Real-World Testing: Putting Kimble/Kontes KIMAX Centrifuge Tubes, Graduated, Conical-Bottom, with Screw Caps, Kimble Chase 45166 15 Standard Tubes to the Test
First Use Experience
I first tested the Kimble/Kontes KIMAX Centrifuge Tubes with soil samples collected from a recent expedition in the Mojave Desert. The tubes were used to separate soil particles by density, utilizing a standard laboratory centrifuge. The samples varied in composition, ranging from fine silt to coarse sand.
The tubes performed admirably in the dry desert air, as well as the more humid conditions of my laboratory. I was specifically impressed with their ability to withstand high speeds without cracking or leaking. The screw caps provided a tight seal, preventing any sample loss during the centrifugation process.
Using the tubes was very straightforward. The graduated markings allowed for quick and easy measurements of the separated layers. No real learning curve was involved.
One minor issue I encountered was the labeling. While the ceramic marking spot is a nice feature, I wish it were slightly larger to accommodate more detailed information. However, this didn’t detract from the overall performance.
Extended Use & Reliability
After several months of consistent use, the Kimble/Kontes KIMAX Centrifuge Tubes have proven to be incredibly reliable. There are no signs of significant wear and tear. The graduations remain clear, and the caps still provide a secure seal.
The glass tubes are easy to clean with standard laboratory detergents and brushes. The conical bottom makes it easy to remove any remaining sediment. Regular cleaning prevents any cross-contamination between samples.
Compared to my previous experiences with plastic tubes, the Kimble/Kontes tubes are in a different league. They withstand repeated use and sterilization without any degradation in performance. They’ve significantly streamlined my workflow and increased my confidence in the accuracy of my results.
