Let’s Dive into Kimble/Kontes KIMAX Test Tubes, Reusable, Borosilicate Glass, Kimble Chase 45042 20150
The Kimble/Kontes KIMAX Test Tubes, Reusable, Borosilicate Glass, Kimble Chase 45042 20150 are laboratory staples, renowned for their durability and resistance to thermal shock. These aren’t your flimsy, disposable tubes; these are built for repeated use and designed to withstand rigorous conditions. Manufactured by Kimble Chase, a trusted name in labware, they represent a blend of quality and practicality.
My path to these particular test tubes started, perhaps unusually, in my workshop. I was seeking a robust, reusable container for mixing and storing small batches of custom lubricant blends for my firearms. The inconsistent quality of plastic containers led me down the borosilicate glass rabbit hole, and that’s where I discovered the Kimble/Kontes KIMAX Test Tubes.
Unboxing these felt less like receiving a product and more like acquiring a tool. The tubes themselves are substantial, with a reassuring weight that speaks to their borosilicate glass construction. The conical bottom and fluted ends are well-defined, and the included red plastisol lids fit snugly.
Initially, I considered cheaper alternatives made of thinner glass, but I’ve learned the hard way that cutting corners on quality often backfires. I opted for the KIMAX tubes because I wanted something that could handle temperature fluctuations and occasional accidental bumps without shattering. My past experience with Kimble labware gave me the confidence to spend more for better quality.
My first impression was one of quiet satisfaction. These weren’t flashy or exciting, but they felt solid, dependable, and perfectly suited for the task at hand. They weren’t just test tubes; they were miniature fortresses for my precious lubricants.
Real-World Testing: Putting Kimble/Kontes KIMAX Test Tubes, Reusable, Borosilicate Glass, Kimble Chase 45042 20150 to the Test
First Use Experience
My initial test involved mixing a batch of CLP (Cleaner, Lubricant, Protectant) for my AR-15. The KIMAX tube handled the solvents and oils with ease, showing no signs of degradation or leaching. The conical bottom proved useful for efficiently mixing small volumes.
I tested the tubes in both hot and cold environments. I placed one in a freezer overnight and another near a heat source, and neither cracked or showed any signs of stress. Cleaning was simple: hot water and dish soap were sufficient to remove all residue.
The only slight issue was the size; at 20 x 150 mm, it was a tad large for some of the smaller batches I wanted to mix. However, the added volume offered more headroom and reduced the risk of spillage. The larger size ultimately proved more versatile.
Extended Use & Reliability
After several months of regular use, the KIMAX tubes have proven incredibly durable. They’ve been dropped (accidentally, of course) onto my workbench without any cracks or chips. The red plastisol lids have also held up well, maintaining a tight seal.
I’ve even started using them for storing small quantities of gunpowder for reloading. The airtight seal of the lids and the chemically inert glass make them perfect for this purpose. The tubes have become indispensable in my workshop.
In contrast to my previous experiences with flimsy plastic containers, the KIMAX tubes have far exceeded my expectations. The Kimble Chase tubes consistently deliver reliable performance in challenging conditions. The difference in quality is undeniable.
