reagent dispenser solutions at Innovadyne Technologies
Innovadyne Technologies offers the next generation of reagent dispensers for laboratory automation -- non-contact, highly robust, high precision, large dynamic range (nanoliter to microliter) aspirate and dispense instruments. Traditional (flow-through) low-volume liquid handling technologies frequently offer a fixed volume at the expense of accuracy and precision, or a variable volume range at the expense of delivery or dead volume. Classical displacement techniques do not have enough energy to break the surface tension of the last droplet. So a dragging action -- touch off -- is employed, either against the solid surface of a vessel or a liquid surface. Consequently, this technique is highly variable.
Innovadyne's patented microsolenoid-based non-contact liquid handling solution eliminates the need for a touch-off, relying instead on the combined use of rapidly actuated solenoid dispense valves, a controlled pressurized liquid source, and flow path control via hybrid valves. The speed and energy of the fluid displacement enables the surface tension of the liquid to break as it leaves the orifice, eliminating the need for a touch-off. Additionally the isolation of moving parts such as syringes and solenoid valves from the fluid path results in unsurpassed reliability and reproducibility of results. The result is assay miniaturization without loss of precision, enabling researchers to increase throughput while lowering the use of rare or hard-to-produce samples and reagents, and low downtime.
