1. Fold the filter paper in two folds and fold it into a 90° center angle.
2. Put the folded filter paper into three layers on one side and one layer on the other to form a funnel shape.
3. Put the funnel-shaped filter paper into the funnel. The edge of the filter paper should be lower than the edge of the funnel. Pour some water into the funnel mouth to make the wet filter paper adhere to the inner wall of the funnel, and then pour off the remaining water for use.
4. Install the funnel with the filter paper on the filter funnel rack (such as the ring of the iron stand), place the flask or test tube that receives the filtrate under the funnel neck, and place the tip of the funnel neck against the wall of the receiving container. .
5. When injecting the liquid to be filtered into the funnel, hold the beaker with the liquid on the right and hold the glass rod on the left. The lower end of the glass rod is placed close to the three layers of filter paper, and the beaker cup is tightly attached to the glass rod until the liquid flows into the funnel.
6. When the liquid passes through the filter paper and flows down the neck of the funnel, check whether the liquid flows down the wall of the cup and inject into the bottom of the cup. If not, move the beaker or rotate the funnel so that the funnel tip fits against the beaker wall.
