I also considered flasks from Pyrex, another reputable brand, but ultimately chose the Kimble/Kontes due to its competitive price point for a Class B certified flask with a glass stopper.
My initial reaction was a mix of relief and anticipation. I was relieved to finally have a reliable tool. I was also eager to put it to the test to ensure its accuracy lived up to the Kimble/Kontes reputation.
Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Class B, Kimble Chase 28015 10 to the Test
First Use Experience
My first test involved creating a standard solution of sodium hypochlorite for water disinfection. This required dissolving a precise amount of concentrated bleach in distilled water to reach a specific concentration. The testing was done in my workshop, which, while not a pristine laboratory, provides a controlled environment for solution preparation.
The flask performed flawlessly even with the sometimes-fluctuating temperatures of my workspace. Filling it to the calibration mark was easy thanks to the clear marking on the neck. There were no issues with leaks or contamination thanks to the secure glass stopper.
Using the flask was intuitive. I didn’t need any special training or acclimatisation. The flask sat steady on the workbench, and the narrow neck facilitated easy and precise filling without spillage. No surprises, just reliable performance.
Extended Use & Reliability
After several months of regular use, the Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Class B, Kimble Chase 28015 10 is still performing admirably. There are no signs of clouding or etching on the glass despite repeated exposure to various chemicals. The stopper remains a snug fit.
The flask has proven remarkably durable. While I handle it with care, it has withstood a few accidental bumps without any damage. Cleaning is straightforward with standard laboratory detergents and a bottle brush. It continues to outperform the cheaper plastic flasks I initially used.
