BMG POLARstar Galaxy Multifunctional Fluorescence, TRF, FI, FRET, Polarization and Absorbance
Equipped with UV-VIS Fluorescence and Absorbance
 for top- and bottom- read assays

easurement principles for the wide range of applications

The POLARstar is a fully automated microplate based multi-detection reader which incorporates numerous different measurement principles:
  • Fluorescence (UV and VIS range)
  • Time Resolved Fluorescence TRF
  • Fluorescence Intensity top to bottom capabilities FI
  • Fluorescence Resonanace Energy Transfer FRET
  • Polarization FP
  • User choice of Fluorescence filters included
  • Absorbance reading mode (UV and VIS range)
  • User choice of Absorbance filter included
  • Temperature control and microplate-shaking included
  • Adjustable bandwidth range
  • 6-384-well plate capability

By integrating a high intensity xenon flash lamp and liquid light guide technology, the BMG models can cover the wavelength range from 240 to 740 nm in  96 well plate formats. Measurement Modes:  Wavelength: Range 250nm to 740nm wavelength range, with the option to  include up to 8 Excitation and 4 emission wavelengths with initial choice of 2 filter pairs. Measurement Time: 16 seconds for full 96 well plate reading.
Other Features can be included: Top-to-bottom reading, programmable shaking, 25 to 45 °C incubation and Polarization



Temperature-regulated heating provide uniform incubation from 25 to 45°C.

Endpoint, slow and fast kinetic measurements

Kinetic applications with up to 250 kinetic points can be defined, with interval times from 100 ms to several hours. In addition, there is the possibility to measure where it is important in a kinetic study.

Multi-color detection

The fast filter wheels and the ability to define up to 8 sets of filters, each with individual gain and measurement timing parameters, allow analysis of multiple fluorophores in a single well (TRF, FRET, dual-emission, DNA-detection).
