RS-G4 Confocal Microscope - Good Condition 2017

Caliber RS-G4: a next-generation confocal solution for accelerated scientific imaging

The RS-G4 from Caliber represents a true revolution in confocal imaging. Designed specifically to meet the demanding needs of researchers, this system offers unrivalled image acquisition speed while ensuring exceptional quality. Thanks to its high-frequency resonant scanner combined with a precision motorised stage, it allows more samples to be captured in less time, optimising overall laboratory performance.

The RS-G4's compact scan head can rotate 360 degrees, offering great flexibility in sample positioning, which is particularly useful for large tissues and embryonic specimens. The head is compatible with both fixed and mobile stages, enabling both in vivo imaging on small animals and ex vivo imaging. The system provides confocal resolution at the cellular level in fluorescence and  reflectance modes .

The image quality delivered by the RS-G4 is the result of high-level software and hardware engineering. Thanks to Caliber's exclusive mosaicking algorithm , the images obtained are perfectly aligned, with no discontinuity between fields. This allows rapid reconstruction of large areas of interest with optimal sharpness. The entire process is controlled by a powerful Windows®-based software suite, integrating features such as multi-channel capture, Z-series, multi-point acquisition and full microscope control.

The versatile RS-G4 has applications in many scientific fields. In neuroscience, it enables rapid scanning of large fixed brain sections. In developmental biology, it provides clear visualisation of animal development from the single-cell stage to the juvenile adult. In pathology, it facilitates the study of ex vivo tissues with confocal details in fluorescence and reflectance. In translational research, it enables precise analysis of microscopic cell activity down to macroscopic structures.

The RS-G4 combines fast acquisition performance, flexibility of use and precision of analysis in a complete system dedicated to advanced scientific imaging. With the RS-G4, Caliber sets a new standard in confocal microscopy for biomedical research.
