Superfrosted end microscope slides

Microscope slide with a superfrosted end. These slides have one frosted side with a brilliant white opaque coating that will take and retain all pen markings. They offer superior readability and they are permanent. Microscope glass slides are manufactured by Esco - Erie Scientific Co, where reliability and quality are recognised to be the best.Made from the highest quality glass sheetsThe dimensions of the slides have been standardised to mm according to the U.S. government SpecificationsThey are packed with care to assure cleanlinessThe glass is fully annealed to minimise chippingOur 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.Chemical Makeup
