Real-World Testing: Putting Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Glass Stopper, Red Stripe, Class A 28013 200, Pack of 6 to the Test
First Use Experience
My initial testing involved preparing calibration standards for water quality analysis at a remote field site near the Colorado River. The flasks were used to dilute concentrated solutions to precise concentrations needed for calibrating our field instruments. The red stripe on the neck made it easy to accurately read the meniscus, even under variable lighting conditions.
In the windy, dusty environment, the secure glass stoppers proved invaluable, preventing contamination of the standards. The flasks were relatively easy to handle, although care was taken to prevent breakage on the uneven terrain. No issues arose during their first use.
The flasks require careful handling due to their glass construction. However, the clear markings and reliable stoppers quickly became second nature to use. The process was much faster and more precise than using less accurate graduated cylinders.
Extended Use & Reliability
After several weeks of continuous use in various field locations, the Kimble/Kontes KIMAX Brand Volumetric Flasks have proven to be remarkably durable. Minor scratches have appeared on the glass, which is inevitable, but they do not affect functionality. The stoppers continue to provide a tight seal.
Despite being transported in rugged conditions within a protective case, no chips or cracks have developed. Cleaning requires careful attention to avoid scratching the glass, but it is generally a straightforward process with appropriate laboratory detergents. Compared to plastic alternatives, these flasks provide more consistent measurements over time.
The clear advantages in accuracy and resistance to chemical degradation far outweigh the slightly more delicate nature of glass. The Kimble/Kontes KIMAX Brand Volumetric Flasks have become an essential part of my field testing kit. Their reliability ensures that the data I collect is dependable.
