Product Details: Product name: Separating funnel Material: Glass Specifications: 60ml,125ml, 250ml Color: Transparent How to use: 1. Before using the separatory funnel, take out the cock core on the funnel neck and apply petroleum jelly, but not too much, so as not to block the flow hole. Insert the separatory funnel into the plug groove and rotate to make the oil film uniform and transparent, and rotate freely. Then close the cock, pour water into the funnel, check whether the cock is leaking, and use the water-tight separator funnel. 2. The amount of liquid added to the funnel cannot exceed 3/4 of the volume. And it is not suitable to install alkaline liquids. To prevent impurities from falling into the funnel, the plug on the funnel mouth should be covered. 3. When in use, hold the funnel ball with the tiger's mouth of the left hand, and use the index finger of the thumb to rotate the piston to control the liquid addition. At this time, the small groove of the glass stopper should be aligned and communicated with the small hole on the side of the funnel mouth, so that the liquid filling can be carried out smoothly.
