Section 6- Warranty and Maintenance
Solvent Compatibility
The NanoDrop 2000/2000c Spectrophotometer pedestals are compatible with most solvents typically used in life
science laboratories. These include: methanol, ethanol, n-propanol, isopropanol, butanol, acetone, ether,
chloroform, carbon tetrachloride, DMSO, DMF, Acetonitrile, THF, toluene, hexane, benzene, sodium hydroxide,
sodium hypochlorite (bleach), dilute HCl, dilute HNO
3
, dilute acetic acid.
All forms of Hydrofluoric Acid (HF) are incompatible, as the fluoride ion will dissolve the quartz fiber optic cable.
Do not allow alcohol, bleach, acetone or other solvents to remain on the diaphragm surrounding the pedestal for
more than a minute as the adhesive keeping the seal in place may be adversely affected. If the seal comes loose,
please contact
Technical Support. Contact your local distributor for service and Technical Support outside of the US
or Canada.
Decontamination of Measurement Pedestals
If decontamination is necessary, a sanitizing solution, such as a 0.5% solution of sodium hypochlorite (1:10 dilution
of common commercial bleach solutions, freshly prepared), may be used to ensure that no biologically active
material is present on the measurement pedestals.
Note: Do not use a squirt or spray bottle to apply the diluted bleach. Always dampen a laboratory wipe with the
bleach to clean the top and bottom pedestal surfaces as well as the outside of the instrument. Remove
the bleach solution with a lab wipe dampened with water.
Maintenance of the Cuvette System
The cuvette holder assembly block may be cleaned of excess dust using canned air. If any liquid gets into the block,
it is best to use a lab wipe or a lab cotton swab to absorb the liquid.
Note: Do not squirt any cleaning solution into the cuvette holder as the liquid may drip into the instrument.
Follow the recommendations of each specific cuvette manufacturer for the cleaning and maintenance of cuvettes.
Cuvettes with scratches in the optical path should not be used. Ensure all optical surfaces are free of lint and
fingerprints prior to insertion in the NanoDrop 2000c cuvette holder.
