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, durable, and cellophane wrapped.
