Beckman Coulter introduced the Gallios Flow Cytometry system. The instrument’s detection capabilities and easy-to-use software, combined with new dyes facilitates superior performance of multi-color flow cytometry assays, according to Beckman Coulter.
A particular emphasis on optical and electronics design, combined with powerful automation and software tools, allows Gallios to enhance the efficiency and analytical capabilities of flow cytometry laboratories. Patented 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 houses up to three highly reliable, solid-state lasers in standard red and blue, with violet available as an option. Interchanged 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 m in diameter, according to the company. 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 of up to 62 parameters can be processed per analysis, at acquisition rates of 25,000 events-per-second, with high yield. Three scaleable configurations allow for the future addition of more lasers and fluorescence detectors as the applications for complex multi-color flow cytometry expand.
