Microplate washers are designed for effortless use with 96- or 384-well plates in routine ELISA applications. Intuitive graphical user interface makes each assay extremely easy to set up. Context-specific help features ensure that protocols are developed quickly and easily, with minimal user training required. Other microplate washer benefits include walk-up usability, flexibility in well plate size, automated rinse in some models to reduce clogging, and cross-wise aspiration to reduce residual volume within each well.
