Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example one

Referring to fig. 1 to 4, in an embodiment of the present invention, a dropper includes an elastic suction bag 1 of a disposable dropper, a glass tube body 2 of a rubber-tipped dropper, and a reinforcing connector; the elastic suction bag 1 of the disposable dropper is sleeved outside the top end of the glass tube body 2 of the rubber head dropper, and the reinforcing connecting piece is arranged outside the joint of the elastic suction bag 1 of the disposable dropper and the glass tube body 2 of the rubber head dropper.

The elastic suction bag 1 of the disposable dropper is the upper half part of the disposable dropper after being cut; the lower half part of the disposable dropper is a plastic dropper body 11; the elastic suction bag 1 of the disposable dropper is integrally formed with the plastic tube body 11; the disposable dropper is a disposable experimental device and can be discarded uniformly after use, thereby causing resource waste.

The glass tube body 2 of the rubber-tipped dropper is the lower half part of the rubber-tipped dropper; the upper half part of the rubber head dropper is a rubber suction bag 21; the bottom end of the rubber suction bag 21 is sleeved outside the top end of the glass tube body 2 of the rubber dropper; the rubber suction bag 21 is a rubber product, and due to the change of physical and chemical properties and mechanical properties caused by the comprehensive action of internal and external factors in the using process, the rubber suction bag is easy to age and crack and loses the using performance, so that a tester cannot suck a solution when using the rubber suction bag, and the testing efficiency is influenced; the glass tube body 2 of the rubber-head dropper is a glass product, is high-temperature resistant, corrosion resistant, not easy to age and durable; after the upper half part of the rubber head dropper is aged, the lower half part can only be discarded, and the waste of resources is caused.
