The Drummond Portable Pipet-Aid XL has a long lightweight handle that lowers the arm lift required to perform pipetting operations. This more comfortable arm position reduces shoulder and neck strain, particularly when working under a hood. An adjustable hand rest and a removable stand enable the unit to be set down without contaminating the pipette. A quiet, efficient pump reduces background noise and extends operation period between charges. The unit can be charged while being used to eliminate downtime. Three-speed settings provide more precise control for both aspirate and dispense modes.
