Let Me Tell You About the Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack
The Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack represents a cornerstone of accurate liquid measurement in various professional settings. These cylinders, crafted by Kimble/Kontes, are designed for precision and durability.
My journey to acquiring this pack stemmed from a growing need for reliable volume measurement in wilderness survival skills training. I needed something more precise and consistent than improvised methods, especially when demonstrating water purification and solution preparation techniques.
Upon unboxing, the first thing that struck me was the sheer size and the robust feel of the borosilicate glass. The glass stoppers seated firmly, hinting at the airtight seal necessary for maintaining sample integrity.
I considered cheaper plastic cylinders, but the potential for leaching and inaccurate measurements steered me toward glass. I also looked at Class A cylinders, but for my purposes, the Class B accuracy of these Kimble/Kontes cylinders struck the right balance between precision and cost.
My initial reaction was one of cautious excitement. The quality seemed evident, but the true test would be how they performed in the field, under less-than-ideal conditions.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack to the Test
First Use Experience
My first field test took place during a wilderness first aid course I was teaching. We were demonstrating how to create oral rehydration solutions and precise medication dilutions, which require accurate measurements.
The Kimble/Kontes cylinders performed admirably, even with slightly turbid water sources. The white ceramic enamel scale was easy to read in varying light conditions, from bright sunlight to the dimness of the forest canopy.
The cylinders were easy to use right out of the box. However, I did immediately invest in a sturdy carrying case with individual compartments to protect them during transport.
One slight surprise was the size of the 2000 mL cylinder; it was larger than I initially envisioned, requiring a stable surface to prevent accidental tipping.
Extended Use & Reliability
After several months of regular use, primarily in outdoor educational settings, the Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders have held up remarkably well. Despite being glass, they’ve proven to be more resilient than I initially anticipated.
There are no visible signs of wear and tear, even with frequent cleaning and transport. However, I always handle them with care, treating them as the precision instruments they are.
Cleaning is straightforward; I use a mild detergent and a specialized bottle brush, followed by thorough rinsing with distilled water to avoid mineral deposits. Compared to using improvised measurement techniques or less accurate plastic alternatives, these cylinders have significantly improved the reliability and professionalism of my demonstrations.
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 features a single 2000 mL graduated cylinder. The capacity is 2000 mL, with a graduation range from 100-2000 mL.
The graduation interval is 20 mL, providing a reasonably fine level of detail for measurements. The tolerance is ±10 mL, typical for Class B cylinders.
The ST stopper size is 38, ensuring a snug fit and minimizing evaporation or contamination. The approximate height of the cylinder is 550 mm.
The cylinders and stoppers are crafted from durable borosilicate glass, known for its chemical resistance and thermal stability. The scale is made of durable white ceramic enamel, which resists fading and scratching.
These specifications matter because they directly impact the accuracy and reliability of measurements, especially when dealing with critical solutions or precise formulations. Borosilicate glass ensures chemical compatibility with a wide range of liquids, and the ceramic scale maintains legibility over time.
Performance & Functionality
The Kimble/Kontes KIMAX Graduated Cylinder performs its job exceptionally well, providing accurate and repeatable volume measurements. The 20 mL graduation interval is sufficient for most general applications.
A key strength is the chemical resistance of the borosilicate glass, allowing me to confidently measure various liquids without fear of contamination or degradation. A minor weakness is the relatively large tolerance (±10 mL), which might be a limitation for applications requiring extreme precision.
The cylinder meets and often exceeds my expectations for general laboratory and field use. However, for highly sensitive analytical work, a Class A cylinder might be preferable.
Design & Ergonomics
The build quality is excellent; the glass is thick and uniform, and the base provides good stability. The 2000mL cylinder is substantial, so it requires a stable surface to prevent tipping.
The design is user-friendly, with a clear and easy-to-read scale. There is virtually no learning curve; anyone familiar with basic lab equipment can use these cylinders effectively.
Durability & Maintenance
With proper care, these Kimble/Kontes cylinders should last for many years. Borosilicate glass is resistant to chemical attack and thermal shock, but it can still break if subjected to excessive force or sudden temperature changes.
Maintenance is straightforward. Regular cleaning with mild detergent and distilled water is typically sufficient.
Accessories and Customization Options
The Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 2000, Pack comes with a glass stopper. There are no other accessories or customization options directly associated with the cylinder itself, although replacement stoppers are available.
The cylinder is compatible with various laboratory stands and supports. I use a simple ring stand to provide additional stability in field settings.
