Dispose of chemicals while keeping hazardous fumes contained. These funnels thread onto your container and have a gasketed lid that latches shut, so you can leave them in place between fills. They also have a filter to catch large particles. For easy cleaning, the filter and spout are removable.

The funnel, seal, and spout are made of high-density polyethylene, which can handle most solvents. However, avoid using these funnels with strong acids, bases, and oxidizers.

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.

Store flat then pop open to use. These paper funnels are clay coated for use with liquids and lubricants.

Separate solids and liquids. Also known as Buchner funnels, these funnels have a built-in perforated plate—use it by itself or to hold filter paper. Since the plate is built in, all solid material is collected on top while liquid filters through uncontaminated.

To speed up the filtration process, use these funnels with a vacuum flask. Place them into the flask’s stopper for an airtight seal.

Insert the wand of your vacuum conveyor in the port to move material out of these bins. They have casters, so they’re easy to wheel where needed.
