Elisa washers are laboratory devices designed to control the procedure of washing  samples arranged in plate-based formats. Microplate washers start to dispense, soak and aspirate liquids from the plate in seconds after Users load a plate and select a program. Microplate washers improve the speed and accuracy of different washing procedures, and are particularly useful for Enzyme-Linked Immunosorbent Assays (ELISAs). Microplate washers are also used to wash cell cultures, Western blots, protein arrays, beads and DNA purification protocols.
