Problems solved by technology
[0002] The dropper is composed of a rubber nipple and a pointed glass tube. It is an important equipment in the laboratory. It is used to absorb and transfer the experimental solution. When in use, it can only be placed vertically. cause corrosion
However, in the process of transferring the solution, the fingers pinching the nipple should provide enough friction, and a small amount of force should be used to clamp the nipple, and the strength of the person will change. Once the strength is slightly stronger, the dropper will be squeezed out The solution in the solution will cause waste, and even corrode the table top, causing human injury
And all there is this defect in existing dropper
In addition, the rubber nipple of the existing dropper relies on its own elasticity to reset, and when the dropper absorbs a liquid with high viscosity, the rubber nipple itself cannot be reset due to insufficient elasticity, resulting in failure to absorb

The invention relates to the technical field of experimental equipment, in particular to a dropper for a laboratory. The dropper comprises a dropper body, a clamping seat, spring hinges, a ring and clamping plates, wherein the clamping seat is a flat plate, a round hole for a glass tube of the dropper body to pass through is formed in the center of the clamping seat, and the upper portion of the glass tube of the dropper body is bonded in the round hole of the clamping seat; the upper portions of the two sides of the clamping seat are each provided with a clamping plate, and the clamping plates and the clamping seat are connected through the spring hinges; the inner sides of the clamping plate are adhered to the rubber nipple side surface of the dropper body; and a ring is fixedly arrangedon the outer side of each clamping plate. According to the dropper for the laboratory, the spring hinge design is adopted, the clamping plates can be reset automatically, the rubber nipple of the dropper body can be promoted to bounce, and solution dripping caused by unstable hand strength of the dropper is prevented.
