Let’s Dive into Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack
As a seasoned gear specialist, I’ve handled countless tools and equipment over the years. But there’s something uniquely satisfying about the precision and reliability of well-made lab equipment. Today, I’m diving deep into the Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack, a staple in any lab or field setting that demands accurate liquid measurement.
My work often requires me to measure and mix solutions in the field, from testing water samples to preparing controlled chemical mixtures for various applications. I needed a reliable and durable set of graduated cylinders with glass stoppers to ensure accuracy and prevent contamination. This pack, promising KIMAX quality and ASTM compliance, seemed like the perfect solution for my needs.
Upon unboxing, the cylinders felt substantial and well-made, crafted from what appeared to be sturdy borosilicate glass. The glass stoppers fit snugly, suggesting a tight seal to prevent evaporation or spillage. The white ceramic enamel scale looked clear and easy to read, promising accurate measurements in various lighting conditions.
Before settling on the Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack, I considered cheaper plastic alternatives and other glass cylinders without stoppers. The plastic options felt flimsy and prone to chemical degradation, while the open cylinders lacked the necessary protection against environmental contamination. The KIMAX cylinders offered a balance of durability, accuracy, and protection that the others couldn’t match.
My initial impression was one of cautious optimism. The build quality seemed excellent, but the true test would be in the field, under real-world conditions. Would these cylinders stand up to the rigors of constant use, temperature fluctuations, and the occasional accidental bump?

First Use Experience
My first field test involved measuring water samples in a remote wilderness area. I was analyzing the water quality of a stream, which involved mixing precise quantities of reagents for colorimetric tests. The KIMAX cylinder performed flawlessly.
The glass stopper ensured that my reagents stayed uncontaminated, even in the dusty environment. Pouring liquids into and out of the cylinder was easy, and the clear graduations allowed for accurate measurements, even in the dim light of the forest canopy.
Extended Use & Reliability
After several months of use, the Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack has proven its worth. The borosilicate glass shows no signs of clouding or etching, even after repeated exposure to harsh chemicals. The ceramic enamel scale remains clear and legible, resisting fading or chipping.
Cleaning the cylinders is straightforward, a quick rinse with soap and water is usually sufficient. Occasionally, I use a specialized lab cleaner to remove stubborn residues, but even then, the glass remains pristine. Compared to previous experiences with lower-quality cylinders, the KIMAX cylinders are a significant step up in terms of durability and reliability.
Breaking Down the Features of Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack
Specifications
The Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack boasts several key specifications. It features a capacity of 2000 mL, making it suitable for measuring larger volumes of liquids. The Graduation Range is from 100-2000 mL, offering a wide range of measurement capabilities.
The Graduation Interval is 20 mL, enabling relatively precise measurements. The Tolerance is ±10 mL, meaning that the actual volume may vary by up to 10 mL from the indicated value. The ST Stopper Size is 38, ensuring a secure fit to prevent spillage and contamination.
The Approximate Height is 550 mm, making it relatively tall and stable. The Kimble No. is 20039 2000, which is useful for reordering or referencing the product. The product is sold as a Pack, but the quantity per pack isn’t explicitly stated in the provided details.
These specifications are important because they determine the cylinder’s accuracy, range, and usability. The Class B designation indicates that the cylinder meets certain ASTM standards for accuracy, which is crucial for reliable measurements. The glass stopper ensures that the contents remain pure and uncontaminated, which is essential for sensitive chemical reactions and analyses.
Performance & Functionality
The Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack excels in its primary function: accurately measuring liquids. The clear graduations and stable base make it easy to pour liquids to the desired volume with minimal spillage. The glass stopper fits securely, preventing evaporation and contamination of the contents.
One potential weakness is the ±10 mL tolerance, which may be too high for applications requiring extreme precision. However, for most general laboratory and field applications, this level of accuracy is sufficient. Overall, the cylinder meets expectations and delivers reliable performance.
Design & Ergonomics
The KIMAX cylinder is designed with both functionality and ergonomics in mind. The borosilicate glass construction is robust and resistant to chemical attack. The tall, narrow shape provides stability and reduces the risk of tipping over.
The clear ceramic enamel scale is easy to read at a glance, even in low-light conditions. The glass stopper is easy to insert and remove, but provides a secure seal when in place. There is a slight learning curve associated with accurately reading the meniscus (the curved surface of the liquid), but this is common to all graduated cylinders.
Durability & Maintenance
The borosilicate glass construction ensures that the Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack is highly durable. With proper care, it should last for many years, even with frequent use. Cleaning is simple and straightforward, requiring only soap and water or a specialized lab cleaner.
Occasional sterilization may be necessary to remove any residual contaminants. The glass construction can withstand high temperatures, making it suitable for autoclaving or other sterilization methods.
Accessories and Customization Options
The Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack doesn’t come with many accessories, its simplicity being one of its strengths.
