Embodiment 1

[0027] Such as Figure 1-5 As shown, a rubber dropper for chemical synthesis includes a rubber head 1 and a dropper 2, wherein the outer surface of the dropper 2 is provided with a scale mark 12, and the rubber head 1 includes a first rubber head 3 and a second rubber head 4 , the volumes of the first glue head 3 and the second glue head 4 are different, the end of the first glue head 3 away from the opening is fixedly connected with the end of the second glue head 4 away from the opening, the first glue head 3 and the second glue head 3 Two rubber heads 4 are fixedly connected with a rotating tube 5 at the end far away from the joint, and the rotating tube 5 is provided with a semicircular sealing protrusion 6, and the rotating tube 5 is externally connected with a flow-limiting ring 7. It is worth mentioning that, The side wall of the rotating tube 5 is provided with a limiting protruding ring 13, and the inner wall of the current limiting ring 7 is provided with a limiting ...

Embodiment 2

[0032] Such as Figure 6-7 As shown, the difference between this embodiment and Embodiment 1 is that: the side wall of the rotating tube 5 is provided with two position-limiting protrusions 21, and the upper end of the flow-limiting ring 7 is fixedly connected with a position-limiting block 22, and the position-limiting block 22 Match with the limit protrusion 21.

[0033] When this embodiment is in use, the stop block 22 can only rotate between the two stop protrusions 21, and the current limiting ring 7 is rotated until the stop block 22 is in contact with one of the stop protrusions 21, and the stop block 22 Can no longer rotate, then at this time the sealing block 8 overlaps with the sealing protrusion 6, connects the glue head 1 and the dropper 2, and performs the operation of sucking the reagent; reversely rotates the restrictor ring 7 until the stopper 22 and another stopper 21 is in contact with each other, and the limit block 22 can no longer rotate. At this time, th...

Abstract

The invention belongs to the technical field of chemical instruments, and especially relates to a rubber head dropper for chemical synthesis. The dropper comprises a rubber head and a dropper. The rubber head comprises a first rubber head and a second rubber head. One end, which is far away from the opening, of the first rubber head is fixedly connected to one end, which is far away from the opening, of the second rubber head. The ends, which are far away from the joint, of the first and second rubber heads are both fixedly connected to a rotation tube. A semi-circular sealing emboss is arranged in the rotation tube. The rotation tube is externally and rotatingly connected to a restrictor ring. A semi-circular sealing block, which is matched with the sealing emboss, is fixedly arranged inthe restrictor ring. The first rubber head and the second rubber head can be alternatively used to change the suction amount; the application range is wide; based on the scale of a magnetic slide mark, a reagent can be more accurately measured by the rubber head dropper, the operation is convenient, the reagent waste is avoided, and due to the restrictor ring, when the rubber head dropper is usedto transfer a reagent, the reagent leakage is prevented, and an experimental platform will not be polluted.

Description

technical field [0001] The invention belongs to the technical field of chemical instruments, in particular to a plastic dropper for chemical synthesis. Background technique [0002] Synthesis refers to the transformation of a substance with relatively simple components into a substance with complex components through chemical reactions. Chemical synthetic materials, also known as man-made materials and synthetic materials, are materials that are artificially processed from different substances through chemical methods or polymerization, and their characteristics are different from those of raw materials. In chemical synthesis experiments, a plastic dropper is often used. The plastic dropper is also called a rubber cap dropper. The plastic dropper is composed of a rubber cap and a glass tube. It is used to absorb or drop a small amount of liquid reagents. an instrument. Because the plastic dropper is easy to operate and has a wide range of applications, the plastic dropper ...
