The 405™ LS Microplate Washer is the fifth generation BioTek washer, known for superior performance and reliability. Built-in automated buffer switching and "quick-change" manifold designs provide improved ease of use and efficiency when washing 96 and 384 well microplates.

Washer maintenance is critical for excellent assay performance, and the 405 LS now offers the new patented* Verify™ Technology for clog detection and patented Ultrasonic Advantage™ for automated manifold cleaning, making the 405 LS a truly 'self-maintaining' system.

The 405 LS has a simple user interface for creation and execution of wash, dispense, aspirate and maintenance protocols within the extensive onboard software. For use under computer control, BioTek’s LHC™ Software is available in standard and 21 CFR Part 11 compliant versions. The optional BioStack™ is available for walk-away automation of up to 50 microplates.

Cell-based assays are easily processed with the 405 Select LS, with its angled dispense tubes, extensive aspirate and dispense rates and plate position controls providing optimal conditions for washing even fragile cell layers.  Magnetic separation and vacuum filtration modules are available for washing magnetic and polystyrene beads used in a growing number of multiplex assays and bead-based ELISAs, such as those developed on the Luminex® xMAP® technology platform. The vacuum filtration feature automates the wash steps of filter bottom plates with five different vacuum levels for optimal performance of filter pore sizes ranging from 0.45 µm to 1.2 µm. The 405 LS is Luminex® xMAP® approved.

A range of configurations for different microplate formats and assay requirements is available for microplate washing, each designed for optimal performance for your plate type and application.
