The BioTek EL406 washer dispenser is a compact instrument offering fast, full plate washing along with three reagent dispensers. The EL406 capabilities include washing and dispensing for standard assays, plus biomagnetic separation and vacuum filtration protocols. The Dual-Action manifold optimizes washing for loosely adherent cell monolayers. The patented Ultrasonic Advantage prevents blockages in the manifold tubes before washing, to reduce assay failure. This modular plate washer dispenser offers flexibility with both syringe pump and peristaltic pump dispensers, along with plate washing, on a single platform.


Applications for the EL406 Washer Dispenser run from simple dispense operations to full-scale automation of liquid handling steps in preparation for downstream processes. Here are a few important applications of the EL406.
  • Bulk reagent dispensing
  • Cell seeding

Automate Your Workflows

Expand your workflow automation by integrating the EL406 with BioTek’s range of robotics, including the BenchCel Microplate Handler, BioStack™ Microplate Stacker and BioSpa™ Automated Incubator. See this Tech Note describing benchtop ELISA automation with the BenchCel, EL406 and Synergy Neo2.



Washing and multiple reagent dispensing


There’s no need for multiple instruments when you have an EL406 in the lab! The EL406 is microplate washer with peristaltic and syringe pump modules available to make it into an efficient multi-tasking system. For benchtop use or integrated into automated systems, the EL406 does the work of multiple instruments.

96-, 384- and 1536-well plate compatible


BioTek’s Dual-Action™ manifold quickly washes 96- and 384-well plates. For 1536 washing, unique aspirate and dispense manifolds rapidly dispense and aspirate across the plate. Wash speeds for the three plate types range from 13 seconds to 36 seconds, keeping all your processes efficient.



Gentle processing for cell-based assays


Cell-based assays can be challenging to wash - too often, cell monolayers are disrupted by vigorous dispensing or overly intense aspiration. The EL406 Dual-Action manifold and plate carrier have x-y-z adjustments, and flow rates are fully adjustable - to optimize parameters for even the most sensitive assays. Angled dispense tubes direct fluid flow to the well sides, further minimizing disruption.


Bead washing: magnetic and polystyrene


The EL406 is a powerhouse for many standard plate washing and dispensing protocols, but it also automates more complex operations like magnetic and polystyrene bead washing workflows – and it’s Luminex® xMap® approved. Bead washing is available for 96- and 384-well microplates.


Easy maintenance with Ultrasonic Advantage™


EL406 has a number of automated system maintenance features, including. BioTek’s Ultrasonic Advantage™. The dispense and aspirate tubes are immersed into the built-in ultrasonic bath in the priming trough while the automate cleaning program runs, dislodging and aspirating away salt crystal and protein buildup in the tubes.
