Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Mixing Bulb Style, Class A, Kimble Chase 28019 1000 to the Test
First Use Experience
I tested the Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Mixing Bulb Style, Class A, Kimble Chase 28019 1000 in my makeshift field lab, nestled along the banks of the Skagit River. The conditions were relatively mild, with a slight breeze and ambient temperature around 65°F, but humidity was high. I needed to prepare a standard solution for alkalinity testing of river water.
The flask was surprisingly easy to use, even in the somewhat awkward environment of a portable lab bench. The mixing bulb proved effective for dissolving the reagent powder thoroughly and the narrow neck made it simple to top-off right at the clearly-marked graduation line. I experienced no issues with leakage or instability.
One minor issue arose during the initial use: I realized the glass was prone to showing fingerprints and water spots, which required frequent wiping to maintain visibility. This is a minor quibble, however, as the flask performed its primary function admirably.
