[0002] A measuring cylinder is a glass instrument used to measure liquids. The measuring cylinder is an instrument for measuring the volume of a liquid. The measuring cylinder is a vertically long cylinder with a mouth on one side for easy pouring. The lower part has wide feet to keep it stable. The cylinder The volume range is engraved on the wall for the user to read the volume. The maximum measured volume is from several milliliters to several liters. The cylinder wall is printed with scales from bottom to top. When observing the readings, the experimenter should pay attention to the line of sight and the concave surface of the liquid. The lowest point (or the highest point of the convex liquid surface) is equal, and the accuracy of the readings observed by the staff in the experiment will affect the accuracy of adding liquid, and the experimental results will not be authoritative and true when the readings are inaccurate sex

The invention discloses a measuring cylinder placing rack with a scale magnifying function. The measuring cylinder placing rack comprises a base, vertical rods, a measuring cylinder and a magnifying lens, wherein containing marks are formed on the front end surface of the measuring cylinder; a suction cup is arranged on the bottom end surface of the measuring cylinder; two vertical rods are vertically and symmetrically arranged at the left side and the right side of the measuring cylinder; the two vertical rods are oppositely arranged on the base in parallel at an interval; linear sliding rails are arranged on the inner side end surfaces of the two vertical rods; a clamping part is connected with the inside of each linear sliding rail in a sliding manner; each clamping part is arranged in the corresponding sliding rail in a manner of sliding up and down; the magnifying lens is fixedly connected and clamped between the two clamping parts, and is correspondingly arranged in front of the measuring cylinder; and two electric telescopic frames are also symmetrically arranged at two sides of the lower end surface of the base. According to the measuring cylinder placing rack, the containing mark of the measuring cylinder is magnified through the magnifying lens, so that a worker can more accurately carry out liquid adding and observation in an experiment.
