Bio-Rad Versadoc 4000

This used Bio-Rad VersaDoc 4000 imaging system is a sensitive CCD based imager designed for chemiluminescent, fluorescent, and colorimetric detection of gels and blots. The instrument features a cooled camera and adjustable lens system that supports high sensitivity imaging for low abundance targets, making it useful for demanding Western blot and multiplex fluorescence applications. Its enclosed chamber and multiple illumination options give researchers flexibility across a variety of staining and labeling chemistries. Laboratories running proteomics and genomics workflows have used the VersaDoc 4000 with Quantity One software to capture and quantify signal intensities from protein and nucleic acid samples, supporting both qualitative documentation and quantitative analysis. Its imaging sensitivity made it a preferred choice for applications requiring detection of faint bands or low concentration targets. This pre-owned VersaDoc 4000 remains a capable imaging platform for labs that need dependable sensitivity without the cost of newer systems. It is well suited for research laboratories and core facilities running routine blot and gel imaging where detection of low signal targets is important.
