Designed for examining larger tissue samples, the mega-sized microscope slides feature bigger dimensions, and deliver larger experimental surface over the standard-sized microscope slides of 25.0mm×75.0mm. Poly-Ly-Sine coated, PLUS coated and AdStar coated mega-sized microscope slides are also supplied for more reliable use with the problematic tissue specimens such as neuro, breast and fatty tissues, as well as orthopedic specimens such as femoral heads. All the PorLab® mega-sized microscope slides are optimally pre-cleaned and ready-to-use.
