Let’s Dive into Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 1000, Pack
The Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 1000, Pack represents a cornerstone in any laboratory or field testing environment demanding precise liquid measurement. Manufactured by Kimble/Kontes, a name synonymous with quality glassware, this pack promises accuracy, durability, and ease of use, making it an essential tool for a wide range of applications. From scientific research to industrial quality control, these cylinders offer a reliable solution for dispensing and measuring liquids with confidence.
My path to the Kimble/Kontes cylinder pack started with a growing frustration in my own field testing of water samples. I needed something more precise and reliable than the plastic graduated cylinders I’d been using, especially when dealing with temperature-sensitive solutions in varying environments.
Upon unboxing, the first thing that struck me was the robust feel of the borosilicate glass. The cylinders felt substantial, not fragile, and the glass stoppers fit snugly, hinting at their ability to prevent contamination and evaporation. The white ceramic enamel scale looked crisp and easy to read, a critical factor in field conditions where lighting can be less than ideal.
Compared to other Class B cylinders I’ve used, like those from Pyrex, the Kimble/Kontes cylinders felt more refined, especially in the stopper design. While the accuracy specifications were similar, the Kimble/Kontes cylinders seemed to prioritize user experience and long-term durability.
My initial impression was one of cautious optimism. I was excited to use a tool that felt purpose-built for the demanding conditions of field testing, but also mindful of the fragility of glass in a rugged environment.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 1000, Pack to the Test
First Use Experience
My first field test with the Kimble/Kontes cylinders was during a water quality assessment along a remote river system. I was testing pH levels and dissolved solids, requiring accurate measurements of various reagents. The cylinders proved invaluable in quickly and accurately measuring sample sizes.
Despite working in damp conditions with occasional splashes, the cylinders remained easy to grip and manipulate, even with gloves. The wide base and relatively short height of the 10mL and 25mL cylinders (as mentioned in the product description for other volumes) contributed to enhanced stability, reducing the risk of accidental spills on uneven terrain.
The clear graduation markings made reading volumes straightforward, even in dim light conditions. No special accommodations were needed; the marked increments were easy to discern and therefore easy to use right out of the box.
One minor issue arose when a stopper slipped from my grasp and rolled towards the river. Thankfully, I snagged it before it went for a swim, but it served as a reminder to handle the glass components with care.
Extended Use & Reliability
After several months of regular use, the Kimble/Kontes cylinders have held up remarkably well. Despite being transported in a padded case, I was initially concerned about their fragility, but the borosilicate glass has proven resilient to the bumps and jostles of field work.
I’ve noticed no significant signs of wear and tear beyond minor scratches on the glass surface. The ceramic enamel scale remains as clear and legible as it was on day one.
Cleaning is straightforward, requiring only soap and water, though I use a specialized glassware cleaning solution for more stubborn residues. The cylinders have maintained their clarity and accuracy.
In comparison to the cheaper plastic cylinders I previously used, the Kimble/Kontes cylinders offer significantly greater accuracy and reliability. The glass doesn’t degrade or react with chemicals, ensuring consistent and trustworthy results over time. The Kimble/Kontes cylinder offers a performance that more than satisfies the requirements of a high functioning and active laboratory.

Specifications
The Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 1000, Pack boasts several key specifications:
- Capacity: 1000 mL, providing a generous volume for various applications.
- Graduation Range: 50-1000 mL, allowing for measurements across a broad range of volumes.
- Graduation Interval: 10 mL, providing reasonable granularity for most measurement needs.
- Tolerance: ±5 mL, indicating the acceptable range of error in measurements, typical for Class B glassware.
- ST Stopper Size: 32, ensuring a secure and tight fit to prevent leakage and contamination.
- Approximate Height: 475 mm, a manageable size for benchtop use and storage.
- Material: Borosilicate Glass, known for its chemical resistance and thermal stability.
- ASTM Standards: Designed from ASTM Specification E1272, Style 2, Class B requirements and Stoppers are designed from ASTM Specification E675.
These specifications are crucial because they directly impact the accuracy and reliability of measurements. The borosilicate glass construction ensures that the cylinders can withstand a wide range of chemicals and temperatures without affecting the results. The Class B tolerance means it’s suitable for general laboratory use, though Class A cylinders offer tighter tolerances for more critical applications.
Performance & Functionality
The Kimble/Kontes KIMAX Brand Single Metric Scale Graduated Cylinders, Class B, with Glass Stoppers 20039 1000, Pack performs its job admirably, providing accurate and reliable liquid measurements. The clear graduation markings and stable base make it easy to use, even in demanding conditions.
Its strengths lie in its robust construction, chemical resistance, and ease of use. The glass stoppers provide a tight seal, preventing evaporation and contamination.
One potential weakness is the Class B tolerance. For applications requiring extremely precise measurements, Class A cylinders may be preferable. Overall, it meets and exceeds expectations for a Class B graduated cylinder.
Design & Ergonomics
The build quality is excellent, with thick, sturdy borosilicate glass providing a reassuring sense of durability. While glass is heavier than plastic, the weight feels balanced and manageable.
The cylinders are designed for ease of use, with a wide base for stability and clear, easy-to-read graduation markings. There is a slight learning curve in handling glass safely in a lab or field environment, but the design is intuitive and user-friendly.
Durability & Maintenance
Given the nature of borosilicate glass, with proper care, these cylinders should last for years. The glass is resistant to most chemicals and temperature changes, minimizing the risk of degradation.
Maintenance is simple, requiring only regular cleaning with soap and water or a specialized glassware cleaning solution. The sturdy construction minimizes the risk of accidental breakage.
