Imagine what would happen to a years worth of data when, say, an annual calibration showed that you might have been using inaccurate pipettes all along!
Obviously, one of the greatest benefits that electronic pipettes bring is the fact that the dispensed quantities will not vary with each individual. The high precision stepping motor automatically moving the piston up and down realizes uniform pipetting for both novice and expert alike, making the results of analyses always reliable.
Meanwhile, you may still have your pipettes inspected and calibrated by an outside facility once a year, or perhaps twice a year, depending on your workplace policies. This is not frequent enough for ensuring the traceability of your pipette accuracy all the time.
With the MPA series, you will be able to perform calibration at your own location whenever you want (patent pending). Deviations in dispensing volume, if any, can easily be corrected by directly inputting the actual dispensed volume measured using an analytical balance. (For this, A&D offer pipette accuracy testers, which automatically perform mass-to-volume conversions.) Further, since this function also corrects errors arising from tip characteristics, you can use other manufacturers tips you prefer and still ensure accurate pipetting.
In addition to the volume (μL) calibration, the MPA series enable calibration and display based on the weight of the sample liquid (patent pending). With the pipette showing the dispensing amount in mg units, it becomes much simpler to handle liquids that need to be managed by weight, such as diluted solutions of solids or powders, as there is no hassle of density calculation.
