Millennium 500 is the new unique processor for the filling of 96 and 384 well microplates. It is designed to provide fast and reliable microplate filling with high precision and repeatability, whilst allowing flexibility to accommodate various custom requirements. Up to two different reagents can be filled simultaneously or sequentially with user adjustable incubation period between the fill sessions. The Millennium 500 is primarily designed to fill a 96 well or a 384 well microplate but can be configured at the time of production for deep well microplates and tubes.
