These Cole-Parmer® Essentials concavity microscope slides feature spherical concavities that enable dry-mounting of large specimens and are ideal for use with specimens that are too thick for conventional slides. Pre-cleaned slides feature ground edges and concavities that are 16 mm in diameter and 0.8 mm deep.

Choose from standard slides that are 1.3 mm thick or thick slides that are 3 mm thick to provide enhanced durability.
