All About the Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Class B, Kimble Chase 28015 50: Start Here
The Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Class B, Kimble Chase 28015 50 might seem like an odd item for an outdoor and tactical gear specialist to review. However, precision and accuracy are vital in many outdoor skills, from mixing precise ratios of fuel for a backpacking stove to carefully measuring water purification solutions in a survival situation. The Kimble/Kontes brand is synonymous with laboratory-grade quality, and the promise of accurate measurement in a compact 50mL flask piqued my interest.
I needed a reliable way to measure small quantities of liquids accurately for tasks like diluting concentrated insecticides for tick control in base camp, or creating small batches of specialized lubricant for firearm maintenance in the field. Many consumer-grade measuring devices lack the precision and durability required for demanding outdoor environments. This flask seemed to offer a solution, combining laboratory accuracy with the resilience needed for outdoor use.
Upon unboxing, the first thing that struck me was the heft and clarity of the glass. It’s immediately apparent that this isn’t your average graduated cylinder from a high school chemistry set. The ground glass stopper fit snugly and securely, promising a leak-proof seal.
I considered alternatives like plastic graduated cylinders or even syringes. However, plastic can degrade over time with exposure to chemicals and temperature fluctuations, impacting accuracy. Syringes, while accurate for dispensing, aren’t ideal for mixing. The Kimble/Kontes flask, with its Class B calibration and glass construction, seemed like the most durable and accurate option for my needs.
My initial impression was one of cautious optimism. While the price of $539.99 for what is essentially a small glass bottle seems exorbitant, the promise of unmatched precision and durability makes me hopeful that it could be a worthwhile investment for specific applications.
Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Class B, Kimble Chase 28015 50 to the Test
First Use Experience
My first test involved measuring out precise amounts of a concentrated mosquito repellent for dilution in a larger batch of water. I performed this test in a controlled environment at my workshop, which mimics a field camp setting. The flask’s wide mouth made filling easy, and the graduation ring on the neck was remarkably clear and easy to read, even under dim lighting.
The ground glass stopper proved its worth immediately, creating a tight seal that prevented any leaks during mixing. I even intentionally jostled the flask to simulate the bumps and vibrations it might experience in a backpack, and it remained completely sealed. There were no surprises during initial use; the flask performed exactly as expected.
Extended Use & Reliability
After several weeks of use, primarily for mixing various lubricants and cleaning solutions for my firearms, the Kimble/Kontes KIMAX Volumetric Flask has held up remarkably well. There are no signs of etching or staining from the chemicals I’ve used, and the graduation ring remains as clear and legible as when it was new. Cleaning is relatively simple with warm soapy water and a bottle brush.
Compared to my previous reliance on cheaper plastic measuring cups, the Kimble/Kontes flask offers a significant improvement in accuracy and peace of mind. Knowing that my measurements are precise allows me to confidently create consistent batches of whatever solution I need. The only minor drawback is the fragility of glass; extra care is required when handling it in the field to avoid breakage.
Breaking Down the Features of Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Class B, Kimble Chase 28015 50
Specifications
The Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Class B, Kimble Chase 28015 50 boasts several key specifications:
- Capacity: 50 mL – This is perfect for small-batch mixing and dilution where precision is paramount.
- Tolerance: ±0.10 mL – This is the critical spec. It signifies the accuracy of the flask, indicating that measurements will be within 0.10 mL of the indicated volume, essential for laboratory-grade work.
- ST Stop. No.: 9 – This refers to the size and type of the ground glass stopper, ensuring a tight and standardized fit.
- Kimble Chase No.: 28015 50 – This is the manufacturer’s unique product identifier.
These specifications matter because they directly translate to the accuracy and reliability of the flask. The Tolerance specification, in particular, is crucial for applications where precise measurements are essential. A wider tolerance would render the flask unsuitable for tasks requiring a high degree of accuracy.
Performance & Functionality
The Kimble/Kontes KIMAX Volumetric Flask excels at its primary function: accurately measuring and containing liquids. The flask is calibrated to contain (TC), meaning it’s designed to hold exactly 50mL when filled to the graduation ring. Its tight-fitting glass stopper eliminates the risk of leaks and evaporation, preserving the integrity of the solution.
The primary strength of this flask is its accuracy, thanks to its Class B calibration. A potential weakness, common to all glassware, is its susceptibility to breakage. It meets my expectations for accuracy and usability, but requires careful handling.
Design & Ergonomics
The flask’s design is simple but effective. The narrow neck with the etched graduation ring allows for precise volume adjustments. The ground glass stopper provides a secure and leak-proof seal.
The flask is easy to hold and manipulate, although its glass construction means it’s more prone to slipping than plastic alternatives. There’s no real learning curve; it’s a straightforward measuring device.
Durability & Maintenance
Made from high-quality KIMAX borosilicate glass, the flask is resistant to chemical attack and thermal shock. This suggests it will last a long time with proper care.
Maintenance is simple: wash with mild detergent and water, and avoid abrasive cleaners that could scratch the glass. The flask is designed to withstand repeated use under normal laboratory conditions.
Accessories and Customization Options
The flask comes with a ground glass stopper. There are no other accessories or customization options available for this basic piece of laboratory equipment. However, Kimble/Kontes offers a variety of other sizes and types of volumetric flasks to suit different needs. Compatibility with accessories from other brands is not relevant in this case.
