WILMINGTON, Delaware (April 14, 2008) – Thermo Fisher Scientific Inc., the world leader in serving science, today announced the introduction of a Sample Position Illuminator feature for the revolutionary Thermo Scientific NanoDrop™ 8000 Spectrophotometer. The NanoDrop 8000 takes full spectrum UV/VIS absorbance measurements of eight 1 ul samples in 20 seconds, allowing researchers to work with greater numbers of samples in less time while providing the overall capabilities and ease of use of the groundbreaking Thermo Scientific NanoDrop 1000 Spectrophotometer. The new Sample Position Illuminator keeps track of the samples to be measured by lighting up wells from beneath the plate. This helps the user to know which wells to draw from for the next measurement, reducing fatigue and human error. The Sample Position Illuminator is simple to use and is linked to the existing graphical interface in the latest software for the NanoDrop 8000. Prior to measurement, the user selects the samples to be measured from the on screen position indicator. The Sample Position Illuminator then lights up the corresponding wells that are to be measured. The user may also take advantage of three unique features when using the new software and accompanying Sample Position Illuminator: The Auto Column Advance feature increases throughput by automatically lighting up the next column to be measured. The system also allows the user to “cherry pick” single or multiple wells for measurement which are then lit up by the Sample Position Illuminator. The user may define measurement limits, such as upper and lower concentrations of an analyte (e.g. 100ng/ul dsDNA +/- 20 ng/ul). Wells that are determined to be “out of limit” will be identified by both flashing lights under the sample plate and a color code on the plate results summary screen. As of April 2008, the Sample Position Illuminator and accompanying software ship as standard with Thermo Scientific NanoDrop 8000 instruments.
