​The ChemiDoc XRS+ system offers fast and sensitive chemiluminescence detection in addition to gel and blot documentation of fluorescent and colorimetric samples. The system includes a supersensitive 16-bit CCD camera that is supercooled for detection of faint samples.

The ChemiDoc XRS+ system can be used for imaging with a wide variety of applications that require high resolution and sensitivity (such as chemiluminescent western blots).The ChemiDoc XRS+ system eliminates the need to use costly and unreliable X-ray film technologies while providing quantitative and reproducable data in seconds.
The system features a signal accumulation mode (SAM), which guides a user through determining optimum exposure time and capturing a desired image of a chemiluminescent sample​
