I put the pipettor through its paces with various aqueous solutions, including buffers and cell culture media, aiming for both high and low volumes within its specified range. The dispensing action was consistently smooth, and I noticed a distinct lack of the “dead volume” that often plagues lesser pipettes, contributing to more accurate aspiration and dispensing. The separate push buttons for dispensing and tip ejection proved invaluable, minimizing the risk of accidental tip ejection or volume alteration.

The “glove-friendly” JustTip* adjustable tip ejector was a feature I immediately appreciated. Even with nitrile gloves on, the ejection mechanism was easy to engage, and it worked flawlessly with a variety of standard pipette tips. Throughout the first day, involving over fifty pipetting cycles for various experiments, the pipettor performed without a hitch, maintaining its accuracy and smooth operation. There were no surprising quirks or unexpected issues; it simply performed as advertised.

Extended Use & Reliability

Weeks have now turned into months, and this variable volume pipettor has become my go-to instrument for routine lab tasks. It’s been used daily for DNA extractions, PCR setup, serial dilutions, and reagent preparation, accumulating hundreds, if not thousands, of pipetting actions. The build quality has held up exceptionally well, with no discernible wear on the plunger assembly or the body of the instrument.

The volume setting locks are a revelation; once set, the volume remains precisely where it’s supposed to be, preventing those accidental nudges that can ruin a critical assay. Autoclaving the unit without disassembly, as advertised, has been a huge convenience, simplifying the sterilization process between critical experiments or after contamination events. Even after multiple autoclave cycles, its performance has remained consistent, with no signs of degradation.

Compared to some of my older, more finicky pipettors that required frequent recalibration checks, the Wheaton Socorex Acura has significantly reduced my maintenance overhead.
