Based mostly on Festo’s revolutionary 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 disbursed, the system is ready to calibrate for various viscosities with out person enter. Sooner changeover between liquids results in greater throughput and most system utilization.
Purposes for this closed-loop pipette head embody 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 danger.
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 strain. The DHOP is appropriate with the brand new PGVA-2 strain and vacuum generator, a compact answer for laboratories and not using 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 danger.
The DHOP is appropriate with the simply launched DHAP disposable pipette suggestions. DHAP disposable suggestions stop contamination when dealing with totally different liquids as a result of a brand new tip is robotically used for each pipetting course of. Selecting, sensing, and ejecting – the entire automated dealing with course of for disposable suggestions – is built-in into the DHOP pipette-head system.
DHOP supplies the management system with suggestions on each pipetted quantity for traceability and high quality assurance. The interior controller adjusts the goal quantity and returns the worth achieved to the controller. Stress-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 strain on the system; this permits for smooth allotting with delicate media or higher droplet separation with small volumes.
DHOP benefits embody:
- A single product for the entire quantity vary
- Most precision by means of closed-loop management
- Clever capabilities corresponding to liquid degree detection and a number of allotting
- Full dealing with course of for the disposable suggestions, from detecting tip attachment to automated ejection
- Straightforward commissioning with built-in WebGUI
- Straightforward integration with Festo mechatronic methods for a whole microfluidics answer
Specs embody:
- Pipetting quantity 1…1000 µl
