Real-World Testing: Putting Kimble/Kontes KIMAX Centrifuge Tubes with ST Glass Stopper, Conical-Bottom, Graduated, Kimble Chase 45153 50 to the Test
First Use Experience
I tested the Kimble/Kontes KIMAX Centrifuge Tubes in my lab, processing soil samples collected from a local training ground where various tactical gear is regularly tested. These samples were crucial for analyzing soil composition, particularly the presence of certain compounds leaching from the gear after exposure to the elements. I am using the tubes to separate the solids from the liquids in the soil samples.
The tubes performed flawlessly in the centrifugation process, even with demanding samples containing high levels of sediment. The conical bottom facilitated easy collection of the sediment, and the graduations allowed for precise measurement of the separated liquid. There were no issues.
Using these tubes was straightforward; the graduations were clear and easy to read, and the stopper created a reliable seal. I didn’t need any special training to get up to speed. The stopper, in particular, was a massive upgrade from using parafilm to seal my old plastic tubes.
The first time using them, I was particularly impressed by the clarity of the glass, which made it easy to observe the separation process. The tight seal of the stopper also prevented any leakage during centrifugation, a common problem with cheaper tubes.
Extended Use & Reliability
After several weeks of using the Kimble/Kontes KIMAX Centrifuge Tubes for various soil and water samples, they have consistently delivered reliable results. The graduations remain clear, and the stoppers continue to provide a secure seal, preventing contamination and evaporation. They are now my go-to tubes for all separation needs.
The tubes have shown no signs of wear and tear, despite repeated use and cleaning. The KIMAX glass is incredibly durable and resistant to scratching, ensuring the graduations remain legible over time. They are also chemically resistant to the various solvents and reagents I use in my lab.
Cleaning and maintaining the tubes is simple; they can be easily washed with soap and water or autoclaved for sterilization. The conical bottom design makes it easy to remove sediment and prevent buildup. This level of ease is critical when processing dozens of samples per day.
Compared to my previous experiences with cheaper plastic tubes, the Kimble/Kontes KIMAX tubes are a significant upgrade in terms of accuracy, reliability, and durability. The consistent performance and ease of use have made my sample preparation process more efficient and reduced the risk of errors.
