Microscope Slide, Plain End, 1,2mm thick, 25x75mm, 144 pieces

Microscope Glass Slides - Esco

Our microscope glass slides are manufactured by Esco - Erie Scientific Co, where reliability and quality are recognized to be the best.
Made from the highest quality glass sheets.
The dimensions of the slides have been standardized to millimeters according to the U.S. government Specifications.
They are packed with care to assure cleanliness.
The glass is fully annealed to minimize chipping.

Our microscope glass slides are precleaned and are made from clear-white glass. They are individually inspected and free from moisture, dirt, and film. All of our slides are flat, uniform and durable. They are packed 72 slides/box and cellophane wrapped.
