BIOVIEWER [Microscope]: Image magnification for ‘Biosets

The Bioviewer, made from tough, almost unbreakable plastic to give years of use in classroom conditions. Designed specifically with magnification set and ready to view microscope images on a film slide. (See Biosets). A white reflector stage provides sufficient light for a bright image. No need for a microscope lamp so use at any time, in any room even outdoors. Inevitably, It isn't necessary to leave expensive microscopes in inexperienced hands.
