Documentation of gels with gel imaging equipment is an important technique in molecular biology. We provide a range of gel documentation systems for fluorescent imaging from stand alone gel doc systems to more advanced computer driven gel imagers. Most allow the user to take a gel picture then print it out and store the gel image digitally. For chemiluminescence users, there are systems for chemiluminescent detection or multi systems that allow both fluorescence detection and chemiluminescence detection. For basic work, a large range of transilluminators for gel visualisation are also available. These UV boxes provide uniform and bright illumination.
