One Month Later: Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 2 Review

As an outdoor and tactical gear specialist, I’ve seen my fair share of precision instruments. But when it comes to accuracy and reliability in the field, laboratory-grade equipment often holds the key, especially when conducting water quality tests or analyzing soil samples. That’s why I was intrigued by the Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 2.

My need for this flask arose from a desire to conduct more precise and repeatable analyses of water samples collected from remote locations. I was tired of relying on less accurate methods, which often led to questionable data when assessing potential contamination. Upon unboxing the flask, the first thing I noticed was its robust construction and the well-fitting stopper. The Kimble/Kontes name inspires confidence, and the flask certainly looked and felt the part.

Compared to cheaper, non-Class A volumetric flasks I’ve used in the past, the Kimble/Kontes KIMAX flask was noticeably superior in terms of glass quality and stopper fit. Other flasks often have imperfect seals or inconsistent volume markings, and I chose this one because of its promise of Class A accuracy. My initial reaction was excitement; I was eager to put this piece of equipment to work and see if it would improve the precision of my field analyses.

Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 2 to the Test

First Use Experience

My first test involved analyzing water samples collected from a remote mountain stream, a location notorious for fluctuating mineral content. I used the Kimble/Kontes KIMAX Volumetric Flask to precisely dilute a sample for spectrophotometric analysis. The flask’s narrow neck and clear markings made it easy to achieve the desired volume with minimal error.

I conducted the test in moderately windy conditions with a slight drizzle; the secure PTFE stopper proved invaluable in preventing contamination from airborne particles and moisture. The ease of use was immediately apparent; filling the flask to the calibration mark was straightforward, and the stopper provided a leak-proof seal. One minor observation was that the test-tube shape of the 2mL flask required a bit more care when handling, as it was less stable than traditional flask shapes.

Extended Use & Reliability

After a month of regular use, the Kimble/Kontes KIMAX Volumetric Flask has held up remarkably well. Despite being transported in a rugged field kit, there are no signs of chipping or cracking in the glass. Cleaning is simple; the smooth glass surface and PTFE stopper are easy to rinse and dry, even with minimally treated water.

Compared to my previous experiences with less durable glassware, the Kimble/Kontes KIMAX flask has significantly exceeded my expectations in terms of both accuracy and robustness. It has become an indispensable part of my field testing kit, consistently delivering reliable results. I’m now more confident than ever in the precision of my water quality analyses.

Breaking Down the Features of Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 2

Specifications

• Capacity: 2 mL. This small capacity is ideal for situations where sample volume is limited.
• Tolerance: ±0.015 mL. The tight tolerance ensures high accuracy in measurements.
• ST Stopper Size: 8. This standard size is easy to handle and ensures a secure fit.
• Stopper Handle Color: Gray. The color-coded handle aids in quick identification.
• Kimble Chase No.: 28014F 2. This unique identifier helps in reordering and referencing the specific flask.
• Class A: Meeting Class A standards signifies high precision and adherence to strict manufacturing tolerances.
• Material: KIMAX borosilicate glass. Borosilicate glass is known for its chemical resistance and ability to withstand thermal shock.
• Stopper Material: PTFE (Polytetrafluoroethylene). PTFE is chemically inert and provides an excellent seal.

These specifications are crucial because they directly impact the reliability and accuracy of the flask’s measurements. The Class A certification, coupled with the tight tolerance, gives users confidence that the flask will deliver consistent and precise results. The borosilicate glass ensures that the flask is resistant to chemical reactions and can withstand temperature changes without compromising its accuracy.

Performance & Functionality

The Kimble/Kontes KIMAX Volumetric Flask excels in its primary function: providing precise volume measurements. The narrow neck of the flask allows for accurate filling to the calibration mark, and the PTFE stopper creates a tight seal, preventing leakage and contamination. It is important to note that its 2mL capacity makes it especially useful when only minute samples are available for testing.

The main strength lies in its accuracy and reliability; however, the small size can be a slight drawback in scenarios where larger volumes are required. This Kimble/Kontes flask meets and even exceeds expectations for a Class A volumetric flask, delivering consistently accurate results under various field conditions.

Design & Ergonomics

The flask is constructed from high-quality borosilicate glass, which feels robust and durable. Its test-tube shape, while unconventional for larger volumetric flasks, is appropriate for the 2mL capacity, making it easier to handle small volumes. The color-coded PTFE stopper is a practical touch, allowing for quick identification and easy removal, even with gloved hands.

The flask is relatively user-friendly, though the narrow neck requires a bit of care to avoid overfilling. There is no significant learning curve, but familiarity with standard laboratory practices is beneficial for maximizing its accuracy.

Durability & Maintenance

Given its borosilicate glass construction, the Kimble/Kontes KIMAX Volumetric Flask is expected to last for years with proper care. The glass is resistant to most chemicals and can withstand normal temperature fluctuations without damage. Maintenance is straightforward; rinsing with distilled water after each use is usually sufficient.

The PTFE stopper is also highly resistant to chemical degradation and can be easily cleaned. While the glass is durable, it is still susceptible to breakage if dropped or subjected to sudden impacts.

Accessories and Customization Options

The primary accessory included is the color-coded PTFE ST stopper, which is essential for maintaining the integrity of the sample. Given the specialized nature of volumetric flasks, there aren’t many traditional customization options. However, one could explore different stopper materials if specific chemical compatibility is needed.

The flask is compatible with standard laboratory equipment, such as micropipettes and titration setups, from various brands. While not a customization, proper storage solutions (such as racks designed for test tubes) are essential for ensuring the longevity of the flask.
