Let’s Dive into Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 200
The Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 200 isn’t exactly your everyday tactical gear, but precision and accuracy are crucial in many field applications, from water purification to analyzing soil samples. Think of it as the sniper rifle of the chemistry world: meticulously engineered for repeatable, reliable performance. The Kimble Chase brand is synonymous with quality labware, promising accuracy and durability, and this specific flask, with its 200mL capacity and Class A certification, certainly piqued my interest.
My work often involves assessing water quality in remote areas. Ensuring correct dilution for reagents is paramount for accurate results. I was looking for a reliable, portable, and easily cleanable solution, better than the improvised methods I sometimes had to resort to in the field.
Upon unboxing the flask, the first thing that struck me was the quality of the glass. It’s noticeably thicker than standard lab glassware, imparting a sense of robustness. The PTFE stopper fits snugly, promising a tight seal, and the blue color-coding is a thoughtful touch for quick identification. It felt more serious than the plastic beakers I was used to.
Compared to graduated cylinders or generic flasks, the Kimble/Kontes KIMAX Volumetric Flask offers far superior accuracy for preparing solutions of known concentrations. While a plastic graduated cylinder might offer similar volume markings, the Class A certification of this flask guarantees a much tighter tolerance. This precision is essential when results matter.
Initially, I was excited but also a little apprehensive. Lab-grade glassware isn’t something you typically throw in a backpack, so I wondered about its real-world practicality. Could something so delicate actually be useful in harsh conditions?
Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 200 to the Test
First Use Experience
I tested the Kimble/Kontes KIMAX Volumetric Flask during a recent wilderness first aid course I was teaching. We were demonstrating water purification techniques and discussing the importance of precise chemical additions for disinfection. We needed to show exactly how much bleach to add to sanitize water and the flask allowed a clear precise measurement.
The conditions were relatively mild, but we were working outdoors with limited facilities. The flask proved surprisingly easy to use, even with slightly shaky hands and less-than-ideal lighting. The graduation ring on the neck was easy to read, and the PTFE stopper prevented any leaks, even when the flask was accidentally knocked over in the dirt.
One initial surprise was how quickly the flask came up to temperature. When filled with cold stream water, the glass cooled rapidly. I had to account for that in my readings.
Extended Use & Reliability
After several months of use, the Kimble/Kontes KIMAX Volumetric Flask is still in excellent condition. I’ve used it repeatedly in the field and in my makeshift home lab. There are no chips or cracks, despite a few close calls during transport.
The KIMAX glass is surprisingly resistant to staining. Even after prolonged exposure to iodine solutions, a quick wash with soap and water is enough to restore it to its original clarity. The PTFE stopper has also held up well, showing no signs of degradation or loss of sealing ability.
Compared to the plastic beakers I previously relied on, the Kimble/Kontes KIMAX Volumetric Flask is a significant upgrade. It delivers far greater accuracy, is easier to clean, and inspires much more confidence in the results. It outperforms in every meaningful way.
Breaking Down the Features of Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 200
Specifications
Capacity: 200 mL. This is a useful size for a variety of applications, from preparing standard solutions to measuring out precise volumes of liquids.
Tolerance: ± 0.10 mL. The Class A certification guarantees that the actual volume is within 0.10 mL of the marked volume. This is crucial for accurate quantitative analysis.
ST Stopper Size: 16. The standard taper stopper ensures a secure and leak-proof seal, minimizing evaporation and contamination.
Stopper Handle Color: Blue. The color-coded handle allows for quick and easy identification, especially when working with multiple flasks containing different solutions.
Kimble Chase No.: 28014F 200. This is the specific product code for easy reordering and identification.
Material: KIMAX borosilicate glass. This glass offers excellent chemical resistance and thermal stability, making it suitable for a wide range of applications.
These specifications are important because they directly impact the accuracy and reliability of any measurements made using the flask. The Class A certification, in particular, provides assurance that the flask meets strict standards for volumetric accuracy.
Performance & Functionality
The Kimble/Kontes KIMAX Volumetric Flask excels at its primary function: accurately measuring and containing liquids. The narrow neck and graduation ring allow for precise meniscus readings. The PTFE stopper prevents leaks and evaporation.
The main strength is its accuracy, but the chemical resistance of the glass is also a significant advantage. A slight weakness is its fragility.
It significantly exceeds my expectations for field use, given its lab-grade design. It brings a level of accuracy to on-site analysis that I previously thought was only possible in a controlled lab environment.
Design & Ergonomics
The build quality is exceptional. The KIMAX glass is clear, uniform, and free of imperfections. The flask feels solid and well-balanced in the hand.
It is user-friendly. The narrow neck makes it easy to fill without spillage. The color-coded stopper is a thoughtful ergonomic touch.
Durability & Maintenance
With careful handling, the Kimble/Kontes KIMAX Volumetric Flask should last for many years. The KIMAX glass is resistant to chemical attack and thermal shock.
Cleaning is simple. A quick wash with soap and water is usually sufficient. For more stubborn residues, a mild acid solution can be used.
Accessories and Customization Options
The flask comes standard with the PTFE stopper. There aren’t many customization options for a volumetric flask.
While not strictly accessories, consider purchasing additional stoppers of different colors for improved organization. Carrying cases or protective sleeves could also be useful for field transport.
