Description:

Drummond’s Pipet-Aid XP pairs a miniature diaphragm pump with ergonomic, fingertip-controlled valves to move liquids cleanly through 1–100 mL glass or plastic serological pipettes. Each aspirate and dispense button rotates to three fixed speeds—Fast, Medium or Slow—letting users snap between rapid bulk transfer and micro-aliquot precision without menu steps. The autoclavable EZ-Grip nosepiece houses a self-locking tissue-culture filter that shuts airflow if wetted, protecting downstream tubing from contamination. A front-door battery compartment grants 30-second swaps of the 8.4 V, 750 mAh NiMH pack, which recharges overnight through the supplied 120 V/60 Hz (or 230/240 V) smart charger; users may work tethered while charging. At just 5.5 in long and 7.5 ounces, the XP fits gloved hands and mounts in its stand or holster between tasks, making it a staple in biosafety hoods and teaching labs worldwide.

Economic Advantage:

The XP’s field-swappable battery and universal 100–240 V charger remove the planned-obsolescence costs of sealed-cell competitors, while its washable internal parts extend instrument life amid harsh bleach protocols. Variable speed buttons cut repetitive-strain downtime, and the auto-shutoff filter prevents expensive decontamination of motors—a single filter replacement (< USD 2) averts full controller loss, yielding one of the lowest cost-per-pipette cycles on the market.
