Bio-Rad ChemiDoc XRS+

This used Bio-Rad ChemiDoc XRS+ is a gel and blot imaging system designed to capture high quality images of chemiluminescent, colorimetric, and fluorescent samples for molecular biology and protein research. The system pairs a cooled CCD camera with a UV transilluminator and white light conversion screen to support a wide array of staining methods, including ethidium bromide gels, Coomassie stained protein gels, and chemiluminescent Western blot detection. Its enclosed dark chamber and motorized lens allow for consistent, reproducible image capture across a broad dynamic range. Laboratories use the ChemiDoc XRS+ together with Image Lab software to acquire, process, and quantify band intensities from gels and blots, which supports protein expression studies, nucleic acid quantification, and general electrophoresis documentation. The system has been a workhorse in academic, pharmaceutical, and biotech labs for producing publication quality images and generating quantitative data used in downstream analysis. Offered here in used condition, this unit continues to provide dependable imaging performance for laboratories that need a proven documentation system without investing in new equipment. It is a solid fit for research groups, teaching labs, and quality control departments running routine gel and blot analysis.
