Let’s Dive into Kimble/Kontes KIMAX Volumetric Flasks with ST PTFE Stopper, RAY-SORB, Class A, Kimble Chase 28016 50
The Kimble/Kontes KIMAX Volumetric Flask with ST PTFE Stopper, RAY-SORB, Class A, Kimble Chase 28016 50 is not your everyday tactical gear item. Instead, it’s a specialized piece of laboratory equipment designed for precise measurements and protection of light-sensitive substances. Kimble Chase, a reputable manufacturer of scientific glassware, brings together accuracy and durability in this 50mL flask.
My work often involves assessing the purity and potency of field-collected samples, particularly when evaluating the effectiveness of water purification systems and improvised medicines. Accurate measurement is paramount in these situations, where even slight variations can drastically alter results. I needed a reliable, light-protected vessel for preparing standard solutions in challenging environments. This flask promised the accuracy and protection I required.
Unboxing this flask, I was immediately struck by the quality of the glass. The KIMAX borosilicate glass felt thick and robust, suggesting excellent resistance to thermal shock. The PTFE stopper fit snugly, ensuring a leak-proof seal, and the black handle was a thoughtful touch, adding to its usability. I was cautiously optimistic.
Compared to standard, non-RAY-SORB volumetric flasks, the slightly amber tint of the KIMAX glass was noticeable, indicating its light-filtering properties. I’ve used cheaper, generic flasks before, and their lack of precision and vulnerability to breakage always led to frustration. This Kimble/Kontes flask seemed like a worthwhile upgrade, especially considering the price difference.
My first impression was one of cautious excitement. The build quality and thoughtful design elements hinted at a high-performing and reliable tool. The high price tag still made me slightly anxious, as I’d need to prove it’s worth every penny.
Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with ST PTFE Stopper, RAY-SORB, Class A, Kimble Chase 28016 50 to the Test
First Use Experience
I tested the Kimble/Kontes KIMAX Volumetric Flask in a remote field lab setup while assessing the efficacy of UV disinfection methods on river water. The experiment involved preparing a specific concentration of a fluorescent tracer dye, which is sensitive to light degradation. This required precise volumetric measurement under less-than-ideal conditions, including varying temperatures and exposure to indirect sunlight.
The flask performed admirably, allowing for accurate dilution despite fluctuating ambient temperatures. The PTFE stopper sealed perfectly, preventing any spillage during mixing, even when I was forced to vigorously swirl the flask to dissolve the dye completely. There were no surprises, and it was surprisingly easy to use in a slightly chaotic field environment.
Extended Use & Reliability
After several weeks of regular use in the field and back at my permanent lab, the Kimble/Kontes KIMAX Volumetric Flask has held up exceptionally well. I’ve used it to prepare solutions of varying pH levels and organic solvents without any degradation of the glass or the PTFE stopper. The flask still looks and performs like new.
The durability of the KIMAX glass is evident; despite a few accidental bumps and scrapes, there are no chips or cracks. Cleaning the flask is simple, even after working with sticky or staining substances; a quick rinse with distilled water and a mild detergent is usually sufficient. This flask is proving to be a significant improvement over my previous glassware.
