Working;
❖To fill medicine in a syringe, its needle is inserted into a medicine pot.
❖When the piston is pulled outward, the air pressure in the syringe barrel is
reduced.
❖As a result, there occurs formation of partial vacuum in the barrel.
❖ Liquid flows from the region of high pressure to the low pressure.
Therefore, the medicine in a pot is filled into the storage cylinder(barrel).
