Spylx Porcelain Buchner Funnel  (Grey, Pack of 1)

Please note when using: 1. The filter paper of the funnel can not be cut too big, otherwise it will easily leak, and it should be cut properly. 2. The suction bottle needs to be moistened and then filtered. 3. Turn on the pump at the time of suction filtration, pull out the tube at the end, and then turn off the power to prevent back suction. 4. Choose the right size Brinell funnel and suction filter bottle. After completion, a small amount of pure solvent can be used to wash off the magazine on the crystalline surface. Buchner funnels are often used for filtration using vacuum or negative pressure suction.
