BMG Polarstar Galaxy with Fluorescence,
FI, TRF and Absorbance

Polarstar

Four measurement principles for the widest range of applications

The Polarstar is a fully automated microplate based multi-detection reader which incorporates four different measurement principles:

               • Fluorescence 
               • Fluorescence Intensity
               • Time-Resolved Fluorescence
               • Absorbance

It is designed for the widest possible range of non-radioactive labeled applications:

• Ca2+ Measurements (e.g. Ca2+ Flux with Fura-2 or Indo-1)
• Enzyme Activity
• Cell Toxicity, Proliferation and Viability
• ATP Quantification
• Immunoassays


By integrating a high intensity xenon flash lamp and liquid light guide technology, the Galaxy can cover the wavelength range from 250 to 740 nm. The Galaxy can read plate formats of 96-well plates in all 4 measurement modes. Top to bottom readings.
 

 
 

Incubation

Temperature-regulated heating plates above and below the entire plate movement area provide uniform incubation up to 45°C.

Endpoint, slow and fast kinetic measurements

Kinetic applications 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 filter, each with individual gain and measurement timing parameters, allow analysis of multiple fluorophores in a single well (FRET, dual-emission, DNA-detection).
