ELx405 Plate Washer

The BioTek ELx405 is a robot-compatible full-plate washer. Agilent describes the ELx405 Select as the first deep-well microplate washer to aspirate and dispense into 96- and 384-well deep-well and standard-height microplates — one washer covering both plate depths.

BioTek is now part of Agilent, so current product information appears under Agilent’s name.

Revolution declares two devices for this washer, and they are different control routes rather than different hardware:

DeviceWhat it runsConnection
ELx405 WasherAn onboard program stored on the instrumentSerial, or URL
ELx405 Washer LHCA protocol in Agilent’s LHC softwareURL

Agilent’s LHC (Liquid Handling Control) software is their stated route for computer control and third-party integration of BioTek washers and dispensers. Which device you use depends on where your wash programs live — on the instrument, or in LHC.

Agilent publishes the following for the ELx405 Select, beyond what’s already in “At a glance” above.

Wash controlPrecise overfill washing with overflow protection
AutomationRobot compatible, full plate washer
SoftwareLHC, for computer control and third-party integration

The Dual-Action manifold is the feature that matters for cell-based work. Independent control of filling and evacuation is what allows overfill washing without losing the cell layer, and Agilent pairs it with low flow rates and angled dispensing for exactly that reason — a monolayer that survives the wash is the point.

  • Run onboard program — run a wash program stored on the instrument
  • Home all axes — return the manifold and stage to their home positions

Home all axes is a recovery operation. A washer left mid-cycle after a fault has its manifold somewhere unknown, and that is not a state to present labware to.

  • Run protocol — run a protocol defined in LHC
  • The programs or protocols the schedule calls must already exist — on the instrument for the onboard route, or in LHC for the LHC route. Revolution runs them; it does not author washes.
  • For the LHC route, LHC must be installed and reachable at the configured URL.
  • Buffer supply and waste must be connected and adequate for the run. A washer that runs dry mid-plate produces plates that look washed and are not.
  • Labware must match what the program expects — a deep-well program and a standard-height plate are not interchangeable.
