We manufacture glass filtration apparatus in many flavors; simple filter funnels, known as Buchner funnels, funnels with vacuum takeoffs sealed on, membrane filter funnel/base sets for vacuum filtration, large capacity fritted funnels, and custom sintered glassware to meet your specific needs and requirements. We have made filtration funnels ranging from tiny (2 ml) to quite large(jacketed 12l) for use with pressure, gravity, or vacuum. You can see some of this work in the filtration glassware gallery
Fritted glass filters come in a variety of sizes and porosities -
