An improved liquid handling device used for transferring a selected quantity of liquid from one receptacle to another. The device includes a meniscus tracking feature which minimizes mixing in a liquid sample and contact between the sample and a sample-handling pipette during a liquid-transfer operation. Further included is a volume-correcting feature for improving the accuracy of volume withdrawn into or dispensed from the pipette during a liquid handling operation.

A method for reducing the difference between actual and specified amounts of liquid being transferred by an automated device from one receptacle to another comprising representing the actual amount of liquid transferred by such automated device as a polynomial expression whose variable terms represent corresponding specified amounts of liquid withdrawn, using data pertaining to actual transfer volumes to solve for the polynomial expression, using the solved expression to determine a correction factor between actual and specified amounts of liquid to be withdrawn, and applying the correction factor to the automated device to correct the amount of liquid transferred by such automated device to reduce the difference between actual and specified liquid amounts.
