The SlideFolder will hold up to twenty standard microscope slides 75mm x 25mm (3x1in.) 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 base is available in 5 different colors, allowing color-coding classification of the slides. Each slide location is identified with a number from 1 to 20. Removal of slides is made easy simply by pressing on one end, which will automatically lift the other end. The two transparent hinged covers offer a full view of each slide without having to remove it from its position in the SlideFolder and allows easy reading of ID labels with or without an optical bar code reader. All units are stackable and take minimum space on laboratory tables or shelves. Will resist temperatures between -80 C and +80 C. Not autoclavable.
