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 offers the utmost in automation flexibility, pace, and suggestions when units deal with many liquids.
Based mostly on Festo’s progressive air-over-liquid fluid dealing with system, the DHOP pipette ensures that aspiration and allotting are unbiased of viscosity. By measuring the stress change when a liquid is aspirated or distributed, the machine is ready to calibrate for various viscosities with out person enter. Sooner changeover between liquids results in larger throughput and most machine utilization.
Functions for this closed-loop pipette head embody pre-analytical pattern preparation of affected person samples, the place liquid properties of the pattern would possibly 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 methods, together with the brand new EXCL multi-axis gantry that lowers engineering, acquisition, and meeting prices whereas growing machine capabilities.
Within the Festo air-over-pressure system, liquid aspirates into the disposable tip utilizing vacuum and dispenses utilizing stress. The DHOP is suitable with the brand new PGVA-2 stress and vacuum generator, a compact resolution for laboratories and not using a central compressed air provide. A single PGVA-2, which permits the stress 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 stop contamination when dealing with completely different liquids as a result of a brand new tip is robotically used for each pipetting course of. Choosing, sensing, and ejecting – the whole automated dealing with course of for disposable ideas – is built-in into the DHOP pipette-head system.
DHOP offers 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. Strain-based liquid degree detection previous to aspiration ensures most precision. Any foam on the floor is ignored in degree detection. The liquid velocity is adjusted by altering the stress on the system; this enables for delicate allotting with delicate media or higher droplet separation with small volumes.
DHOP benefits embody:
- A single product for the whole quantity vary
- Most precision by way of closed-loop management
- Clever features comparable to liquid degree detection and a number of allotting
- Full dealing with course of for the disposable ideas, from detecting tip attachment to computerized ejection
- Straightforward commissioning with built-in WebGUI
- Straightforward integration with Festo mechatronic methods for an entire microfluidics resolution
Specs embody:
- Pipetting quantity 1…1000 µl
