Let’s Dive into Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500
The Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 isn’t your everyday piece of gear; it’s a precision instrument designed for the demanding world of laboratory science. Manufactured by Kimble/Kontes, a trusted name in lab equipment, this volumetric flask promises accuracy and reliability. Its Class A certification, vibrant red coloring, and 500mL capacity make it an intriguing subject for rigorous review, especially when considering its rather hefty price tag.
My introduction to the need for such a precisely calibrated flask came during my time consulting for a small-scale bio-diesel production facility. We were struggling with consistent batch results, and traced the issue back to inaccurate volume measurements of key ingredients. The promise of Class A accuracy in the Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 offered a potential solution to this problem.
Unboxing the flask, or rather, the case of six flasks, the initial impression was one of substantial quality. The glass felt thick and robust, a far cry from some of the cheaper, thinner glass flasks I’d encountered. The red coloring wasn’t just aesthetic; it provided excellent contrast against the liquid contents, enhancing visibility during measurements.
Compared to standard borosilicate glass beakers we were previously using (primarily for their graduated markings), the Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 offered a significant upgrade in precision. We’d also looked at other Class A volumetric flasks from different manufacturers, but chose this particular model due to Kimble/Kontes’s reputation for durability and the positive feedback regarding the clarity of their graduation markings. My initial impression was cautiously optimistic – excited by the potential for improved accuracy, but aware that true validation would come from rigorous testing.
Real-World Testing: Putting Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 to the Test
First Use Experience
My first use of the Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 was in the biodiesel lab, specifically for preparing a titrant solution for fatty acid analysis. This required highly accurate measurements of sodium hydroxide. The controlled lab environment was ideal for observing subtle details in the flask’s performance.
The flask performed flawlessly. The single graduation ring was incredibly sharp and easy to read, minimizing parallax error. No adjustments were needed after the initial setup.
There were no surprises or issues during this initial use, just a smooth, accurate transfer and dilution.
Extended Use & Reliability
After several weeks of consistent use in the lab, the Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 continues to perform reliably. We’ve used it for various applications including preparing standard solutions, calibrating instruments, and performing volumetric titrations. The accuracy has remained consistent throughout.
The flasks have shown no signs of wear and tear, even with frequent washing and exposure to various chemicals. The glass remains clear and the graduation mark is still sharp. Cleaning these flasks is remarkably easy due to the smooth, non-reactive surface of the borosilicate glass.
Compared to our previous experience with less precise glassware, the Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 has vastly improved the consistency and accuracy of our experiments, greatly reducing batch to batch variations. The improvements in our measurement accuracy have exceeded expectations, leading to more reliable biodiesel production.
Breaking Down the Features of Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500
Specifications
The Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 boasts several key specifications that define its performance. Its capacity is 500mL, calibrated to contain (TC) at a specific temperature (typically 20°C).
It carries a Class A certification, indicating a high level of accuracy with a tolerance of ±0.20mL. The flask features a standard taper stopper size of 9, ensuring a secure and leak-proof closure. Its approximate height with the stopper is 287mm.

The Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 performs its primary function – accurate volume measurement – exceptionally well. Its accuracy and ease of use make it a valuable tool for any laboratory setting.
One strength is the extremely clear and easy-to-read graduation mark, crucial for precise measurements. A potential weakness, though inherent to volumetric flasks, is the need for careful meniscus observation, requiring a trained eye to avoid errors. It meets and exceeds expectations for accuracy and consistency.
Design & Ergonomics
The flask’s design is simple and functional. The red coloring enhances visibility and prevents confusion with other clear glassware.
The flask’s weight is balanced, making it easy to handle. However, volumetric flasks, in general, can be somewhat fragile, requiring careful handling. The flask does not necessarily have ergonomic features but it is easy to work with once the user is familiar with volumetric flask use.
Durability & Maintenance
Made from high-quality borosilicate glass, the Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 is designed for longevity. With proper care, it should last for many years.
Cleaning is straightforward using standard laboratory detergents and brushes. Autoclaving is possible, but repeated autoclaving can eventually weaken the glass over time.
Accessories and Customization Options
The Kimble/Kontes Flask Vol Cls A Red 500ML 6CS 28014R500 comes with a standard taper glass stopper. While there are no specific customization options for the flask itself, the stopper can be replaced with alternative stoppers made of different materials, such as silicone or rubber, depending on the chemical compatibility requirements.
It is also fully compatible with a range of standard laboratory accessories, such as funnels, pipettes, and volumetric dispensers. No proprietary accessories are required.
