Let’s Dive into Corning Pipettor 2-20ul Autoclavable 4072
The Corning Pipettor 2-20ul Autoclavable 4072 isn’t exactly the kind of gear that gets your adrenaline pumping like a new rifle or a custom-made knife. However, in my line of work—testing and evaluating everything from high-end optics to field-expedient water filtration systems—precise liquid handling is absolutely critical. This Corning pipettor promises accuracy and reliability in a small volume range, something that’s essential for preparing solutions, calibrating sensors, and even analyzing samples collected in the field.
I was tired of relying on inaccurate, cheap pipettes that consistently yielded inconsistent results. I needed a pipettor that offered precision and durability, capable of withstanding frequent use and sterilization. The Corning Pipettor 2-20ul Autoclavable 4072 seemed to fit the bill, promising both accuracy and the ability to be autoclaved for sterile applications.
Unboxing the pipettor, my first impression was positive. The build quality felt solid, despite its light weight. The materials didn’t feel cheap or flimsy, and the plunger moved smoothly, suggesting a well-engineered mechanism.
Compared to some cheaper, generic pipettors I’ve used, the Corning model instantly felt more refined. Unlike a fixed volume pipettor, the adjustable nature of the Corning Pipettor 2-20ul Autoclavable 4072 gives it much better versatility than a single volume pipette and the autoclaving capability puts it far ahead of most low-cost options. I was cautiously optimistic, hoping it would live up to its promise of precision and durability.
I was definitely excited to put it to the test, and even hopeful that it would eliminate the inconsistencies I’d been experiencing.
Real-World Testing: Putting Corning Pipettor 2-20ul Autoclavable 4072 to the Test
First Use Experience
I tested the Corning Pipettor 2-20ul Autoclavable 4072 in my small, make-shift lab, simulating conditions similar to a field research setup. I needed to prepare several serial dilutions of a standardized solution for calibrating a water quality sensor I was reviewing. This involved accurately transferring volumes ranging from 2ul to 20ul.
The pipettor performed beautifully. The adjustments were easy to make, and the digital display was clear and easy to read. I found the plunger action to be smooth and consistent, making it easy to dispense precise volumes.
Initially, I found the ergonomics of the pipettor to be comfortable, but after prolonged use, the plunger requires a bit more force than I would expect, which may cause hand fatigue for some users. The tip ejection mechanism worked well, easily releasing the tips without requiring excessive force. Even with this slight problem, it was far more reliable than the cheaper pipettes I had been using.
Extended Use & Reliability
After several weeks of consistent use, the Corning Pipettor 2-20ul Autoclavable 4072 has continued to perform well. I’ve used it to prepare numerous solutions, analyze water samples, and even mix reagents for a field-expedient explosives detection kit I was evaluating. It has been a key piece of lab equipment.
So far, the pipettor shows no signs of wear and tear. The plastic body remains intact, and the plunger action is still smooth. Regular cleaning is necessary, and I always clean the tip before and after.
Maintaining it is simple: a quick wipe-down with a lint-free cloth and occasional lubrication of the plunger mechanism keeps it running smoothly. Compared to my past experiences with unreliable pipettes, this Corning model is a significant upgrade.
