My background in outdoor and tactical gear may seem unrelated, but water quality is paramount in survival and preparedness scenarios. Knowing the exact levels of contaminants often dictates whether a water source is safe for consumption after treatment; therefore, I sought a professional tool for accurate water testing in the field. I needed a portable and reliable method to assess water quality beyond simple test strips.
Unboxing the tubes, I was immediately struck by the quality of the KIMAX glass. The tubes felt substantial and well-made, reassuring me of their durability for field use. The white ceramic enamel graduation lines were crisp and clear, suggesting meticulous manufacturing.
Initially, I considered cheaper, plastic alternatives from generic brands. However, the need for precise and repeatable results, especially in critical situations, led me to choose the Kimble/Kontes tubes. These color comparison tubes are constructed according to the APHA standard. I was impressed by the product’s attention to detail.
My first impression was one of cautious optimism. The Kimble/Kontes KIMAX Nessler Color Comparison Tubes, Tall Form, APHA Standard, Kimble Chase 45315-50100 appeared to be a professional-grade tool, but their practical utility in rugged, outdoor conditions remained to be seen. I was eager to put them to the test.
Real-World Testing: Putting Kimble/Kontes KIMAX Nessler Color Comparison Tubes, Tall Form, APHA Standard, Kimble Chase 45315-50100 to the Test
First Use Experience
My initial testing ground was a remote mountain stream during a week-long survival training exercise. I wanted to assess the tubes’ usability in a field setting and to compare their results with a portable digital water quality meter. I also tested samples from stagnant pools and natural springs in varying conditions.
The tubes performed admirably, even in the challenging environment. The tall form proved beneficial in minimizing parallax errors when making color comparisons, and the shadowless bottom provided uniform light transmission, facilitating consistent readings. The clear markings were helpful even in low-light conditions.
The tubes were easy to use, even with minimal training. The 50 and 100 mL graduations were straightforward, and the tall form made it easy to accurately fill the tubes. I followed APHA standard protocols for colorimetric testing.
One initial surprise was the fragility of the glass in a field setting. While the KIMAX glass is strong, a single drop onto rocks would likely shatter the tubes. Protective carrying cases are essential to mitigate damage.
Extended Use & Reliability
After several months of use across various outdoor environments, the Kimble/Kontes KIMAX Nessler Color Comparison Tubes, Tall Form, APHA Standard, Kimble Chase 45315-50100 have proven to be a reliable tool, assuming proper handling and protection. The graduation lines have remained clear and legible, resisting fading or wear. The tubes consistently provide accurate and repeatable results.
The tubes have shown no signs of degradation, despite exposure to varying temperatures and water conditions. The glass has resisted staining and chemical attack from various water samples. However, careful cleaning is essential to prevent cross-contamination between tests.
Maintenance is simple: thorough washing with laboratory-grade detergent and rinsing with distilled water after each use. Proper storage in a protective case prevents damage. The tubes outperform my expectations.
Comparing them to lower-quality plastic tubes, the Kimble/Kontes tubes offer significantly improved clarity, accuracy, and durability. They provide a level of confidence in water quality assessment that is simply unattainable with cheaper alternatives.
