AI Technical Summary

Technical Problem

Existing rubber-headed droppers lack auxiliary stabilization structure, especially when using longer droppers or absorbing solutions with larger concentrations, the absorption effect is poor.

Method used

A laboratory rubber head dropper structure is designed, including a tube body, a rubber cap and a tube sleeve. The outer side of the rubber cap is bonded with an annular rubber strip, and the memory wire is installed inside. The tube sleeve is connected to the support rod to form a firm whole, which uses the elastic restoration performance of the memory wire to enhance the suction force of the rubber cap.

Benefits of technology

Through the design of lifting ears and support rods, the stability of the dropper is improved, making it easier to absorb or drip the solution; the elastic recovery performance of the memory wire is used to improve the suction force of the rubber cap, which is suitable for solutions of different concentrations.

Abstract

The utility model belongs to the technical field of laboratory rubber-head droppers, and discloses a laboratory rubber-head dropper structure which comprises a tube body, a rubber cap and a tube sleeve, the rubber cap sleeves the top end of the tube body, a group of annular rubber strips are adhered to the outer side of the rubber cap, a memory metal wire is arranged in each annular rubber strip in a penetrating manner, the tube sleeve movably sleeves the tube body, and the tube body is sleeved with the tube sleeve. Supporting rods are fixedly connected to the outer walls of the two sides of the pipe sleeve, and lifting lugs are rotationally connected to the supporting rods. An experimenter can firmly lift the whole dropper by inserting a thumb and an index finger into the two lifting lugs respectively and then pinch the rubber cap in a matched mode, so that the tube body, the tube sleeve, the supporting rod, the lifting lugs and the rubber cap form a firm whole, the stability of the dropper can be improved, and a solution can be better sucked or dripped; by utilizing the elastic recovery performance of the memory metal wire in the annular rubber strip, the rubber cap can be assisted to better recover, so that the suction force of the rubber cap in the recovery process can be improved, and solutions with different densities can be sucked.
