SPECTROstar Nano Absorbance Plate Reader with Cuvette Port

The SPECTROstar Nano, equipped with BMG LABTECH’s ultra-fast UV/vis spectrometer, can measure absorbance over the entire spectrum (220 nm–1000 nm) in less than one second per well. Many common assay protocols are predefined, just a mouse click away, making it an ideal instrument to capture all the absorbance assays in a microplate or cuvette.


  • High-speed absorbance measurements
  • Measurements in up to 1536-well plates
  • Integrated cuvette port
  • LVis Plate compatibility
  • Incubation up to 45 °C
  • Multiple shaking options
  • Well scanning at up to 900 data points per well
