Dual-Action™ Manifold

BioTek’s dual-action manifold design allows independent control and positioning of both the aspirate and dispense sections of the manifold, providing three major benefits:

1. Rapid washing of either 96- or 384-well plates on one platform
2. Ideal positioning for gentle washing of sensitive cell-based assays and
3. Overfill/overflow washing with continuous fill and aspiration at the tops of the wells, vigorous washing for ELISA assays.

BioTek's dual-action manifold allows independent control of dispense and aspirate tubes for optimal x-, y- and z- positions. Dispense tubes are angled to 20° for gentle dispensing into well containing delicate cell layers.

BioTek’s 405 Microplate Washer and EL406 Washer Dispenser incorporate the dual-action manifold in standard or optional configurations. As cell-based assays become more prevalent, the benefits of the dual-action manifolds with their angled tubes are more important. The angled dispense tubes can be positioned to provide a gentle flow down the sides of a 96- or 384-well plate so as not to disrupt the cell layer.

Dual-Action Manifold Benefits:

• Wash 96- and 384-well microplates on one instrument without changing the manifold
• Optimal positioning of aspirate tubes for more or less residual after dispense
• Optimal positioning of dispense tubes for cell-based assays or for standard washing
• Angled dispense tubes won’t disrupt cell layers
• Allows vigorous overfill/overflow washing
