Festo introduces the DHOP closed-loop pipette head for high-speed robotic pipetting purposes requiring constant volumes over a variety of liquid viscosities. The DHOP pipette head gives the utmost in automation flexibility, velocity, and suggestions when gadgets deal with many liquids.
Based on Festo’s progressive air-over-liquid fluid dealing with system, the DHOP pipette ensures that aspiration and allotting are impartial of viscosity. By measuring the strain change when a liquid is aspirated or allotted, the machine is ready to calibrate for various viscosities with out consumer enter. Faster changeover between liquids results in larger throughput and most machine utilization.
Applications for this closed-loop pipette head embrace pre-analytical pattern preparation of affected person samples, the place liquid properties of the pattern may change affected person to affected person. Festo Life Science personnel work with OEMs from inception to implementation, which brings merchandise to market sooner, with much less engineering overhead and threat.
The DHOP closed-loop pipette head seamlessly integrates with Festo’s world-class mechatronic techniques, together with the brand new EXCL multi-axis gantry that lowers engineering, acquisition, and meeting prices whereas rising machine capabilities.
In the Festo air-over-pressure system, liquid aspirates into the disposable tip utilizing vacuum and dispenses utilizing strain. The DHOP is suitable with the brand new PGVA-2 strain and vacuum generator, a compact resolution for laboratories with out a central compressed air provide. A single PGVA-2, which permits the strain provide to be centralized, can function as much as 8 DHOP. Festo designs its parts, such because the EXCL, PGVA-2, pipettes, and different parts, to interoperate, which reduces engineering and lowers threat.
The DHOP is suitable with the simply launched DHAP disposable pipette ideas. DHAP disposable ideas forestall contamination when dealing with totally different liquids as a result of a brand new tip is routinely used for each pipetting course of. Picking, sensing, and ejecting – the whole automated dealing with course of for disposable ideas – is built-in into the DHOP pipette-head system.
DHOP gives the management system with suggestions on each pipetted quantity for traceability and high quality assurance. The inner controller adjusts the goal quantity and returns the achieved worth to the controller. Pressure-based liquid stage detection previous to aspiration ensures most precision. Any foam on the floor is ignored in stage detection. The liquid velocity is adjusted by altering the strain on the system; this enables for delicate allotting with delicate media or higher droplet separation with small volumes.
DHOP benefits embrace:
- A single product for the whole quantity vary
- Maximum precision by way of closed-loop management
- Intelligent capabilities corresponding to liquid stage detection and a number of allotting
- Complete dealing with course of for the disposable ideas, from detecting tip attachment to computerized ejection
- Easy commissioning with built-in WebGUI
- Easy integration with Festo mechatronic techniques for a whole microfluidics resolution
