Real-World Testing: Putting Kimble/Kontes Flask Vol Cls A Yel 100ML 6CS 28014Y100 to the Test
First Use Experience
My first use involved preparing a standard solution of sodium chloride for calibrating a conductivity meter. I needed a precise 100mL solution of known concentration for accurate meter calibration. I performed the experiment in a controlled laboratory environment at room temperature (22°C).
The flask was very easy to use; the wide mouth made it simple to add both solid solute and solvent without spillage. The graduation mark was clear and easy to read, minimizing parallax errors. I used a calibrated pipette to add the final few drops of water until the meniscus precisely met the etched line.
No issues arose during the initial use. The flask held the solution securely without any leaks from the stopper. I did appreciate the yellow color, as it stood out among the other clear glassware, minimizing potential for confusion.
Extended Use & Reliability
After several weeks of use, the Kimble/Kontes Flask Vol Cls A Yel 100ML 6CS 28014Y100 has consistently delivered accurate and reliable results. I have used it with a variety of aqueous solutions, including acids, bases, and organic solvents, without any signs of degradation or etching of the glass.
The flasks have proven durable and have withstood normal laboratory handling without chipping or cracking. I have dropped one accidentally from a height of about one foot onto a cushioned benchtop, and it survived unscathed. Proper cleaning is key to maintain its accuracy and prevent cross-contamination between solutions.
Cleaning is straightforward; I use a standard laboratory detergent and a soft brush, followed by thorough rinsing with distilled water. The glass cleans easily, and no residue remains after washing. Compared to cheaper, non-Class A flasks I have used previously, the Kimble/Kontes Flask Vol Cls A Yel 100ML 6CS 28014Y100 offers significantly greater peace of mind and delivers noticeably more consistent results.
