Filtering Funnels
 |  |
Borosilicate Glass |
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—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.
