Abstract
A manually directed, electronic multi-channel pipettor uses servo controlled motors to drive a carriage and pipetting head in response to a user's manipulation of a control handle. The pipetting head include an array of tip fittings, e.g. 96. The system includes a check processor to avoid unintended motion in case of system faults or crashes. The system requires substantial force to attach the array of tips, and therefore includes controls that require both of the user's hands be occupied during the tip attachment process.
