The EZSPHERE Microplate 96 well dish is a product manufactured by Asahi Glass Company, for culturing of mammalian cells and the preparation of 3D cell spheroids. The dish size (diameter measurement) is designated in the product title and it contains about 14000 microwells on the surface of the plate. Each plate is individually laser-etched and provided in a sterile, ready-to-use format. The plates are made of polystyrene material that is coated with a biocompatible non-adherent surface. Mammalian cells will "slide" to bottom of the wells by gravity and aggregate with neighboring cells according to their biologically programmed narrative.
