Flow Cytometer

A flow cytometer is used to analyze the physical and chemical characteristics of particles in a fluid as it passes through at least one laser. Cell components are fluorescently labelled and then excited by the laser to emit light at varying wavelengths. Marshall Scientific Specializes in refurbishing flow cytometer machines to run at peak performance, and to produce descriptive and accurate flow cytometry data analysis reports. We specialize in refurbishing Becton Dickenson Biosciences FACSCAlibur Flow Cytometer Systems and can guarantee they will operate at factory specifications. Please take a look at some of our flow cytometer systems we have in stock and feel free to give us a call or send us an email if you have any questions.
