Cleaned and individually bagged, these funnels are free of particles or residues that could contaminate your samples. Use them to move liquids or powders from one container to another, then toss them when you’re done. These funnels have ridges that stop liquids from swirling around the inside, which helps them drain faster. Made from polypropylene, these funnels hold up to use with chemicals.

To prevent cross contamination, toss these funnels after you transfer liquids or powders from one container to another. These funnels are polypropylene, so they’re lightweight and good for most general purpose applications, even chemicals. Ridges stop liquids from swirling for fast drainage.

Gently add liquid to not disturb other contents. These funnels are often used for chromatography. Instead of an open spout, they have four small outlets on the side of the spout. As you pour, the liquid splits into even streams and flows down the container wall, calmly pooling at the bottom.
