Enabling researchers to view and capture fluorescent gel images, photodocumentation systems are designed for fluorescence imaging. These systems include a transilluminator, filter, camera, and darkroom settings via the use of a small hood or enclosed doors. Applications include fluids contamination, microbiology studies, antibiotic testing, and hygiene studies. High-resolution cameras deliver photographs in either black and white or full colour, and the images can be saved to a memory card or printed directly from most units.
