Fluorescence based flow cytometry
Fluorescence Based Flow Cytometry

  • Invented in 1968 in the University of Münster, Germany at the Institute of Radiobiology by Professor Dr.Wolfgang Göhde.

  • First Published paper in Jan. 1969 “Dittrich W., Göhde W. "Impulsfluorometrie bei Einzelzellen in Suspensionen", Zeitschrift für Naturforschung (1969), Tübingen, Band 24 b, Vol. 3”

  • “Impulse Fluorometry” was the name used in the paper, “Impulse Cyto Photometry Technology” was called and still can be found in the Internet.

  • Hertzenberg started flow cytometry together with Bernhard Shaw (at that time V. P. of Becton Dickenson) in 1973, when the NIH had decided to develop an own American Flow Cytometer

More than 30 years of experience
More than 30 years of experience...


The ICP 11.

The first commercial flow Cytometer is born -the legendary ICP-11, developed in Münster and distributed by

Phywe AG, Göttingen.

Electronics size and fashion changed since that time...
