This facility contains a powerful Violet LED ( 380-390 nm , 10 W) or UV LED ( 365 nm, 11 W) placed in a special bleaching position that may be used to bleach the samples during a sequence with the Illumination Sequence Editor command. The module is powered by a supply that is built into the Reader, and a connector on the back of the reader connects to the module.
