This is a fully automatic microplate reader with bichromatic optics. It has on board data reduction calculations which include regressions, curve fittings and cutoff absorbance calculations with step by step user prompting. It includes a large,  non-volatile memory which stores at least 50 user entered tests. It includes parallel and serial outputs (the serial cable is included). It operates with or without a computer and has a bidirectional interface which is available as an accessory for linking to either a Mac or PC.
