CentroPRO is the newest member of the microplate family of BERTHOLD TECHNOLOGIES. The instrument is universally applicable for research and routine. It enables the measurement of all important glow-type luminescence applications, e.g. reporter genes, ATP determination or cell viability.  
  
Instrument Concept  
  
Detector sensitivity and stability are the result of BERTHOLD TECHNOLOGIES experience with thousands of photon counters. True photon counting has the benefit that no user parameters need to be set, ensuring the same conditions are used for every measurement during the instruments life time. The fast photon counting circuitry provides a dynamic range in excess of six orders of magnitude, which complements the concentration range of the latest assays.  
  
A patented design of the optical system achieves absolute minimization of cross-talk (down to 10-6 depending on the type of microplate).  
  
Solid 96 well plates, as well 8 well and 12 well strip plates can be measured. Inside the instrument precise x and y drivers ensure exact positioning of the wells with respect to the detector.
