What can be used for filtration instead of glass funnel in Gravimetric Analysis?

In gravimetric analysis, alternatives to a glass funnel for filtration include filter paper and sintered glass funnels, which can effectively separate precipitates from the supernatant. Additionally, membrane filters made from materials like nylon or cellulose can be employed for fine particle retention. Vacuum filtration setups using Buchner funnels can also enhance the efficiency of the filtration process.
