FluorChem R

Satisfy everyone in your lab with an imager that does it all—and takes the complication out of getting reliable, fully analyzed data too! Meet the FluorChem™ R system.


See those tiny, hard to detect bands on a 10.4 inch screen with a whopping 8.3 megapixel CCD camera.

Easy To Use

Who says you have to be in the lab to image your Westerns? Control the system and access your data from just about anywhere using browser-based Digital Darkroom software.

Built-in IR and RGB light sources gets you crisp, clear images every time—regardless of your application.

How Can FluorChem R Help You?

I'm tired of doing multiple exposures with film to get the images I need

With a 5-log dynamic range enabled by the large, high-resolution CCD sensor in FluorChem imagers, you can detect faint bands and bright bands without oversaturating in a single exposure. And you get your data in minutes, with no waste at all.

My proteins are close in molecular weight, and I need to be able to differentiate between them on a single blot

The 8.3 megapixel CCD cameras in FluorChem imagers ensure that you'll get the best image quality and the resolution you need to do accurate analysis, and differentiate between bands that are close together. The FluorChem M and R also enable multiplex fluorescent imaging, letting you analyze overlapping proteins in the same blot.

I don't want anything complicated—I just want to see my proteins

Digital Darkroom software makes taking images super simple. Simply load the blot or gel, select a pre-programmed protocol on the touch-screen interface, and hit "Expose." The software automatically calculates and sets exposure and camera settings in order to acquire the best image. Once you have your image, analysis can be done on the spot in a matter of minutes. Digital Darkroom can even be accessed and controlled remotely, so you can review images and do analysis from your desk or even your phone.

We're doing a lot of different applications, and we don't want to have to buy multiple imagers

FluorChem imagers are versatile—the FluorChem R has true multi-mode capabilities, with UV fluorescence, white light, chemiluminescence, visible fluorescence, and infrared fluorescence imaging, all in one compact system. Cover all your application bases with one easy-to-use system. The FluorChem E and M can be upgraded to the R for ultimate flexibility.
