A combination of angled dispense tubes and both highly adjustable dispense and aspiration rate settings make 405 TS the ideal washer for cell-based assays. The gentle flow rates and side-wall dispensing position ensure the integrity of cell monolayers.

Multiplexed bead-based assays are very common, and 405 TS easily accommodates necessary wash steps. Magnet accessories for biomagnetic separation workflows, available in both flat and 4-zone ring designs, ensure high bead recovery (1). A vacuum filtration module is available for polystyrene bead assays (2).

Manifold tube clogs are the most common source of failure on plate washers. The built-in Ultrasonic Advantage allows the instrument to clean buildup in the manifold tube automatically, without removing it from the instrument.

The Verify Technology option eliminates tedious manual procedures by using an ultrasonic probe (1) to check dispense and aspirate performance. Test results are automatically displayed (2) and indicate tubes that may require additional cleaning.
