Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Polyethylene Stopper, Class A 28014P 100, Pack of 6 Review

The Good, the Bad & the Real of the Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Polyethylene Stopper, Class A 28014P 100, Pack of 6

The Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Polyethylene Stopper, Class A 28014P 100, Pack of 6 are laboratory essentials renowned for their precision and reliability in scientific measurements. Manufactured by Kimble/Kontes, a name synonymous with quality lab glassware, these flasks are calibrated to contain exactly 100mL of liquid at a specific temperature, ensuring accurate dilutions and solution preparations. This pack of six flasks is ideal for environments requiring consistent and precise volume measurements.

As a seasoned outdoor and tactical gear specialist, you might wonder why I’m reviewing volumetric flasks; it’s not as far-fetched as it seems. Precise measurements are crucial in many outdoor scenarios, from mixing chemical solutions for water purification to accurately diluting medications for first aid; these flasks could be adapted for field use where accuracy is paramount.

My journey to discovering the Kimble/Kontes flasks began with a need for precise volume control in a remote, off-grid homestead project. We needed to create solutions for sanitizing water and preserving food with pinpoint accuracy.

Upon unboxing, the immediate impression was one of quality and robustness. The KIMAX borosilicate glass felt substantial, and the polyethylene stoppers fitted snugly, promising secure closure. These stoppers have enlarged tops to protect the flask necks, which is great.

I initially considered cheaper, non-certified volumetric flasks, but I realized that even slight inaccuracies could have significant consequences in my applications. Ultimately, the Kimble/Kontes reputation for Class A accuracy and the pack of six offering swayed me. The precision and reliability offered by Kimble/Kontes far outweighed the initial cost difference.

My first impression was one of relief; I finally had tools I could trust for accurate solution preparation. I was excited to put them to the test in real-world scenarios, pushing them beyond the typical lab setting.

Real-World Testing: Putting Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Polyethylene Stopper, Class A 28014P 100, Pack of 6 to the Test

First Use Experience

My first test involved using the flasks to prepare a chlorine solution for disinfecting water sources during a backcountry camping trip. I needed to ensure the chlorine concentration was within a safe range to eliminate harmful bacteria and viruses, and the flasks allowed me to precisely dilute a concentrated bleach solution. The flasks, carefully packed, accompanied us on our journey.

The performance was impressive, even in the challenging outdoor environment, and the flasks held up well, and the polyethylene stoppers prevented any leaks, even with jostling. The clear graduation ring on the neck made it easy to accurately fill the flask to the 100mL mark, even in low light conditions. Initially, I was concerned about the fragility of glass in the wilderness, but careful handling and protective packing mitigated that risk.

The only real challenge was finding a perfectly level surface to ensure accurate filling, but with a bit of ingenuity, I managed to create a stable platform using rocks and a flat piece of wood.

Extended Use & Reliability

After several months of intermittent use, the Kimble/Kontes flasks have proven their durability and reliability. They’ve been used for everything from preparing fertilizer solutions for our garden to mixing precise ratios of epoxy resin for repairing outdoor gear. They get the job done, every time.

Despite being transported in backpacks and subjected to temperature fluctuations, none of the flasks have chipped or cracked, demonstrating the quality of the KIMAX borosilicate glass. Cleaning is relatively straightforward. Simply rinsing with soap and water has been sufficient to remove most residues.

Compared to my previous experiences with less precise measuring tools, the Kimble/Kontes flasks offer a significant improvement in accuracy and consistency. This has resulted in better yields in the garden, stronger repairs to gear, and greater peace of mind when treating water sources.

Specifications

The Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Polyethylene Stopper, Class A 28014P 100, Pack of 6 boasts several key specifications that contribute to its performance and reliability:

• Capacity: 100 mL. This is the volume the flask is calibrated to contain at a specific temperature.

• Tolerance: ±0.08 mL. This refers to the maximum allowable deviation from the stated capacity, ensuring high accuracy.

• Stopper Size: ST 13. This specifies the size of the standard taper (ST) ground neck and matching polyethylene stopper.

• Material: KIMAX Borosilicate Glass. Known for its excellent chemical resistance and thermal stability, this glass minimizes the risk of contamination and allows for use with a wide range of substances.

• Class A Certification. This indicates that the flasks meet stringent accuracy standards set by regulatory bodies.

• Pack of 6. This offers a convenient set for applications requiring multiple flasks or providing spares.

These specifications are crucial because they directly impact the accuracy and reliability of any solutions prepared using these flasks. The Class A certification and tight tolerance guarantee precise measurements. The borosilicate glass ensures that the flasks won’t react with the chemicals being measured, thus maintaining the integrity of the solution.
