Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with ST PTFE Stopper, RAY-SORB, Class A, Kimble Chase 28016 25 to the Test
First Use Experience
My first test involved preparing a standard solution of a light-sensitive dye for spectrophotometric analysis. The testing occurred inside a controlled laboratory environment with calibrated equipment. The solution had to be precisely diluted to a specific concentration under ambient light conditions.
The Kimble/Kontes KIMAX flask performed flawlessly. The flask’s wide mouth and short neck allowed for easy and controlled filling of the liquid without spillage or bubbles. It was immediately clear that the PTFE stopper created an airtight seal preventing any evaporation during the solution preparation. There was no noticeable degradation of the light-sensitive dye, which was a big relief.
Extended Use & Reliability
After several weeks of consistent use, the Kimble/Kontes KIMAX flask continues to perform admirably. Its durability has been exceptional, with no signs of etching or cloudiness from repeated exposure to various chemicals. Cleaning is straightforward, thanks to the smooth glass surface and the chemical resistance of the PTFE stopper. This is a vast improvement compared to my previous experiences with cheaper flasks that degraded over time, affecting the accuracy of my measurements.
