Putting the Kimble/Kontes KIMAX Culture Tubes, Reusable, Borosilicate Glass, Kimble Chase 45048 20150 Through Its Paces
The Kimble/Kontes KIMAX Culture Tubes, Reusable, Borosilicate Glass, Kimble Chase 45048 20150 are laboratory staples, but their rugged borosilicate construction and heat-resistant design have potential for unexpected applications beyond the lab bench. While my primary experience lies in the unforgiving world of tactical and outdoor gear, the inherent properties of these tubes sparked my curiosity about their viability in field applications. I was particularly interested in assessing their durability and utility as improvised containers for sample collection and controlled heating/cooling scenarios in extreme environments.
Years of tracking samples in the field during expeditions and survival training exercises have highlighted the need for reliable, reusable containment. Standard plastic vials crack, melt, or leak under pressure, leaving precious samples vulnerable. I needed a solution that could withstand temperature fluctuations, rough handling, and the potential for chemical exposure – something more robust than flimsy plastic.
My initial impressions of the Kimble/Kontes tubes were positive; the thick glass felt substantial and well-made. I compared them to standard disposable plastic culture tubes and some lightweight aluminum vials I use for dry goods storage; the KIMAX tubes were noticeably heavier but promised far superior durability and chemical resistance. My initial excitement centered on the potential for these tubes to replace fragile plastic and unreliable metal containers in my field kit.
Real-World Testing: Putting Kimble/Kontes KIMAX Culture Tubes, Reusable, Borosilicate Glass, Kimble Chase 45048 20150 to the Test
First Use Experience
My first test involved using the Kimble/Kontes KIMAX Culture Tubes, Reusable, Borosilicate Glass, Kimble Chase 45048 20150 during a simulated wilderness survival scenario in the high desert of Arizona. I used them to collect soil samples for later analysis, to carry water purification tablets, and as makeshift measuring devices for mixing electrolyte solutions. The conical bottom made scooping samples easier than with flat-bottomed vials, and the wide mouth allowed for easy addition of tablets and powders.
The tubes performed admirably in the harsh, dry environment. Despite being jostled around in my pack and exposed to direct sunlight, they remained intact and leak-proof. The ease of cleaning, simply rinsing with water, was a significant advantage over plastic vials, which tend to retain odors and residue. There were no immediate issues, though I quickly realized the need for a secure carrying system to prevent breakage.
Extended Use & Reliability
After several weeks of using the Kimble/Kontes KIMAX Culture Tubes, Reusable, Borosilicate Glass, Kimble Chase 45048 20150 on various outdoor excursions, they have proven remarkably durable. While I haven’t subjected them to deliberate abuse, they have survived accidental drops onto hard surfaces (wrapped in cloth, of course) and prolonged exposure to temperature extremes. The glass remains clear, with no signs of etching or clouding from the various substances I’ve stored in them.
Maintaining the tubes is straightforward; a simple wash with soap and water is sufficient for most applications. Compared to my previous reliance on disposable plastic vials, the KIMAX tubes offer a far more reliable and environmentally friendly solution. They have outperformed expectations in terms of durability and reusability, though their weight and inherent fragility remain considerations for certain applications.
