Let’s Dive into Kimble/Kontes KIMAX Culture Tubes, Reusable, with Screw Cap, Kimble Chase 45066 25150 With Rubber-Lined Caps
The Kimble/Kontes KIMAX Culture Tubes are essential lab equipment for anyone involved in culturing, storing, or experimenting with biological materials. Manufactured by Kimble Chase, a trusted name in laboratory glassware, these tubes boast reusability and a screw cap design for secure containment. What sets them apart is the included rubber-lined cap, designed for creating a tight seal suitable for autoclaving and other sensitive procedures. These aren’t your average test tubes; they’re designed for precision and durability in the demanding world of scientific research.
My work in evaluating emergency sanitation protocols often involves collecting and storing samples in various environments. I needed a reliable, reusable container that could withstand harsh conditions and ensure sample integrity. Single-use plastic tubes contributed heavily to waste, and I needed a more sustainable solution.
My first impression upon unboxing a set of these tubes was positive. The glass felt substantial, and the screw caps seemed well-made and provided a tight fit. The rubber lining was clean and appeared to be of high quality.
I considered cheaper plastic alternatives and even some borosilicate tubes with snap caps. However, the Kimble/Kontes KIMAX Culture Tubes‘ reusability, combined with the reliable seal of the screw cap and rubber liner, ultimately swayed me. The ability to autoclave them for sterilization was the deciding factor, ensuring the integrity of my samples was maintained. I was pleasantly surprised by the overall build quality; the tubes felt robust and ready for fieldwork.
Real-World Testing: Putting Kimble/Kontes KIMAX Culture Tubes, Reusable, with Screw Cap, Kimble Chase 45066 25150 With Rubber-Lined Caps to the Test
First Use Experience
My initial field test involved collecting water samples from remote streams in the Pacific Northwest. The aim was to assess the presence of fecal coliform bacteria. The tubes were used to store the collected water samples, which were then transported back to the lab for analysis.
The varied weather conditions ranged from damp and cool to surprisingly sunny and warm. The tubes performed admirably; the caps remained secure, preventing any leaks or contamination, despite being jostled in my backpack. They were easy to handle, even with gloved hands, and the marking spot allowed for clear labeling with a permanent marker.
The tubes required no real acclimation period; they were ready to use right out of the box. The only initial concern I had was the potential for breakage during transport, which led me to ensure adequate padding in my pack. No issues were experienced during first use.
Extended Use & Reliability
After several months of regular use, these Kimble/Kontes KIMAX Culture Tubes have proven to be incredibly reliable. The glass is holding up well with no cracks or chips despite repeated autoclaving cycles and exposure to various cleaning solutions. The rubber liners are still intact and sealing tightly.
There are no noticeable signs of wear and tear on the glass itself. The rubber liners, however, will begin to show slight discoloration with repeated autoclaving, though this has not affected their sealing ability. Cleaning involves a simple wash with soap and water, followed by autoclaving for sterilization.
These tubes have significantly outperformed the plastic disposable tubes I used previously. The reusability alone has saved me money and reduced waste. The superior seal provided by the screw cap and rubber liner provides greater assurance of sample integrity.
