The 405 TS Microplate Washer is #1 in life science research, known for its excellent performance and outstanding reliability.  The 405 TS has a unique set of features designed to efficiently, effectively wash cell-based assays, microsphere-based assays and ELISA, with outstanding results for every application.  The patented Verify™ technology automatically checks for manifold tube blockages before a wash cycle, and Ultrasonic Advantage™ automatically cleans any blocked manifold tubes. These functions save time and frustration, and ensure successful results.

What's New

Special Offer! Trade in your old ELx405™ Washer and save up to 25% off the purchase of 405™ TS Microplate Washer.


Microplate washing is far from routine when the 405 TS is used. Beyond standard dispense/aspirate protocols, the 405 TS automates liquid handling functions for many applications, including sensitive cell-based assays.
  • Bead washing
  • Cell washing /media exchange  

Cells washed with straight tips
Cell monolayers washed with conventional straight tips can be severely disrupted

Cells washed with angled tips

Patented Verify™ clog detection technology and Ultrasonic Advantage™

Washer verifier

Verify™ technology, which runs an automated QC check for manifold tube blockage, and visually reports any failed wells. The patented Ultrasonic Advantage™ can then be used to automatically and thoroughly clean the aspirate and dispense manifolds.

High resolution, advanced touch screen user Interface


405 TS features high resolution touch screen user interface for intuitive and flexible programming of 96- and 384-well microplate wash protocols. The extensive onboard software seamlessly guides users through protocol development, instrument maintenance and operation.

405 TS

Programmable residual volume

405 TS

The 405 TS onboard software makes it simple to leave the wells empty or with the exact amount of residual your assay needs. Using the dimensions of the selected plate, the software automatically sets the aspiration height to leave the user-specified volume.

Password protection


Protocol critical protocols from unintended changes using the convenient password protection feature in the 405 TS software. Protected protocols can be viewed and run, but not modified by unauthorized users.

405 TS


USB flash drive ports for convenient file transfer and storage

405 TS thumb

Two USB ports on the 405 TS enable convenient file transfer, storage and operation.


Optimized for loosely adherent cell monolayers


The 405 TS can process sensitive cell-based assays with its angled dispense tubes and adjustable flow rates. The Dual-Action manifold and carrier offer X-Y-Z adjustment, perfect for optimizing plate positioning and residual removal for cell-based and other assays.
