16. Maintenance and Warranty
Cleaning
The primary maintenance requirement of the NanoDrop
®
ND-1000 Spectrophotometer is keeping the measurement pedestal surfaces
clean. Upon completion of each sample measurement, wipe the sample from the upper and lower pedestals to prevent sample
carryover and avoid residue buildup. It is also recommended that both measurement pedestals be cleaned with de-ionized water upon
completion of a testing series.
Calibration
Wavelength
The wavelength is auto-calibrated based on known peaks in the xenon lamp spectra each time the software is started. No calibration is
required by the user.
Pathlength (Accuracy)
Generally, this is not required as field experience has shown that the path does not change appreciably even after several years of
heavy use. However, it is good practice to check the calibration every six months using CF-1 calibration fluid. A calibration check
procedure is available from the Downloads section on the Support tab at

.
Parts That Require Replacement
In general, the only part that should periodically require replacement is the flash lamp. The flash lamp should last a minimum of 30K
measurements. There is no way to test the flash lamp to confirm its remaining life. When the flash lamp fails, the light output will
become very erratic or stop altogether.
Warranty
All spectrophotometers and accessories manufactured by NanoDrop Technologies are warranted against manufacturing defects in
parts and labor for a period of one year. Preventive Maintenance as well as additional one, two, and three year warranty extensions are
available. Plan descriptions can be found at the following link:
