NanoDrop® ND-1000 Spectrophotometer

The NanoDrop® ND-1000 is a full-spectrum (220-750nm) spectrophotometer that measures 1ul samples with high accuracy and reproducibility. 

A 1ul sample is pipetted onto the end of a a fiber optic cable (the receiving fiber).  A second fiber optic cable (the source fiber) is then brought into contact with the liquid sample causing the liquid to bridge the gap between the fiber optic ends.  The gap is controlled to a 1mm path.  A pulsed xenon flash lamp provides the light source and a spectrometer utilizing a linear CCD array is used to analyze the light after passing through the sample.

The small sample requirement of 1ul makes the NanoDrop ideally suited for measuring:

  • Nucleic acid concentration and quality of nucleic acid samples up to 3700 ng/ul (dsDNA) without dilution
  • Fluorescent dye labeling density of nucleic acid microarray samples
  • Protein analysis (A280) up to 100 mg/ml (BSA)
  • Bradford Assay analysis of protein
  • Cell density measurements
  • General UV-Vis spectrophotometry

Access to the NanoDrop® is free of charge to GEC facility users.
