Operating Precautions
NanoDrop One spectrophotometers are designed to operate indoors in an environment that
meets our specifications. For details, see the site preparation guide for your instrument.
CAUTION Do not remove the instrument cover. Removing the cover exposes the operator
to sharp edges and delicate fiber optic cables. The instrument warranty is void if the cover
has been removed.
Follow these precautions to avoid damaging your NanoDrop
spectrophotometer during use:
• Use a grounded power cord appropriate for your electrical
service. If the supplied power cord is incompatible or if it
becomes damaged, contact us.
• Do not remove the instrument cover.
• The plate below the arm assembly is made of heat tempered
glass. The LCD display uses heat treated, chemical
tempered glass. Both are rugged and difficult to break.
However, should either the plate or display become cracked
or broken, contact us for replacement.
• Use solvents that are compatible with the instrument (see
Hazardous Materials)
• Do not use hydrofluoric acid (HF) on the pedestals.
Fluoride ions will permanently damage the quartz fiber
optic cables.
• 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.
• Do not attempt to remove the diaphragm around the lower
pedestal as it is permanently affixed to the instrument.
• Do not allow HCl, alcohol, bleach, acetone or any other
solvent to remain on the diaphragm for more than one
minute or it may loosen the seals. If the diaphragm
becomes loose, contact us.
