Microplate coating and processing systems are used to prepare samples for drug discovery or chemical analysis applications. Microplate coating and processing systems are high-speed production units that stack and feed, clean, dry, dispense or coat sample media, label, and incubate microplates. Microplate coaters or processors are available as complete turnkey systems as well as customizable modular designs. The systems can incorporate microplate washers, barcode label units, material handling units such as conveyors, stacker or feeders, dispensers, coating machines, incubators, storage units and microplate readers. There are many types of microplate coating and processing systems. Example include a microplate dispenser, microplate washer, and a coating machine. A microplate dispenser is widely used in drug discovery and life science research laboratories for dispensing low volume liquid solutions. A microplate washer is a fast and reliable 96-well device for providing very precise fluidic delivery in laboratories. A microplate washer is a versatile device because of its capability of handling user defined wash protocols and plate types. A coating machine is a cantilever type swing out machine that acts as a cooling steel roller for coating on printer material and film rolls. Other microplate coating and processing systems are commonly available.
