My first impression was positive; these tubes appeared to be a robust and reliable solution for my sampling needs. For the hefty price, I was expecting just that.
Real-World Testing: Putting Kimble/Kontes KIMAX Culture Tubes, Reusable, with Screw Cap, Kimble Chase 45066A 20125 With PTFE-Faced Rubber-Lined Caps to the Test
First Use Experience
My first field test involved collecting water samples from a remote alpine stream known for its delicate ecosystem. The tubes were used to collect and transport samples for subsequent analysis of microbial communities and nutrient levels. The tubes held up admirably during the rough transport, nestled securely in my pack.
I experienced a range of conditions, from sunny, dry days to unexpected rain showers and even a brief hailstorm at higher elevations. The tubes proved to be completely leak-proof, even when subjected to rapid temperature changes. Getting a good grip with wet hands was never an issue.
The ease of use was notable; the wide mouth of the tube facilitated easy sample collection, and the screw caps tightened securely with minimal effort. No special tools or techniques were required, making them a convenient option for fieldwork. There were no initial issues or surprises; the tubes performed precisely as expected, providing a reliable vessel for my precious samples.
Extended Use & Reliability
After several months of regular use, the Kimble/Kontes tubes have proven to be exceptionally durable and reliable. There are no signs of etching or clouding, even after repeated exposure to various chemicals and repeated autoclaving. The glass remains crystal clear.
Despite being dropped on a few occasions (accidents happen!), the tubes have shown no signs of cracking or chipping, demonstrating the strength of the KIMAX glass. Cleaning and maintenance are straightforward; a simple wash with soap and water is usually sufficient, and the tubes can be easily sterilized in an autoclave for sensitive applications. I have come to expect that, and they don’t disappoint.
Compared to previous experiences with cheaper culture tubes, the Kimble/Kontes tubes have significantly outperformed them in terms of durability, chemical resistance, and sealing capability. They have exceeded my expectations. My previous test tubes warped during autoclaving and were disposed of due to sample contamination.
