Field Test Review of the Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21
The Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21 is a seemingly simple piece of laboratory equipment, but its precision and reliability are paramount in numerous critical applications. Manufactured by Kimble/Kontes, a trusted name in scientific glassware, this 1-ounce (approximately 30ml) bottle features an AC (Acid-Cleaned) finish and a ground glass stopper, designed for secure and contamination-free storage of sensitive liquids. Its small size makes it ideal for handling small volumes of precious or hazardous materials, and its clear glass construction allows for easy visual inspection of the contents.
My journey to acquiring the Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21 began with a very specific need: storing ultra-pure solvents for cleaning optics in my precision rifle scopes. I needed something absolutely inert to prevent contamination, and a secure seal to avoid evaporation. I recall the frustration of previously using standard plastic bottles, only to find that they would leach contaminants into the solvents, leaving residue on my expensive glass.
Upon unboxing, my initial thought was of the quality of the glass itself. It felt substantial, not fragile, and the ground glass joint was impeccably finished. The bottle exudes a sense of precision, from the uniform wall thickness to the perfectly matched stopper. This contrasts starkly with some cheaper alternatives I’ve encountered with noticeable imperfections and ill-fitting closures.
Compared to standard lab bottles and repurposed containers, the Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21 stands out because of its certified acid-cleaned finish and ground glass joint. I specifically chose this bottle over cheaper options because the purity of my solvents is paramount. I have previously used standard, non-AC glass bottles and even high-quality HDPE containers, but they always introduced a subtle, oily residue to my cleaning process.
I was initially excited but also slightly apprehensive. While the Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21 promised uncompromising purity, its price tag, at $1119.00 for a case, is definitely a commitment. However, if it solved my contamination issues, the investment would be worthwhile.
Real-World Testing: Putting Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21 to the Test
First Use Experience
My first use of the Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21 was in my workshop, preparing a batch of isopropanol for lens cleaning. I carefully transferred the solvent into the bottle and immediately noticed the tight seal of the ground glass stopper. There was no noticeable odor or leakage, a stark contrast to previous containers.
I evaluated performance under varying conditions, from the controlled temperature of my workspace to the fluctuating humidity of my garage. Even in the humid garage, the stopper maintained a reliable seal, preventing evaporation and moisture ingress. The bottle was easy to handle, although I had to get used to gently twisting and seating the stopper to ensure a proper seal.
I experienced no issues with the bottle during first use, but was impressed by the superior seal. One minor surprise was how easily the glass became statically charged, attracting dust.

After several months of use, the Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21 has proven to be extremely reliable. The bottle shows no signs of wear and tear, even with frequent handling and cleaning. The glass remains crystal clear, and the ground glass joint continues to provide a secure seal.
The Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21 has proven durable, even after multiple cycles of cleaning with strong solvents. The glass appears resistant to etching or clouding, and the ground glass stopper still fits snugly. The only maintenance required is periodic cleaning with soap and water, followed by a rinse with distilled water to remove any residue.
Compared to my previous storage methods, the Kimble/Kontes Bottle Ac Grd Cl 1OZ CS432 5810133C 21 has been a significant improvement. My optics cleaning process is noticeably more effective, with fewer streaks and residue left behind. This has justified the initial expense and made me a believer in the importance of proper solvent storage.
