Product Description:

(1) Four-fluorine piston switch sand core funnel/porous plate funnel, convenient for controlling the flow rate of liquid during the experiment

(2) Glassware with sand cores should be handled to avoid sudden temperature changes, especially when being dried in an oven. Always place it in an oven at room temperature before heating, and do not directly place it in a high-temperature oven. When removing it from the oven, wait until it has cooled to room temperature before taking it out. Otherwise, due to the differing thermal expansion coefficients of the sand core and glass wall, cracking is likely to occur.
