Real-World Testing: Putting Kimble/Kontes Natelson Capillary Tubes, Kimble Chase 604 Plain, Blue Color Code to the Test
First Use Experience
My first field test of the Kimble/Kontes Natelson Capillary Tubes was during a water quality assessment project in a remote mountain stream. The specific task involved collecting precise volumes of water for heavy metal analysis using a portable spectrophotometer. The tubes allowed for accurate and controlled sampling, eliminating spillage and ensuring consistent sample volumes, even with gloved hands.
The tubes performed flawlessly in the cool, damp environment. The smooth bore facilitated easy filling and dispensing, crucial when working with potentially contaminated water sources. I was surprised by how easily the fluid wicked into the tube due to the manufacturing process eliminating surface imperfections, making the process both faster and more accurate.
Extended Use & Reliability
After several months of consistent use in various field conditions (including hot desert environments and humid coastal regions), the Kimble/Kontes Natelson Capillary Tubes have proven remarkably durable. Despite being glass, they have withstood accidental bumps and jostling within my field kit without breaking – a testament to the quality of the glass and the careful packaging. Routine cleaning with laboratory-grade detergent has been straightforward, maintaining the integrity of the glass surface and ensuring accurate readings over time.
Compared to my previous experience with generic capillary tubes that would often clog or develop micro-cracks, these Kimble Chase tubes have significantly outperformed them in terms of reliability and longevity. They represent a tangible improvement in the consistency and accuracy of my field testing procedures, solidifying my confidence in their value.
