The borosilicate glass, known for its chemical resistance and durability, felt substantial in hand. The flip-top lid operated smoothly, hinting at the precision engineering within.
I considered similar weighing bottles from Corning and Wheaton, but the KIMAX bottles stood out due to their combination of features: the leveling base, the one-handed flip-top, and the inclusion of a SHOWIX glass weigher. The promise of long-life accuracy with the weigher sealed the deal, as consistent measurements are crucial for my analyses.
My first impression was one of quiet confidence. These weren’t flashy gadgets, but tools designed for serious work, promising accuracy and reliability in a field where precision is non-negotiable.
Real-World Testing: Putting Kimble/Kontes KIMAX Cylindrical Weighing Bottles, Regular and Tall Form, Kimble Chase 15146-4050 to the Test
First Use Experience
My initial testing involved analyzing the hydrophobic properties of various durable water repellent (DWR) coatings used on outdoor gear. This involved precise weighing of the DWR powder before and after application to fabric samples.
The Kimble/Kontes KIMAX Cylindrical Weighing Bottle’s spout design proved invaluable, allowing for controlled pouring without spills or waste, even in the somewhat cramped confines of my testing lab. The leveling base provided stability, preventing accidental tipping on uneven surfaces. I appreciated that immediately.
It took no time at all to integrate the bottles into my workflow. The smooth operation of the flip-top lid and the clarity of the glass made the weighing process efficient and error-free. The weigher proved accurate, providing consistent readings across multiple samples. There were no surprises, just reliable performance.
Extended Use & Reliability
After months of regular use, the Kimble/Kontes KIMAX Cylindrical Weighing Bottles have proven to be a dependable asset in my testing procedures. Despite being handled frequently, the borosilicate glass remains free from scratches or clouding.
The bottles have withstood accidental bumps and minor impacts without chipping or cracking, testament to the robust construction. Cleaning is a breeze; a simple rinse with distilled water and a wipe with a lint-free cloth keeps them pristine.
Compared to cheaper plastic vials I previously used, the KIMAX bottles offer vastly superior chemical resistance and dimensional stability. The plastic vials would sometimes react with certain solvents, skewing results and requiring frequent replacement. The KIMAX bottles have completely eliminated this issue.
