40 Cary 100/300/4000/5000/6000i/7000 Spectrophotometers User’s Guide
Cleaning
Any spills in the sample compartment should be immediately wiped
up and any deposits on the sample compartment windows should
also be removed.
The exterior surfaces of the Cary spectrophotometer should be kept
clean. All cleaning should be done with a soft cloth. If necessary, this
cloth can be dampened with water or a mild detergent. Do not use
organic solvents or abrasive cleaning agents.
Source lamps
Instructions for how to change and align both the visible and
ultraviolet (UV) lamps for Cary instruments are included in the Help
provided with the software.
For both lamps the following safety precautions should be observed:
WARNING
Hot Surface and Electrical Shock Hazards
Lamp surfaces and mounting brackets will become hot during operation and
will remain hot for some time after being switched off. The temperatures are
sufficient to cause burns.
The UV and mercury lamps operate at high voltage. Contact with this voltage
can cause death, serious injury, or painful electric shock. Before changing
the deuterium or visible lamps, ALWAYS switch off the instrument, remove
the power supply cable and allow the lamps to cool.
CAUTION
Care must also be taken when removing lamps. Touching the glass envelope of
either the deuterium or visible lamp will reduce its efficiency. NEVER touch the
glass surfaces of new lamps. ALWAYS handle a lamp by its base, using a soft
cloth.
