Real-World Testing: Putting Kimble/Kontes KIMAX Brand Volumetric Flasks with Snap Cap, Class A 28008 10, Case of 12 to the Test
First Use Experience
I tested the Kimble/Kontes KIMAX Brand Volumetric Flasks in my laboratory setting, preparing standard solutions for chemical analysis. I needed to make a 10 ppm standard of a pesticide for GC/MS analysis. The lab environment presents challenges of ambient temperature fluctuations and potential for accidental spills.
The flasks performed admirably, especially when working with volatile solvents. The snap caps sealed well, minimizing evaporation. I immediately appreciated the narrow neck, which facilitated accurate filling to the meniscus.
There were no surprises, but I did notice how quickly the liquid leveled out to the calibration mark, thanks to the clean, uniform glass surface. This made achieving accurate volume readings a breeze.
Extended Use & Reliability
After several weeks of consistent use, the Kimble/Kontes KIMAX Brand Volumetric Flasks continue to hold up beautifully. There’s no noticeable degradation of the glass. Even after repeated washings and sterilization cycles, the calibration marks remain clear and legible.
The borosilicate glass construction is robust and resistant to typical lab chemicals and cleaning solutions. Maintenance is extremely simple. A quick wash with soap and water is usually sufficient.
Compared to past experiences with cheaper flasks that often developed hairline cracks or faded markings, the Kimble/Kontes flasks have proven significantly more reliable. They have given consistently more reproducible results. The flasks outperform my expectations by providing trustworthy, accurate, and dependable volumetric capabilities, saving me both time and resources.
