Position Illuminator

When measuring samples in a 96-well format on the Thermo Scientific
NanoDrop 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 adefined range (e.g. 100ng/ul ±20ng/ul).
