First Use Experience
My first test of the Nalge Nunc Buchner Funnels, Polypropylene, NALGENE 4280-0550 was during a simulated survival exercise in a local wilderness area.

Cleaning is a breeze; the two-piece design allows for easy access to all surfaces, and the polypropylene is resistant to staining. I was using bleach solution for the disinfection process, and the funnel held strong.
Compared to my previous experiences with flimsy plastic funnels that cracked or warped after only a few uses, the Nalge Nunc funnel is a significant upgrade. It has consistently delivered reliable performance and proven to be a durable and dependable piece of equipment. It surpasses my expectations.
