The Kimble/Kontes KIMAX Kohlrausch Volumetric Flasks, Class A, Kimble Chase 28100 100 Review No One Else Gives You
Let’s be honest, volumetric flasks don’t exactly scream “tactical gear.” But hear me out, because precise measurement is crucial in many outdoor applications, from water purification to DIY chemistry for survival situations. The Kimble/Kontes KIMAX Kohlrausch Volumetric Flasks, Class A, Kimble Chase 28100 100, with its Class A accuracy and specialized design, might just be the unsung hero of your precision kit.
My journey to this particular flask wasn’t born of a need to measure exactly 100mL of tactical-grade whiskey, although the thought did cross my mind. I needed a precise and reliable tool for mixing disinfectant solutions for sanitizing gear after exposure to potentially contaminated environments in the field. The inherent accuracy and specifically designed wide mouth of this flask promised a level of precision and ease of use that other options lacked.
Upon unboxing, the immediate impression was one of quality and deliberate design. The glass felt substantial, the graduation mark was crisp and clear, and the enlarged mouth hinted at the ease of use it promised. Compared to standard, narrow-mouthed volumetric flasks, or even graduated cylinders, the Kimble/Kontes flask felt purpose-built for the task at hand.
I chose this flask over cheaper alternatives (often made of plastic) because of the superior chemical resistance and thermal stability of borosilicate glass, as well as the guaranteed accuracy of a Class A volumetric flask. Initial impressions were positive, and I was excited to see how it performed in the field.
Real-World Testing: Putting Kimble/Kontes KIMAX Kohlrausch Volumetric Flasks, Class A, Kimble Chase 28100 100 to the Test
First Use Experience
My first test involved preparing a bleach solution for decontaminating some hunting gear after a scouting trip in a swampy area. I set up a makeshift lab bench on the tailgate of my truck. The Kimble/Kontes flask made adding the bleach concentrate remarkably easy compared to pouring from a container into a narrow graduated cylinder.
The blasted graduation ring stood out even in the subdued light of dusk, making accurate measurement simple. There were no issues with visibility, and the flask sat stable on the slightly uneven surface of the tailgate.
Extended Use & Reliability
After several weeks of regular use for preparing disinfectant solutions and other field chemistry tasks, the Kimble/Kontes flask has proven to be exceptionally reliable. I’ve cleaned it numerous times with various solvents and detergents without any noticeable degradation of the glass or the graduation mark.
The flask has held up surprisingly well, considering the somewhat rough handling it receives during transport and storage in my gear locker. While I always take care with glassware, the Kimax borosilicate seems more resistant to minor bumps and scratches than other labware I’ve used. It outperforms plastic alternatives by a mile, which often stain or warp after repeated exposure to harsh chemicals.
