MSE PRO Microscope Slides & Dispenser Microscope slides have a positive charge that makes the surface ideal for cell, tissue and general sample adhesion. Typical samples have a negative charge and are therefore attracted to the positively charged slide surface, significantly reducing “float”. Slides are made of high-clarity, non-polysine treated, soda lime glass and have dimensions of 25×75mm at 1.1mm thick (compatible with most printers). Frosted marking surface on one end. Packed 72 pieces per plastic box / 1440 per case (20 packs). Slides are packaged in a Class 10 cleanroom for ultra-clean, dust-free performance.
