Let’s Dive into Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Glass Stopper, Red Stripe, Class A 28013 500, Pack of 6
As an outdoor and tactical gear specialist, my expertise usually lies in evaluating knives, packs, and shelters. However, precise measurements and controlled environments are crucial in many field applications, like water purification or creating tinctures from foraged plants. The Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Glass Stopper, Red Stripe, Class A 28013 500, Pack of 6 offer a level of accuracy rarely found outside of a laboratory, promising consistent results and reliable measurements.
My interest in these flasks stemmed from a need for accurate liquid measurement in remote environments. I was experimenting with creating concentrated iodine solutions for water disinfection, and consistency was paramount. Prior to this, I relied on graduated cylinders and measuring cups, which never provided the pinpoint accuracy I desired.
The packaging was secure and well-protected, a testament to the fragility of the contents. Each flask, crafted from the renowned KIMAX glass, felt robust yet delicate, a paradox that inspires confidence. The glass stoppers fit snugly, promising an airtight seal essential for volatile solutions.
I considered cheaper, plastic alternatives, but the risk of chemical leaching and inaccurate measurements was unacceptable. I also looked at higher-end, individually serialized flasks, but the price point for my application was prohibitive. These Kimble/Kontes flasks struck a perfect balance between accuracy, durability, and affordability.
My initial reaction was a blend of excitement and respect. The flasks exuded a sense of precision and quality, promising a new level of accuracy in my outdoor applications. The red stripe and meticulously etched graduation line hinted at the care and attention to detail poured into their creation.
Real-World Testing: Putting Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Glass Stopper, Red Stripe, Class A 28013 500, Pack of 6 to the Test
First Use Experience
My first test involved creating a standardized solution of potassium permanganate for trailside wound care. I prepared the solution at my basecamp, using distilled water collected from a nearby spring. The precise volume control afforded by the flask ensured the correct concentration for effective antiseptic action.
While the flask’s primary function is lab-based, I found it surprisingly adaptable to outdoor use with a few modifications. I used a small, padded case to protect the flask during transport and stabilized it on a flat rock while filling. The clear markings and precise stopper allowed for easy and accurate solution preparation, even in slightly windy conditions.
It took a little practice to get used to filling the flask to the exact graduation line. The meniscus can be tricky to read at first, requiring careful eye-level observation. However, after a few uses, I became proficient in achieving the desired accuracy.
My initial worry was the glass construction, but the thick walls and sturdy base proved surprisingly resilient. The ST ground glass stopper created a tight seal, preventing any leakage or evaporation of the solution. The flasks stood up to the test of being used in a natural environment.
Extended Use & Reliability
After several weeks of use, the flasks have held up exceptionally well. The KIMAX glass remains crystal clear, resisting staining and etching even after repeated use with harsh chemicals. The red stripe and graduation line show no signs of fading or wear, maintaining their legibility.
The flasks have proven to be quite durable, surviving multiple trips in my pack with only minor scratches on the exterior. I am careful to protect them in a padded case, but they seem capable of withstanding reasonable handling. Regular cleaning with soap and water is sufficient to keep them in pristine condition.
Compared to my previous methods of using graduated cylinders, these flasks offer a significant improvement in accuracy and repeatability. The narrow neck and precise graduation line allow for far more accurate volume control, reducing the risk of errors in solution preparation. They have redefined the consistency I can achieve in field applications.
Breaking Down the Features of Kimble/Kontes KIMAX Brand Volumetric Flasks with ST Glass Stopper, Red Stripe, Class A 28013 500, Pack of 6
Specifications
The Kimble/Kontes KIMAX Brand Volumetric Flasks each have a Capacity of 500mL. The stated Tolerance (Tol.) is ±0.20mL, signifying a high degree of accuracy. They are equipped with an ST Stop.No. 19 ground glass stopper, ensuring a tight, leak-proof seal.
The Kimble* No. for this specific model is 28013 500, ensuring easy reordering and identification. This listing is for a Unit of a Pack of 6, making it cost-effective for multiple applications. The flasks are designed from ASTM Specification E288, Class A unserialized requirements, showcasing adherence to industry standards.
These specifications translate directly to the flask’s ability to deliver accurate and reliable measurements.
