The invention discloses an improved experimental measuring cylinder which comprises a cylinder body with scale marks engraved on the surface and further comprises a piston piece which is arranged in the cylinder body in a sliding mode, and a plurality of first through holes are formed in the piston piece in a penetrating mode. The improved experimental measuring cylinder is different from the prior art, through the arrangement of the piston piece, the position of the piston piece can be set in advance according to the amount of needed liquid, then the liquid can be directly poured out, and in the liquid pouring process, when the liquid meets the requirement, the piston piece is arranged on the piston piece, so that the liquid can be poured out conveniently. The liquid automatically pushes the floating plate to move upwards and is tightly attached to the piston piece for plugging, and at the moment, the liquid below the piston piece is in the required amount; besides, even if the poured liquid is more than the
