Microliter Electronic Pipette
INTEGRA's 50 μL head enables the VIAFLO 96/384 to uniquely offer optimized pipetting performance in five volume ranges 0.5 to 12.5, 2 to 50, 5 to 125, 10 to 300 and 50 to 1250 μLs. Accommodating pipetting heads that are quickly and easily interchanged enables investment in a single base unit rather than multiple units as would be required by other systems to achieve optimized performance at different pipetting volumes from 0.5 to 1250 μL.
Good pipetting practice for any air displacement pipette recommends that users work in a volume range of 30 to 100 percent of nominal volume because performance specifications change with decreasing volume. Additionally, working in the optimal volume range is less dependent on operator and environment conditions. This also applies to pipetting heads. Most handheld pipettes and pipetting heads are based on the same physical principle - air displacement. The smaller the sample volume relatively to the full stroke volume, the more dead air will be in users' pipetting system. Air as a gas is influenced by physical parameters such as temperature, humidity and pressure. Therefore the more air inside the pipetting system the larger the influence of those parameters resulting in a negative impact upon the accuracy and precision of pipetting results.
With the handheld electronic pipette, users can always work in the optimal volume range, simply by exchanging the pipetting head. This leads to more accurate and reproducible pipetting results in the lab, where conditions are usually not as stable as in a fully climate controlled calibration environment.
The pipette is a handheld 96- / 384-channel electronic pipette that enables fast, precise and easy transfer of 96 or 384 samples simultaneously. Uniquely it offers all the benefits of increased sample throughput as well as lower sample and reagent use without the expense of having to invest in a robotic liquid handling system. The electronic pipette has been designed to be used just like a standard handheld pipette. Therefore, no special skills or training are required to operate it. Servo assisted motor steering ensure that operating it is both effortless and precise. The pipette features the company's popular Touch Wheel pipette user interface enabling simple and fast programming of a wide range of pipetting modes including repeat dispense, serial dilute and mixing routines.
The pipette comes with 10 pre-defined pipetting modes enabling the system to be used productively almost immediately. A further 40 user designated custom programs allow even the most diverse and complex pipetting operations.
