What Happened When I Tried the Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250
The Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250 might not be the first piece of gear that springs to mind when thinking about outdoor or tactical applications. However, its robust construction and specific design features make it surprisingly versatile in certain situations, particularly within field research or remote laboratory setups. This flask, produced by Kimble/Kontes, known for their scientific glassware, boasts a narrow mouth and a 250ml capacity, constructed with an acid-etched mark on the neck and designed without a ground neck finish. I aim to explore its functionality beyond the lab, evaluating its practical use in scenarios where durability and controlled containment are paramount.
My journey with the Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250 began with a need for a highly durable and chemically resistant container for field testing water samples. Standard plastic bottles were proving unreliable, often cracking or leaching chemicals into the samples, thus compromising the results. The flask’s inert glass construction promised a solution to this problem, eliminating any potential contamination.
Upon unboxing, the flask felt significantly more robust than anticipated. The glass was noticeably thicker than typical laboratory glassware, inspiring confidence in its ability to withstand the rigors of field use. The acid-etched mark and lack of a ground neck finish were distinct features, clearly prioritizing chemical inertness over a perfectly sealed closure. This design choice, while initially concerning for spillage, highlighted the flask’s intended use in environments where stoppers or specialized closures were secondary.
Compared to typical lab beakers or consumer-grade flasks, the Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250 was chosen for its superior chemical resistance and manageable size. Plastic alternatives lacked the necessary inertness, while larger glass containers were too bulky for easy transport in the field. This specific Kimble/Kontes flask struck a balance between capacity, durability, and chemical compatibility.
My first impression was a mix of cautious optimism and intrigue. The flask’s build quality was immediately apparent, assuring me of its ability to endure demanding environments. However, I was slightly wary of the narrow mouth and lack of a tight seal, raising concerns about potential spillage during transport and the overall practicality in rugged outdoor settings.
Real-World Testing: Putting Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250 to the Test
First Use Experience
I first tested the Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250 during a week-long water quality assessment in a remote section of the Appalachian Trail. The flask served as a primary container for collecting and temporarily storing water samples from various streams and springs.

Cleaning the flask is straightforward; a simple rinse with soap and water is typically sufficient to remove any residue. Its inert glass construction also allows for sterilization with harsher chemicals without risk of degradation. In comparison to previous plastic containers, the Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250 has significantly outperformed them in terms of chemical resistance and long-term durability.
Breaking Down the Features of Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250
Specifications
The Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250 features a 250 ml capacity, ideal for moderate sample sizes. The flask is constructed from borosilicate glass, known for its superior chemical resistance and thermal stability. The narrow mouth design allows for controlled pouring and minimizes spillage.
The flask features a CS12 neck finish, which implies a specific neck size and shape compatible with certain stoppers and closures. There is an acid-etched mark on the neck, providing a permanent, chemically resistant labeling surface. Notably, the flask is supplied without a ground neck finish, suggesting it’s intended for applications where an airtight seal is not critical.
These specifications are important because they directly influence the flask’s suitability for specific tasks. The borosilicate glass ensures that the stored contents remain uncontaminated, crucial for scientific applications. The narrow mouth facilitates precise pouring, and the acid-etched mark allows for permanent sample identification.
Performance & Functionality
The Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250 excels in containing and protecting sensitive samples. Its chemical inertness is a key strength, preventing any leaching or reactions that could alter the composition of the stored substance. The narrow mouth design effectively reduces the risk of spillage during pouring and transfer, particularly in windy or unsteady conditions.
One weakness is the absence of a standardized stopper. While the CS12 neck finish suggests compatibility with specific stoppers, these are not included, and their availability may be limited. This forces users to source suitable closures independently, adding to the initial cost and setup time.
Overall, the Kimble/Kontes Flask Narrow Mouth 250ML CS12 26500B 250 meets its intended purpose admirably. The absence of a stopper is a minor inconvenience, but its superior chemical resistance and controlled pouring capabilities make it a valuable tool for specific applications.
