Installed on a lab bench or integrated within a robotic system, the ELx405 Select lowers background values and increases important signal-to-noise ratios.

  • Accommodates 96- and 384-deep well microplates as well as ANSI/SBS standard and deep-well plates ≤50mm
  • Polystyrene and magnetic bead assays along with standard ELISAs
  • Patented Dual-Action™ manifold provides independent control of the aspirate and dispense manifolds for precise overfill washing and overflow protection
  • Internal positive displacement pump eliminates the use of troublesome pressure delivery systems and allows the use of any size dispense reservoir
  • Built-in priming trough allows automatic manifold priming and rinsing during both operation and maintenance modes and eliminates the need for blank plates when used in automated robotic systems
  • Fully variable dispense volumes, flow, and aspiration rates provide total control of the washing cycles from a gentle cell-washing application to vigorous wash for high-binding assays
  • Built-in fluid flow, fluid detection, and vacuum sensing provide complete protection for unattended operation
  • BioStack™ compatible for automated washing of up to 50 ANSI/SBS standard height microplates
  • Compatible with Liquid Handling Control Software for additional flexibility
