Plastic Funnels for Harsh Chemicals
Transfer acids, solvents, and other harsh substances with these funnels—they’re more chemical resistant than standard plastic funnels. Unlike glass or porcelain funnels, they won’t chip or shatter. A nonstick finish keeps material from clinging to the sides, so you can transfer every last bit.
Style B have a straight spout that helps prevent clogs when transferring powders or viscous liquids.

Glass Funnels
Made of borosilicate glass, these funnels withstand higher temperatures and harsher chemicals than plastic funnels. Unlike some plastic, glass doesn’t leach, meaning it won’t contaminate samples. These funnels meet strict ASTM standards for laboratory glassware material and dimensions.
Style A funnels are often used with filter paper. The angled spout opening helps liquids flow smoothly without splashing.

Filtering Funnels
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.
Borosilicate glass funnels stand up to harsher chemicals than porcelain funnels but are more fragile. They also filter finer particles without filter paper. Since they’re clear, they’re best for highly precise work where you need to closely monitor the process.
