Gallios Flow Cytometer from Beckman Coulter

The Gallios Flow Cytometer is a research system that delivers analytical excellence by coupling extraordinary sensitivity, resolution and dynamic range with high-speed data collection. Along with the unprecedented detection capabilities of the instrument, the Gallios includes easy-to-use software and automation to facilitate superior performance of multi-color flow cytometry assays.

Designed to fit your needs, today and tomorrow, the Gallios flow cytometer provides efficient acquisition of excellent quality data from up to 10 colors with advanced optical design for enhanced sensitivity for multicolor assays. With customized forward scatter, to achieve the most accurate size measurement, and optimized electronics for high resolution and fast, accurate processing, the Gallios was designed for your research needs.

Gallios is optimized for unparalleled signal to noise resolution in all parameters and its quick and easy setup of automated walk-away processing improves your workflow while its remote diagnostics minimize downtime and allow you to maximize lab productivity.

Developed for the research and biopharmaceutical markets, with a particular emphasis on optical and electronics design, combined with powerful automation and software tools, The Gallios enhances the efficiency and analytical capabilities of flow cytometry laboratories. Electronics provide accurate and efficient digital signal processing at high event rates over a wide dynamic range of fluorescence intensities. These benefits are packaged in a compact analyzer that delivers stable performance over long periods of time and across a wide range of operating temperatures.


The Gallios offers up to four highly reliable, solid-state lasers in standard red and blue, with violet and yellow lasers available as an option. By incorporating the optional 405nm violet laser and an optional 561nm yellow laser, the Gallios Flow Cytometer offers a greater choice of fluorochromes to perform sophisticated multicolor experiments.  With the new 561nm laser system you can analyze multiple fluorescent proteins simultaneously, as well as benefit from a greater ability to detect red fluorescent proteins. Easily interchangable optical filters facilitate detection of a variety of dyes and wavelengths.

An innovative forward-scatter detector provides up to three measurements of cell size and visualization of particles down to 0.404 µm in diameter. A side-scatter detector incorporates an independently focused, high-performance photodiode with electronic attenuation. Six fluorescence detectors provide simultaneous acquisition of up to six fluorescence signals. Up to four fluorescence detectors can be added to the system, enabling concurrent reading of up to 10 colors. Simultaneous measurements of integral, peak and width are available for all parameters, including scatter and fluorescence signals. A selection from up to 62 parameters can be processed per analysis, at acquisition rates of 25,000 events-per-second, with high yield. Four scalable configurations allow for the future addition of more lasers and fluorescence detectors as the applications for complex multi-color flow cytometry expand.
