Since 1932 UVP has been involved in developing solutions, particularly for those who work in the ultraviolet portions of the spectrum. Since the 1960's there has been dramatic growth in the area of genetics research and UVP recognized opportunities to develop products for this industry. In particular UYP developed their own devices to facilitate visualizing and imaging the separation of the mixture's components on the Agarose gel medium in which this is typically processed. Some of the analyte molecules fluoresce under ultraviolet light, so with their long experience in the ultraviolet field the team UVP developed their line of Transilluminators that back illuminate subjects. Combining their Transilluminators with other devices they developed GelDoc (Gel Documentation) imaging systems; integrated and stand-alone devices used in molecular biology laboratories for the imaging and documentation of nucleic acid (DNA and RNA) and protein polyacrylamide or agarose gels.

On this page Company Seven presents an index of some of the less well known, but no less important accessories that facilitate working with gels and obtaining accurately exposed images.
