All About the Kimble/Kontes KIMAX Micro Volumetric Flasks with ST Glass Stopper, Cylindrical, Class A, Serialized and Certified, Kimble Chase 28017A 5: Start Here
The Kimble/Kontes KIMAX Micro Volumetric Flasks with ST Glass Stopper, Cylindrical, Class A, Serialized and Certified, Kimble Chase 28017A 5 is a precision instrument designed for accurate measurement and storage of small volumes of liquids. Manufactured by Kimble Chase, these flasks feature a cylindrical body for efficient mixing, a ground glass stopper to prevent contamination, and individual serialization for traceability. They are Class A certified, meeting stringent quality standards.
As an experienced outdoor and tactical gear specialist, my work sometimes involves analyzing water samples in the field, requiring precise measurements for reagent preparation. Traditional volumetric flasks are often too large for my needs, leading to wasted reagents and increased logistical burden in remote locations. The need for a highly accurate, small-volume flask is what drew me to the Kimble/Kontes micro volumetric flask.
Upon unboxing, I was immediately impressed by the flask’s solid construction and the snug fit of the ground glass stopper. The glass felt thick and durable, reassuring me that it could withstand the rigors of field use. The cylindrical design seemed more practical than the bulbous shape of some other flasks, offering a stable base and easier sample retrieval.
I had considered cheaper, non-certified alternatives, as well as larger, more general-purpose flasks. Ultimately, I chose the Kimble/Kontes flask for its combination of small volume, Class A certification, and cylindrical design – features crucial for accurate field analysis. My initial reaction was excitement tempered by the price, but hopeful that the performance would justify the investment.
Real-World Testing: Putting Kimble/Kontes KIMAX Micro Volumetric Flasks with ST Glass Stopper, Cylindrical, Class A, Serialized and Certified, Kimble Chase 28017A 5 to the Test
First Use Experience
I tested the Kimble/Kontes flask during a recent water quality assessment expedition in the Alaskan backcountry. The primary use was preparing precise dilutions of chemical reagents for on-site water testing. The flask performed flawlessly in a variety of conditions.
The conditions ranged from moderate rainfall to dry, dusty environments. The ground glass stopper sealed tightly, preventing contamination from both moisture and particulate matter. The cylindrical shape proved easy to handle, even with gloved hands, and the narrow neck facilitated precise filling.
The flask was easy to use. The graduation ring was clear and distinct, and I quickly became comfortable accurately filling to the 5mL mark. The flask exceeded my expectations, delivering consistent and reliable measurements from the first use.
Extended Use & Reliability
After several months of intermittent use in the field and in the lab, the Kimble/Kontes flask has held up remarkably well. There are no signs of chipping or cracking in the glass, and the stopper still fits snugly. I have even accidentally dropped it once onto a hard surface from a low height, and it survived unscathed.
The only noticeable wear is some minor scratching on the exterior of the glass from storage and transport in a field kit. The flask is very easy to clean. A simple rinse with distilled water and a mild laboratory detergent is all that’s required to remove residue and maintain its accuracy.
Compared to my previous experiences with less expensive glassware, the Kimble/Kontes flask is a clear winner. Its superior build quality, accurate calibration, and reliable performance make it an invaluable tool for field research.
