NanoDrop Eight UV-Vis Spectrophotometer |
Thermo Scientific NanoDrop Eight UV-Vis Spectrophotometers are used in academic, biopharmaceutical, core and bioproduction facilities, to measure between 1 and 8 microvolume nucleic acid and protein samples simultaneously. Increase the chances of success in your analyses with efficient analysis of your sample quantity and quality using the Thermo Scientific™ NanoDrop™ Eight UV-Vis spectrophotometer. Ideal for larger number of nucleic acid and protein samples. NanoDrop Eight measures 8 samples at a time in less than 20 seconds. Software identifies sample contaminants and reports true sample concentration with the built-in Thermo Scientific™ Acclaro™ Sample Intelligence technology. Optional software allows you to more easily comply with 21 CFR Part 11 regulation.

- User-friendly software that includes custom methods and data export capabilities
Position Illuminator
When measuring samples in a 96-well format on the Thermo ScientificNanoDrop 8000 Spectrophotometer, an eight-channel pipettor is used to draw 1 ul samples from a microtiter plate which are then dispensed onto the eight optical measurement surfaces.
The Sample Position Illuminator keeps track of the samples to be measured by lighting up wells from beneath the plate. This helps the user readily identify which wells to draw from for the next measurement, thus reducing fatigue and human error.
The sample position illuminator is simple to use. Prior to measurement, the user selects the samples to be measured from the on screen position indicator (selected wells are in green).
The sample position illuminator then lights up the corresponding wells of the plate that are to be measured:
The user then simply draws from the illuminated wells.
Additional Features:
- Auto advance: This increases measurement throughput by automatically
- lighting up the next column to be measured.
- "Cherry picking": User can select any single or multiple wells which are
- then lit up by the sample position illuminator.
- Measurement limits: The user can define upper and lower concentration
- (or absorbance) limits such that a well will begin to flash if the
- measurement falls out of a defined range (e.g. 100ng/ul ±20ng/ul).
