Let’s Dive into Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 65
As a seasoned outdoor and tactical gear specialist, I’ve come across a plethora of tools and equipment designed for various purposes. However, some items, like the Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 65, might seem out of place in a typical outdoor/tactical setting. These funnels, manufactured by Kimble/Kontes, are designed for laboratory use, specifically for filtration and liquid transfer.
My interest in these funnels stemmed from a need for precise and durable equipment when preparing solutions for maintaining specialized gear and equipment. Many high-end optics, firearm components, and even some clothing items require very specific cleaning and maintenance solutions. Standard kitchen funnels simply don’t offer the chemical resistance or precision I need.
Upon unboxing, the first thing I noticed was the robust construction of the KIMAX glass. It felt significantly more durable than any consumer-grade glass funnel I’ve used. The walls were thick, the rim was smooth, and the long stem had a reassuring weight to it.
I considered several other lab-grade funnels, including some from Pyrex, but I chose the Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 65 because of its specific 58° angle. This angle, according to Kimble/Kontes, offers faster and more effective filtration, a critical factor when dealing with fine particulate matter in solutions.
My initial impression was one of cautious optimism. While I wasn’t exactly excited about a funnel, the build quality and the promise of superior filtration did pique my interest. The price of $299.99 seemed steep, but I was hopeful that its performance would justify the investment.
Real-World Testing: Putting Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 65 to the Test
First Use Experience
I first tested the Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 65 in my workshop while preparing a CLP (cleaner, lubricant, protectant) solution for my firearms. This process involved filtering the mixture through filter paper to remove any sediment. The funnel was placed in a flask, and I slowly poured the solution in.
The 58° angle did seem to facilitate faster filtration compared to the standard 60° funnels I’ve used in the past. There was less pooling of the solution on the filter paper. The fire-polished stem allowed for smooth and drip-free dispensing into the flask.
There wasn’t a significant learning curve; it’s a funnel, after all. However, I did appreciate the stability provided by the long stem, which prevented the funnel from tipping over easily. One initial surprise was the funnel’s capacity; the ConeVol., mL is only 60mL.
Extended Use & Reliability
After several weeks of using the Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 65 for various tasks, including preparing cleaning solutions for optics and waterproofing treatments for clothing, it has held up remarkably well. There are no signs of wear and tear on the glass. The KIMAX glass resists etching and staining from harsh chemicals, unlike plastic funnels.
Cleaning is a breeze; I simply rinse it with distilled water and allow it to air dry. Occasionally, I use a mild detergent to remove any stubborn residue. Compared to previous experiences with plastic funnels that would degrade over time, the Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 65 has significantly outperformed them in terms of durability and chemical resistance.
Breaking Down the Features of Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 65
