Description
Qualitative filter paper of TIMESETL●Perfect filtration effectThe qualitative filter paper of high quality cotton fiber has good particle retention effect, which can separate the sediment, aerosol precipitation and solution to get the correct characteristics. Suitable for general chemical applications.●Average flow rateQualitative filter paper works better and more effectively in experiments with the correct flow rate●Practical functionsCan be easily placed on the corresponding tools such as funnels and beakers. Widely used in chemical experiments and can also be used to filter homemade perfumes, lotions and other essential oilsructions:1. Fold the filter paper twice and fold it into a 90-degree central angle.2. The folded filter paper is opened in three layers on one side and the other side is opened 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. Soak the filter paper with water and then lean it against the funnel.4. Place the funnel with the filter paper on the funnel holder and place the tip of the funnel neck against the side wall of the receiving container.5. When injecting the liquid to be filtered into the funnel, hold the beaker right, hold the glass rod on the left, make the cup stick to the glass rod, and then flow into the funnel along the inclined posture of the glass rod. The liquid flowing into the funnel must not exceed the height of the filter paper in the funnel.6, always keep the liquid flowing down the cupification:-Color: as shown.-Material: Paper.-Diameter:11cm,4.33 inches.- Quantity: 100 sheets- Flow rate: medium.- Suitable for general chemical useage includes:1 x 100 piece set of 11 cm diameter high quality medium flow qualitative filter paper
