Real-World Testing: Putting Kimble/Kontes KIMAX Centrifuge Tubes, Conical-Bottom, Graduated, Kimble Chase 45199 12 Heavy-Duty Tube to the Test
First Use Experience
I first deployed these tubes during a wilderness survival training exercise focused on water purification and sediment analysis. The location was a remote area in the Pacific Northwest, notorious for its unpredictable weather and rugged terrain. The Kimble/Kontes KIMAX Centrifuge Tubes were crucial for analyzing water samples from various sources for contaminants and particulate matter.
Despite the challenging conditions – rain, mud, and accidental drops – the tubes held up remarkably well. Their conical bottoms allowed for easy collection and separation of sediment. The graduated markings remained clear and legible even when wet or smudged, ensuring accurate measurements.
Using these tubes required no special skills. I had instant confidence using them. However, the first time, I was concerned about potential breakage, given the rocky terrain. That fear quickly dissipated after seeing the tube survive a drop from waist height onto a bed of small rocks with no visible damage.
Extended Use & Reliability
Over several months of use in both field and laboratory settings, the Kimble/Kontes KIMAX Centrifuge Tubes have proven their durability and reliability. I’ve subjected them to repeated cycles of centrifugation, heating, and cleaning, with no signs of degradation. They’ve become an indispensable tool.
The glass construction is exceptionally resistant to scratches and chemical etching, maintaining its clarity and accuracy over time. Cleaning is straightforward. I use standard laboratory detergents and brushes. Even after repeated sterilization cycles in an autoclave, the tubes show no signs of clouding or weakening.
Previously, I relied on plastic tubes that often cracked or warped after a few uses. The Kimble/Kontes KIMAX Centrifuge Tubes have significantly outperformed those alternatives, offering a level of durability and consistency that I’ve come to rely on for precision work. This has drastically reduced waste and saved valuable time.
