Microplate Washing Products Span 96- to 1536-Well Densities

The microplate washing product range covers everything from strip washing to full plate washing.

The Biotek (Winooski, VT, USA) product range covers everything from strip washing using the ELx50 to full plate washing with the new 405 Touch and EL406.


The EL406 combines fast, full microplate washing for 96- and 384-well plates along with three reagent dispensers in one compact unit saving bench space and reducing the expense and maintenance of multiple dedicated instruments. Applications include enzyme-linked immunosorbent assay (ELISA), MSD automation, high content screening immunocytochemistry, and magnetic bead assay automation for gene- and protein-expression.

The ELx50 Washer is now a truly flexible platform that provides washing capabilities unsurpassed in its class. Newly available models with biomagnetic separation and vacuum filtration capabilities make the ELx50 an excellent choice for automating the wash steps of 96-well magnetic or polystyrene bead assays, such as those developed on the Luminex (Austin, TX, USA) xMAP technology platform.

Custom magnets, in either flat or ring designs, incorporate high-energy neodymium iron boron magnets for rapid separation of micrometer and nanometer magnetic beads with superior retention. A fast and efficient vacuum filtration module allows the vacuum to be adjusted with a range of settings for flexibility with polystyrene beads when using various filter pore sizes and sample viscosities.

The new 405 Touch Microplate Washer incorporates a high resolution light-emitting diode (LED) backlit touch screen user interface for intuitive and flexible onboard instrument control of 96- and 384-well microplate washing. A 5.7-inch graphical color display seamlessly guides users through protocol development, instrument maintenance, and daily use at the touch of a finger. Two USB flash drive ports enable convenient file transfer, storage, and operation. For those who prefer computer control the 405 Touch can be controlled with optional Liquid Handling Control Software.
