Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 100 Review

The Road Test: Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 100

For years, I’ve relied on a hodgepodge of funnels – some inherited from my grandfather’s workshop, others cheap plastic models that cracked after minimal use. When I transitioned from field work to managing the supply chain for a disaster relief organization, I realized the absolute necessity of reliable, chemically resistant equipment. The Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 100 promised to be a solution, boasting chemical resistance and a design optimized for faster filtration.

My search began with a need: a durable, reliable funnel capable of transferring various liquids – from water purification solutions to fuel – in demanding field conditions. The inconsistent performance and fragility of my existing funnels were unacceptable, especially in situations where precision and speed were crucial.

The Kimble/Kontes funnel arrived well-packaged and immediately conveyed a sense of quality. The heavy, uniform glass and the smoothly fire-polished stem were noticeable improvements over my existing plastic funnels. It felt like a serious piece of equipment, designed for professional use.

I considered other options, like the Bel-Art Scienceware filtering funnel and various stainless steel funnels. Ultimately, the Kimble/Kontes funnel won out due to its specific focus on chemical resistance, the optimized 58° angle for faster filtration, and Kimble Chase’s reputation for producing reliable laboratory equipment. I was also hoping the glass construction would be easier to clean than some of the cheaper plastic options.

My first impression was one of cautious optimism. The price point felt high for a funnel, but the promise of durability and performance in harsh conditions justified the investment. I was eager to put it through its paces and see if it lived up to the Kimble Chase name.

Real-World Testing: Putting Kimble/Kontes KIMAX Filling Funnels, Long Stem, 58 Angle, Kimble Chase 28900 100 to the Test

First Use Experience

My initial testing ground was at our disaster relief staging area, simulating a scenario where we needed to quickly transfer water purification chemicals into smaller containers. The Kimble/Kontes KIMAX Filling Funnel handled sodium hypochlorite solutions and concentrated citric acid without any signs of degradation. The 58° angle did seem to facilitate a faster flow rate compared to a standard 60° funnel I had on hand.

The funnel was also tested during a training exercise where we practiced transferring fuel into portable generators. Even with the slightly viscous fuel, the flow remained consistent and relatively quick, minimizing spillage and wasted time. The long stem proved particularly useful in reaching the bottom of the generator’s fuel tank without making a mess.

The funnel was easy to use right out of the box; no special training was required. The strong, molded rim provided a secure grip, even with gloved hands. My only initial concern was the fragility of the glass in a rough handling environment, a concern that I addressed by using a funnel holder.

Extended Use & Reliability

After several months of consistent use in various scenarios, the Kimble/Kontes KIMAX Filling Funnel has proven to be a remarkably durable and reliable tool. Despite being made of glass, it hasn’t chipped or cracked, even after being subjected to occasional bumps and jostles during transport. The chemical resistance has also held up; there are no signs of staining or degradation from any of the solutions it’s handled.

Cleaning the funnel is incredibly easy. The smooth glass surface rinses clean with minimal effort, and any stubborn residue can be quickly removed with a laboratory detergent. The fire-polished stem prevents any material from clinging to the sides, ensuring a thorough cleaning every time.

Compared to the plastic funnels I’ve used in the past, the Kimble/Kontes funnel is in a completely different league. It offers superior chemical resistance, faster flow rates, and a level of durability that I never expected from a glass product. It’s a significant upgrade and a valuable addition to our disaster relief equipment.
