From Curiosity to Confidence: My Kimble/Kontes KIMAX Volumetric Flask with ST Glass Stopper, Square, Class A, Kimble Chase 28046 900 Review
The Kimble/Kontes KIMAX Volumetric Flask with ST Glass Stopper, Square, Class A, Kimble Chase 28046 900 might not be the typical item found in an outdoor gear specialist’s kit, but precision is critical in many field applications, from environmental sampling to preparing solutions for water purification. This flask, manufactured by Kimble/Kontes, promises accuracy and reliability, making it an intriguing addition to my arsenal of tools. My initial curiosity stemmed from a need for a durable and highly accurate container for mixing solutions while conducting field research on water quality in remote locations.
For years, I’d been using standard plastic containers, but the imprecision and potential for leaching were unacceptable for serious scientific endeavors. I needed something that could withstand the rigors of transport, maintain its calibration, and not contaminate my samples. The Kimble/Kontes KIMAX Volumetric Flask seemed to fit the bill.
Upon unboxing, the first thing I noticed was the robust construction and the distinctive square shape. The KIMAX borosilicate glass felt substantial, and the ground glass stopper fit snugly, suggesting a tight seal. Compared to the cylindrical flasks I’d seen in labs, the square base seemed more stable, which is a huge advantage in a field setting where flat surfaces are rare.
I considered other volumetric flasks, including those from Pyrex and Fisher Scientific, but the square design and the Kimble/Kontes reputation for quality swayed me. My first impression was one of cautious optimism; this wasn’t just a piece of lab equipment, but a potentially invaluable tool for ensuring accuracy in the field. This promised to be a serious piece of kit.
Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flask with ST Glass Stopper, Square, Class A, Kimble Chase 28046 900 to the Test
First Use Experience
My first real test of the Kimble/Kontes KIMAX Volumetric Flask was during a water sampling expedition in the Ozark Mountains. The goal was to prepare a standardized reagent solution for on-site analysis of heavy metal contamination. I needed to accurately dilute a concentrated acid solution, and this flask was crucial.
The flask performed admirably, even in the humid and somewhat uneven terrain. The square base provided excellent stability on a makeshift table, and the glass stopper created a perfect seal, preventing any leakage during mixing. I did have to be careful handling the glass in a rocky environment, but that was a given.
Extended Use & Reliability
After several months of use in varying conditions, including a stint in the desert Southwest and a soggy week in the Pacific Northwest, the Kimble/Kontes KIMAX Volumetric Flask has held up remarkably well. There are no visible signs of wear and tear on the glass, and the graduation mark remains clear and legible. Cleaning is a breeze, even after working with viscous or staining solutions.
Compared to my previous experiences with plastic containers that often warped or became discolored, this flask is a clear winner in terms of durability and reliability. The Kimble/Kontes KIMAX Volumetric Flask has consistently outperformed my expectations and proven itself a worthwhile investment. This has become an essential part of my field kit.
