Real-World Testing: Putting Kimble/Kontes KIMAX Volumetric Flasks with ST PTFE Stopper, RAY-SORB, Class A, Kimble Chase 28016 250 to the Test
First Use Experience
I first used the Kimble/Kontes KIMAX Volumetric Flask in our lab to prepare a standard solution of Vitamin B12, known for its light sensitivity. The process involved dissolving a precise amount of the vitamin in a solvent and bringing it to the 250 mL mark on the flask. The white marking spot made it incredibly easy to label the flask clearly.
The PTFE stopper provided a secure seal, and I noticed the blue handle allowed for easy identification among other flasks. The lab environment is temperature-controlled, but indirect sunlight still penetrates, so the RAY-SORB feature was immediately put to the test. The flask was easy to handle, and I quickly achieved the desired volume with minimal fuss.
There were no immediate issues, but I was keen to monitor the solution’s stability over time, a crucial aspect given my initial concerns about light degradation. After the first use, I was pleased, but the true test would be its long-term performance.
Extended Use & Reliability
After several weeks of using the Kimble/Kontes KIMAX Volumetric Flask regularly, I’m happy to report it has consistently performed as expected. The Vitamin B12 standard solution remained stable, showing minimal signs of degradation compared to previous preparations in standard clear glass flasks. The RAY-SORB coating is clearly making a difference.
The flask has also proven to be surprisingly durable. Despite regular handling and washing, there are no visible scratches or signs of wear on the glass. Cleaning is straightforward; a simple wash with mild detergent and distilled water is sufficient.
Comparing it to my previous experiences with standard volumetric flasks, the Kimble/Kontes KIMAX flask has far exceeded my expectations. The accuracy is reliable, and the protection it provides to light-sensitive compounds is invaluable. It is a tangible upgrade in both quality and performance.
