The BioTek ELx405 Microplate Washer has set the standard in microplate washing based on its superior performance and reliability. This fourth generation product offers several models and options for processing 384- and 96-well microplates to meet all throughput requirements. The unique patent-pending Ultrasonic Advantage option eliminates the number one cause of assay failure - clogged manifold tubes. Valuable time is saved with this automated maintenance capability. All ELx405 Models are available in configurations supporting biomagnetic separation. BioTeks newest ELx405 enhancement offers full plate washing of magnetic microspheres used in a growing number of multiplex assays and bead-based ELISAs.

Programming the ELx405 is easy through its simple keypad interface. For those who prefer the advantages of running instruments via computer control, the ELx405 can be controlled with BioTek's optional Liquid Handling Control Software. The optional BioStack is available for walk-away automation of up to 50 standard height microplates.


  • Magnetic bead assays and standard ELISAs
  • Patented Dual-Action™ manifold
  • The ELx405 HT is the fastest 384-well plate washer available, designed to enhance high throughput operations
  • Extensive onboard software includes independent control of plate position during dispense and aspiration cycles as well as fully programmable fl uid volumes and fl ow rates, shaking, and soaking to lower the CVs of your assay
  • Super low rates in the ELx405 Select CW provide gentle dispense for non-disruptive cell washing
  • Built-in ultrasonic cleaner
  • Easy maintenance with a selection of preprogrammed routines that ensure problem-free operation
  • Fluid detection, fluid flow and vacuum sensors provide complete protection during unattended operations
