Product Instructions

1. Fold the filter paper in half and fold it twice to form a 90 ° center angle.

2. Put the stacked filter paper in three layers on one side and open one layer on the other side to form a funnel.

3.Put the funnel-shaped filter paper into the funnel. The side of the filter paper should be lower than the side of the funnel. Pour some water into the funnel mouth to make the soaked filter paper abut the inner wall of the funnel, and then pour the remaining clear water for use.

4.Place the funnel with the filter paper on the funnel holder for filtering (such as the ring on the iron stand), and place the beaker or test tube containing the filter liquid under the funnel neck, and place the tip of the funnel neck on the wall of the receiving container. Prevent liquid splashes.

5. When injecting the liquid to be filtered into the funnel, hold the beaker holding the liquid on the right and the glass rod on the left. The lower end of the glass rod is close to the three layers of filter paper. The beaker cup is close to the glass rod. The rod flows into the funnel. Note that the level of liquid flowing into the funnel cannot exceed the height of the filter paper.

6. When the liquid flows down the funnel neck through the filter paper, check whether the liquid flows down the cup wall and pour it to the bottom of the cup. If not, move the beaker or rotate the funnel so that the tip of the funnel is firmly attached to the wall of the beaker, so that the liquid can flow down the wall of the beaker.
