Box of Single 72 (Well) Concave Slides
Single concave glass slides are ideal for studying live micro organisms because of a single depression well in the middle of the slide. The dip is .5 mm to .8 mm deep which is perfect for viewing liquids like pond water. Larger organisms won't be damaged or squashed when you apply the slip cover and the water is prevented from drying out as quickly as with a plain glass slide. This reusable microscope slide has ground edges and measures 1" x 3" and is 1 mm to 1.3 mm thick.
