Kimble Chase provides these tubes for mycobacterial isolation and general culture work, promising durability and consistent performance.
My journey to these tubes began with a persistent issue in my DIY mushroom cultivation setup. I struggled with contamination and inconsistent media composition when using less-than-ideal containers. The promise of borosilicate glass and PTFE-lined caps offered a potential solution to maintaining a sterile and stable culture environment.
Upon unboxing, the Kimble/Kontes KIMAX Culture Tubes exuded quality. The glass felt substantial, and the caps screwed on smoothly and securely, giving a sense of airtightness. The brown base was a welcome addition, promising some degree of light protection for sensitive cultures.
Compared to generic test tubes and repurposed containers, the Kimble/Kontes KIMAX Culture Tubes were a clear upgrade. I had previously used disposable plastic tubes, but their lack of reusability and potential for leaching chemicals made them a less desirable long-term option. These KIMAX tubes felt purpose-built for the task.
My initial impression was one of excitement and cautious optimism. The price tag was a bit steep for a set of tubes, but the potential for reliable, reusable culture vessels seemed worth the investment. I was eager to put them to the test.

First Use Experience
My first use involved preparing and sterilizing potato dextrose agar (PDA) for mushroom cultivation. I poured the sterilized media into the Kimble/Kontes KIMAX Culture Tubes under a sterile flow hood. The wide mouth made pouring easy and minimized spills, a welcome change from my previous experiences.
The tubes performed flawlessly through multiple autoclave cycles. The PTFE-faced rubber-lined caps held their seal perfectly, preventing media evaporation or contamination during sterilization. I noticed no degradation of the glass or caps after repeated heating.
Extended Use & Reliability
After several weeks of use, the Kimble/Kontes KIMAX Culture Tubes have proven remarkably durable. I’ve dropped them (accidentally, of course!) on the countertop with no breakage, a testament to the KIMAX borosilicate glass.
Maintenance is straightforward: a simple wash with soap and water followed by autoclaving keeps them sterile. I’ve noticed no staining or residue buildup, even after culturing brightly colored fungi.
