Cytation™ 7

Cytation™ 7 Cell Imaging Multi-Mode Reader combines automated digital upright and inverted widefield microscopy with conventional multi-mode microplate reading in a unique, patented design. The inverted microscopy module provides sample visualization from 1.25x to 60x magnification in fluorescence, brightfield and color brightfield for a broad range of applications. The upright microscopy module with reflected light imaging enables even more applications such as ELISpot or fast slide scanning and ROI detection workflow. Cytation 7 includes continually variable bandpass monochromators for versatility and performance for general multi-mode plate reader applications. Temperature control to 45 °C, optional Peltier Cooling Module, gas control and shaking expand the applications for kinetic cell based assays. Cytation 7 is controlled by Gen5™software, which combines ease-of-use with powerful processing and analysis capabilities.
