ELx50 Microplate Strip Washer

BioTek's years of experience in the development of both microplate washers and automated systems for EIA applications has culminated in the ELx50™ Auto Strip Washer. As a self contained and programmable instrument, the ELx50 allows for full control of precise fluidic delivery from the gentle dripping of a simple squeeze bottle to the full force of pressure delivery systems.

The ELx50 is a fast and versatile automated strip washer which can come equipped with our patented Dual-Action™ 16-channel manifold. This breakthrough design allows for independent control of the dispense and aspiration manifolds for overfill washing and overflow protection in both 96- and 384-well formats. The problem of fitting dispense and aspirate tubes into a much smaller 384-well is solved with the ELx50.

Additionally, in a 96-well format, the Dual-Action manifold provides incomparable wash performance with two sets of dispense and aspiration tubes per well. This exclusive method of two-fold aspiration guarantees low residuals. The ELx50 Auto Strip Washer is the perfect solution for low volume users of both 96- and 384-well microplates.

Now, BioTek has expanded their popular microplate washing product line with the ELx50 Filter Microplate Washer (FMW). The ELx50 FMW model, for use with filter-bottom microplates, allows a user to process important multiplex bead assays, widely used in many diverse applications. With a unique vacuum grate and bottom aspiration, bead assays are quickly, efficiently and reliably washed. The aspiration carrier can be adjusted for optimal performance with filter pore sizes ranging from 0.45 μm to 1.2 μm. Exchange the vacuum carrier for the included standard carrier, and the ELx50 FMW is ready to wash traditional ELISAs and cell-based assays.

In addition to washing multiplex bead assays, the ELx50 FMW is well-suited to work with filtration-to-waste processes such as PCR cleanup after DNA amplification to remove unwanted residues or reaction by-products with filtrate.




The ELx50 Filter Microplate Washer provides a 96-well
microplate vacuum filtration option for filter bottom plates




The Liquid Level Alert™ option allows users the convenience of continuous
monitoring for both supply and waste bottles. At the beginning and end of a
wash protocol, the liquid level is verified to ensure sufficient wash buffer remains
in the designated dispense bottle to complete a microplate wash. Sufficient
storage capacity in the waste bottle is also verified.




The ELx50/16 offers incomparable wash results via
two sets of dispense and aspiration tubes per well in
96-well format.
