To demonstrate the impact of environmental conditions on pipetted volumes, Artel launches the Extreme Pipetting Expedition. During this multi-phase, year-long scientific study, the company will visit locations with extreme ranges of common laboratory conditions, such as high and low temperature, humidity and barometric pressure. Pipette performance will be measured at each location using the PCS (Pipette Calibration System) to identify the resulting volume variability. Artel releases the first set of data collected at Mount Washington, the highest peak in the White Mountains of New Hampshire. At this altitude (6,288 feet) and lower barometric pressure, the pipettes were found to under-deliver by up to 10%. The data highlight the importance of verifying and calibrating pipettes in actual environmental conditions for optimal laboratory liquid handling operations and accurate data. Laboratory managers and technicians can log onto www.artel-usa.com/extreme to view the data and to suggest locations and environmental conditions to be explored in the next phase of the study.
