This instrument allows for high quality visualization and recording of DNA bands. In addition, the UV Transilluminator can be moved on a rail to allow direct examination of the DNA bands for cases where the gel needs to be cut for isolation of specific DNA bands. The gel images can be easily visualized with the large display on this instrument. The device is equipped with SABZ LadderVision®, a user-friendly and powerful software for gel image analysis and densitometry.
