Let’s Dive into Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 1000
The Kimble/Kontes KIMAX Volumetric Flask with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 1000 is a crucial piece of lab equipment for anyone needing precise volume measurements. This flask isn’t just a container; it’s a cornerstone for accurate dilutions and standard solutions.
For years, I’ve struggled with inconsistent results when preparing solutions for field testing water samples. Getting repeatable, reliable results is essential, and my old, cracked flasks were simply not cutting it anymore. This led me to search for a Class A volumetric flask known for its accuracy, and the Kimble/Kontes name kept surfacing.
Upon receiving the flask, I was immediately struck by the clarity of the glass and the snug fit of the PTFE stopper. The flask felt substantial, reassuring me of its durability. The color-coded stopper was a smart addition, eliminating any confusion, particularly when working with multiple flasks simultaneously.
I considered cheaper alternatives, but the precision and reliability of KIMAX glassware outweighed the initial cost savings. Cheaper flasks often have wider tolerances, introducing errors that cascade through the entire experimental process. My first impression was one of relief; I felt confident that this flask would provide the consistent results I needed.
Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 1000 to the Test
First Use Experience
I tested the Kimble/Kontes KIMAX Volumetric Flask in my mobile lab, preparing calibration standards for a portable water quality meter. The flask needed to perform in a potentially bouncy environment as I drove between sample sites.
The PTFE stopper provided a leak-proof seal, even with jostling during transport. Filling the flask to the etched graduation mark was effortless thanks to the narrow neck, which minimized meniscus reading errors. The flask felt stable on the countertop, reducing the risk of accidental spills.
The only minor issue was the initial learning curve of perfectly seating the PTFE stopper. After a few tries, I developed a feel for the right amount of pressure to ensure a tight, leak-proof seal.
Extended Use & Reliability
After several weeks of regular use, the KIMAX flask is holding up exceptionally well. There are no signs of etching or cloudiness, even with repeated use of strong acids and bases.
Cleaning is simple; a quick rinse with distilled water is usually sufficient. Compared to my old flasks, which often required vigorous scrubbing to remove residue, the KIMAX flask remains pristine. I am more confident in the accuracy of my standards now, and the flask provides peace of mind that my results are based on precise measurements.
Breaking Down the Features of Kimble/Kontes KIMAX Volumetric Flasks with Color-Coded PTFE ST Stopper, Class A, Kimble Chase 28014F 1000

- Tolerance: ±0.30 mL. The Class A tolerance ensures highly accurate measurements, critical for quantitative analysis.
- ST Stopper Size: 22. This size provides a secure and standardized fit.
- Stopper Handle Color: Yellow. The color-coded stopper simplifies organization and reduces the risk of using the wrong stopper with a specific reagent.
- Kimble Chase No.: 28014F 1000. This identification number allows easy reordering and ensures consistent product quality.
- Material: KIMAX borosilicate glass. This glass type is known for its chemical resistance and low thermal expansion.
These specifications directly impact the reliability of my measurements. The tight tolerance means I can trust the volume, and the KIMAX glass ensures that the flask won’t react with or leach contaminants into my solutions.
Performance & Functionality
The Kimble/Kontes KIMAX Volumetric Flask excels in its primary function: delivering accurate volume measurements. The narrow neck of the flask makes it easy to fill precisely to the graduation mark.
The PTFE stopper provides a reliable seal, preventing evaporation and contamination. One minor weakness is the potential for air bubbles to become trapped near the graduation mark during filling. However, this is easily remedied by gently tapping the flask. Overall, the flask far exceeds my expectations.
Design & Ergonomics
The KIMAX flask has a classic, functional design. The weight feels balanced, and the flask sits securely on a flat surface.
While not flashy, the flask is clearly designed for ease of use, with a focus on accuracy. The narrow neck minimizes meniscus errors, and the color-coded stopper is a surprisingly useful feature. There’s no real learning curve; it’s intuitive to use from the start.
Durability & Maintenance
The KIMAX borosilicate glass is incredibly durable. I anticipate this flask lasting for many years with proper care.
Cleaning is a breeze; the smooth glass surface resists staining and is easily cleaned with standard lab detergents. I have accidentally bumped the flask a few times, and it has shown no signs of chipping or cracking.
Accessories and Customization Options
The Kimble/Kontes KIMAX Volumetric Flask is fairly straightforward, so accessory options are limited. However, a flask stand is a useful addition to prevent accidental tipping.
Other accessories could include specialized cleaning brushes. The flask is compatible with most standard lab equipment.
