When in use, first pull out the top control board 10 to completely misalign the first discharge hole 7 and the second discharge hole 11 and then close the discharge pipe 5, and then put the reactants into the storage bin 3. If 60 cm³ of reactants need to be released, pull out the control board 10 below the capacity mark 13 (60 cm³) and push the top control board 10 back to its original position to allow the reactants to enter the discharge pipe 5. After the reactants enter the discharge pipe 5, pull out the top control board 10 to close the discharge pipe 5, and finally push the control board 10 below the capacity mark 13 (60 cm³) back to its original position to release 60 cm³ of reactants.

When in use, first pull out the top control board 10 to completely misalign the first discharge hole 7 and the second discharge hole 11 and then close the discharge pipe 5, then open the box cover 16 and put the reactants into the storage bin 3. If 60 cm³ of reactants need to be released, pull out the control board 10 below the capacity mark 13 (60 cm³) and push the top control board 10 back to its original position to allow the reactants to enter the discharge pipe 5.
