The plate positioner provides stable, repeatable positioning for microtiter well plates. This allows faster data throughput and easier analysis of the resulting data. The plate positioner is autoclave safe and intended for use with preclinical in vivo imaging systems like the IVIS® system. The IVIS® portfolio of instruments is the industry’s most the versatile and advanced pre-clinical in vivo imaging technology available. The IVIS® platform can address the widest range of applications with the highest level of sensitivity for bioluminescence, fluorescence, high-throughput 2D or tomographic imaging. IVIS® has lead the industry in multimodal innovation, integrating functional and anatomical technologies within a single instrument or through cross-platform enablement.
