Let’s Dive into Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 10
The Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 10 represents a cornerstone of precise liquid measurement in laboratory settings. Manufactured by Kimble Chase, these flasks are designed for accuracy and reliability, featuring a Class A certification, indicating adherence to stringent quality standards. The color-coded PTFE stopper adds a layer of convenience and organization to the lab environment.
My journey to find this flask stemmed from a need for exceptionally accurate dilutions in the field. Specifically, I’ve been developing portable water testing kits for remote expeditions, where precise reagent preparation is absolutely critical for reliable results. The Kimble/Kontes name is synonymous with quality in labware, so it was a natural starting point.
Unboxing the flask, I was immediately struck by the clarity and uniform thickness of the glass. The KIMAX borosilicate glass inspires confidence in its chemical resistance and thermal stability, crucial for field applications where temperature fluctuations are inevitable. The PTFE stopper, snugly fitted and smoothly rotating, felt premium and promised excellent sealing.
Compared to cheaper, non-certified volumetric flasks I’ve used in the past, the difference is night and day. These lesser flasks often have noticeable imperfections in the graduation ring, leading to inaccuracies, and their stoppers tend to leak or become brittle over time. The Kimble/Kontes flask, while significantly pricier at $569.99, offers the peace of mind that comes with knowing you’re working with a precision instrument.
My initial impression was one of cautious excitement. The promise of Class A accuracy and the known durability of KIMAX glass were certainly appealing. The high price tag, however, meant that its performance would need to be exemplary to justify the investment.
Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 10 to the Test
First Use Experience
My first test involved preparing a standard solution for a nitrate assay while conducting water quality research near a remote alpine lake. The controlled lab setting mimicked the conditions I’d expect in a field lab environment. I found the flask easy to fill to the graduation mark, thanks to the clearly defined ring blasted onto the neck.
The flask performed flawlessly, even under the moderately challenging conditions of a makeshift field lab within my expedition vehicle. The PTFE stopper provided a tight seal, preventing any leakage during transport over bumpy terrain. No time was needed to get used to the flask, as its design is classical and intuitive.
No issues or surprises arose after the first use. The flask maintained its accuracy and integrity throughout the initial testing phase.
Extended Use & Reliability
After several months of repeated use in a variety of environmental conditions (from hot desert climates to freezing mountain environments), the Kimble/Kontes KIMAX Volumetric Flasks continues to perform consistently. There are no signs of degradation in glass clarity or volume marking precision.
The flask’s borosilicate glass exhibits no signs of etching or clouding after repeated exposure to various chemicals commonly used in water testing. Cleaning is also straightforward: a simple rinse with distilled water followed by air drying is sufficient to maintain its pristine condition. This level of ease of maintenance is critical in extended field deployments.
Compared to my previous experiences with cheaper labware, the Kimble/Kontes flask is a clear winner. Its consistent accuracy, chemical resistance, and overall durability far surpass those of its lower-cost counterparts.
