The Drummond Portable Pipet-Aid XL is ergonomically designed to reduce shoulder and neck strain when performing pipetting operations under a hood. This unique pipette controller features a longer handle that lowers the amount of arm lift required to accurately manipulate the pipette tip. The lower, more comfortable arm position reduces operator discomfort and fatigue as well as the frequency of rest interruptions when performing extensive prep protocols requiring multiple aliquoting steps. The ergonomic design of the Pipet-Aid XL also includes an adjustable hand rest and an integrated stand which enables the unit to be easily set down without concern of contaminating the pipette. The Drummond Portable Pipet-Aid XL also features a new quieter, more efficient pump which reduces 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.
