Lamp Replacement
The xenon flash lamps used in Evolution spectrophotometers are extremely long lived. Each is
rated for service equivalent to continuous flashing for a period of three years and is covered
under warranty by us for three years. Under typical operating conditions the lamp will not
require replacement within ten years.
INSIGHT software tracks lamp use and reports remaining lamp life on the Lamp tab in the
System Settings.
Re-alignment of the instrument optics is required following replacement of the lamp. This
means that the process must be completed by a trained and equipped service engineer, either
in the field or at one of our service depots.
Live Readings
In spectrophotometers with traditional, short lived, tungsten or deuterium/tungsten sources
the lamp is always on. It is common for the software running these instruments to display a
value for the absorbance even when the instrument is not actively running an experiment.
The xenon flash lamp is only on when actively making a measurement, so no such display is
present in our software. If you wish to monitor live absorbance readings you can do this using
the Live Display mode in INSIGHT software. Refer to the INSIGHT software user guide or
the Help system within the INSIGHT software for details.
