Microcapillary Guava easyCyte8HT system is very simple to operate and an alternative technology in flow cytometry. It is equipped with solid state 488nm and 640nm lasers, allowing simultaneous detection for up to 6 fluorescent parameters. The cytometer utilizes small sample volumes and requires no sheath fluid to minimize waste. The cytometer possesses a robotic sample tray that automatically handles a 96-well plate. The powerful InCyte software has a drop & drag menu, HeatMap for data presentation. It enables semi- automated compensation with ability to post-acquisition compensation and automated calculation of IC50/EC50 curves.
