These new 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 glass, 25 x 75mm and are 1.1mm thick (compatible with most printers). Frosted marking surface on one end. Packed 72 pieces per plastic box / 1440 per case (20 packs). • Positive charged for cell adhesion • Frosted on one end • Choose 90° or 45° cut corners
