The Honest Truth About the Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 22
As an outdoor and tactical gear specialist with over a decade of experience, I’ve handled everything from high-tech night vision to the most basic survival tools. One area often overlooked, but critical in many field applications, is proper sample collection and handling, and that’s where tools like the Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 22 come in. These aren’t your everyday dropper; they are precision instruments for anyone serious about field research, water testing, or even advanced wilderness medicine.
My journey to these pipets began with a frustrating search for reliable equipment for water purity testing during extended backcountry expeditions. I needed something durable, accurate, and reusable, as disposable plastic options were simply not environmentally friendly or practical for remote locations. I was tired of inaccurate measurements and the fragility of makeshift sampling methods.
Upon unboxing, the first thing that struck me about the Kimble/Kontes pipets was the robust feel of the glass. They felt significantly more substantial than the thin, disposable plastic alternatives I was accustomed to. The color-coding was also a welcome addition, offering a practical way to quickly identify different pipets in a kit.
Compared to basic laboratory droppers, these are in a different league. The Kimble/Kontes pipets felt more precise than the generic plastic transfer pipettes I’ve used in the past, and their glass construction promised better chemical resistance than either plastic or some less robust glass alternatives. While I also considered graduated cylinders, the pipets were more suitable for the small volumes I typically work with in the field.
Initially, I was cautiously optimistic. I was excited about the potential for increased accuracy and reusability but also concerned about the fragility of glass in rugged outdoor environments. The Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 22 promised a step up in reliability and accuracy, but I needed to see how they performed in the real world.
Real-World Testing: Putting Kimble/Kontes KIMAX Reusable Bacteriological Pipets, Glass, Color-Coded, Kimble Chase 37079 22 to the Test
First Use Experience
My first opportunity to test the Kimble/Kontes pipets came during a week-long water quality assessment trip along the Buffalo River in Arkansas.
