The SlideFolder will hold up to twenty standard microscope slides 75mm x 25mm (3" x 1") and is made of two parts: a base holding the slides horizontally, offering numbered spaces for easy identification, and transparent doors which can either cover the slides or be swung behind the SlideFolder for space-saving purposes. The two transparent hinged covers offer a full view of each slide without having to remove it from its position in the SlideFolder, and allow easy reading of ID labels with or without an optical bar-code reader. All units are stackable and take minimal space on laboratory tables or shelves.
