17. 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.
Apply 5 ul of dH
2
0 solution onto each bottom pedestal.
Lower the upper pedestal arm to form a liquid column; let it sit for approximately 2-3 minutes.
Wipe away the water form each upper and lower pedestal with a clean lab wipe.
Note: Typically dH
2
0 is sufficient for removal of samples that have dried on the optical pedestals. There are a few cases
(i.e. dried proteins) that may require a more rigorous cleaning protocol. For these cases, we recommend that 0.5M HCl be
substituted for with 5 ul of dH
2
0 to remove any residual HCl. Please follow an HCl application with a water rinse to ensure
any residual HCl is removed. Note: Do not use a squirt bottle to apply de-ionized water or HCl.
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 verify the calibration every six months using CF-1 calibration fluid.
The calibration check procedure is found within the Utilities and Diagnostics module.
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:
