Bio-Rad Bio-Plex Pro II Wash Station

This used Bio-Rad Bio-Plex Pro II Wash Station is an automated microplate washing system designed specifically to support magnetic bead based multiplex assay workflows alongside Bio-Plex reader platforms. The unit has been checked for proper mechanical and fluidic operation and is ready to be reintroduced into a laboratory workflow. The Pro II Wash Station uses a magnetic carrier to hold beads securely in place during aspiration and dispense cycles, which minimizes bead loss and improves assay reproducibility compared to manual washing methods. It automates the repetitive washing steps required in bead-based immunoassays, reducing hands-on time and helping standardize results across runs, plates, and operators. Laboratories running Bio-Plex multiplex assays for cytokine profiling, biomarker discovery, or other bead-based immunoassay applications rely on a dedicated wash station like this to maintain consistent assay quality at scale. This pre-owned Pro II Wash Station offers that same automated, bead-safe washing capability to labs looking to add or replace equipment without the cost of a new system.
