It also avoids the potential for etching from harsh solvents. The promise of leakproof operation with the Teflon* TFE stopcock sealed the deal for me, ensuring minimal sample loss and mess.
Real-World Testing: Putting Nalge Nunc Separatory Funnels, Polypropylene, Squibb, Pear-Shape, NALGENE 4300-1000 to the Test
First Use Experience
My initial test of the Nalge Nunc funnel took place during a field study focused on extracting natural pigments from plant samples. The extraction process involved using a solvent to separate the pigments from the plant material, followed by separating the solvent layer from the aqueous layer. The funnel performed flawlessly in the field.
I also put it through its paces in less-than-ideal conditions. It stood up to moderate wind and slight drizzle without issue. Using it was intuitive; the ergonomic pear shape made it easy to swirl and mix the liquids. No leaks or unexpected issues surfaced during my first use, which was a relief considering the value of the samples.
Extended Use & Reliability
After several weeks of consistent use in my lab and field studies, the Nalge Nunc funnel continued to impress. The polypropylene construction showed no signs of degradation or discoloration, even after repeated exposure to various solvents. Cleaning was straightforward; a simple rinse with soap and water, followed by drying, kept it in pristine condition.
Compared to my previous experiences with glass funnels that often chipped or broke with rough handling, the Nalge Nunc proved to be a champion of durability. It significantly outperformed my expectations, providing reliable and consistent results. Its rugged design made it a go-to tool for both field and lab work.
