The Pipette Checkit ® is a tool to identify potential volume delivery errors for pipettes. The Company is a provider of an intelligent operations management platform for deskless workforces, enabling operational agility and. If your institution requires pipette calibration on a specific schedule, you should adhere to this schedule and use the CheckitĪs an extra verification step between scheduled calibrations. Checkit plc is a United Kingdom-based holding company. Expected performance at different volumes #Checkit ipaper verification# When a pipette is used near the bottom of its range, the measured volumes will vary more, and are also more strongly affected by slight variations Piston pipettes are most accurate at or near their nominal volume (the maximum volume the pipette can deliver). In pipetting style or environmental factors like humidity. The markings on the Checkit reflect this variation.Ī note on environment: One advantage of the Checkit is that it can be used in the same room in which the experiment will be conducted. Checkit is the Intelligent Operations platform that gives operational leaders up-to-the-minute information and control over their deskless workforce. This can help identify variation in delivered volume due to pressure, humidity, or temperature differencesīetween the calibration environment and the experimental environment. Because the Checkit directly measures delivered volume rather than relying on gravimetric analysis, there is also no need to use correction calculations that account for these factors. Most pipette manufacturers provide specifications for both the accuracy and precision of their pipettes. Certainty ensures compliance, reduces risk, and improves. Briefly, accuracy describes how close the mean of delivered volumes is to the stated volume, and precision describes the distribution of the volumesĪround the mean. Inspection software to easily collect and report inspection data and resolve issues identified. If you choose to compare your Checkit readings to the manufacturer’s specifications, remember to account for both accuracy and precision when determining what range is acceptable.
