Over the last 20 years, BioTek has become the leader in microplate washing. This proven expertise in the design and manufacture of the highest quality microplate washers has evolved into the ELx405™ Microplate Washer. Precise, fast and easy to use -- the ELx405 includes a variety of models for washing standard and deep well plates, each with its own innovative features. To meet the ever growing demand for automated washing of microsphere based assays, the industry leading ELx405 Microplate Washer is now available with modules for both vacuum filtration and biomagnetic separation. BioTek's latest ELx405 enhancements offer full plate washing of polystyrene and magnetic microspheres used in a growing number of multiplex assays and bead-based ELISAs, such as those developed on the Luminex® xMAP® technology platform. An available vacuum filtration feature automates the wash steps of filter bottom plates with four adjustable vacuum levels for optical performance with filter pore sizes ranging from 0.45 µm to 1.2 µm. Developed with leaders in genotyping, gene expression and protein assays, the ELx405's biomagnetic separation incorporates high-energy neodymium iron boron magnets for rapid separation of micrometer and nanometer beads with superior retention. The ELx405 Washer is Luminex® xMAP® approved.
