Description

A device for mixing materials in test tubes

technical field

The utility model relates to a chemical laboratory instrument, in particular to a device for mixing materials in a test tube used for stirring the solution in the test tube in chemical experiments.

Background technique

In the previous experiments, glass rods were usually used to stir the solution in the test tube. Due to the small diameter of the test tube, on the one hand, when using glass rods, the movement range is small, which is inconvenient to operate and the stirring effect is not good; On the one hand, it is easy to collide with the test tube wall to cause the test tube to break, and there is a greater potential safety hazard in the operation process. In addition, in the experiment, the liquid in the test tube is usually shaken by shaking the test tube. Although the operation is simple, the mixing effect is poor, and the solution in the test tube is easily splashed from the test tube mouth, causing pollute.

Utility model content

In order to overcome the above technical problems, the utility model provides a device for mixing materials in test tubes with reasonable structure design, convenient and quick operation, good mixing effect on solutions in test tubes, and relatively safe operation.

In order to achieve the above technical purpose, the utility model adopts the following scheme: a device for mixing materials in a test tube, including a floating plug for placing in the test tube, which is made of polytetrafluoroethylene and has a cylindrical shape. The column wall is embedded with a magnet sleeve concentric with it; a number of slotted holes are distributed on the floating bolt, and the central axes of the several slotted holes are all parallel to the central axis of the floating bolt; the floating bolt is provided with a The driving sleeve is used to be sleeved outside the test tube, and the driving sleeve is made of magnetic material, which can drive the floating plug to move through the magnetic attraction force.

The utility model has the following beneficial effects: when in use, place the swimming bolt in the test tube, put the driving sleeve outside the test tube, the driving sleeve and the magnet sleeve on the swimming plug will generate suction, and when the driving sleeve slides up and down, it will Drive the floating plug to move up and down, when the floating plug moves up and down, the liquid in the test tube flows through the slot, so as to achieve the purpose of mixing and homogenizing. The utility model has the advantages of simple structure, reasonable design, good stirring effect, uniform mixing, convenient and fast operation, safety and sanitation, and remarkable practicability.

Among the figure, 1, floating bolt, 2, slotted hole, 3, magnet sleeve, 4, driving sleeve, 5, test tube.

Detailed ways

Referring to Fig. 1, a device for mixing materials in a test tube includes a swimming plug 1 and a driving sleeve 4; the swimming plug 1 is used to be placed in a test tube 5 to stir and mix the materials in the test tube 5, It is made of polytetrafluoroethylene and has a cylindrical shape. A magnet sleeve 3 concentric with it is embedded on the column wall. A number of slots 2 for allowing the materials in the test tube 5 to pass are distributed on the floating plug 1. The central axes of the slots 2 are all parallel to the central axis of the floating bolt 1; the driving sleeve 4 is set outside the test tube 5, and it is used to drive the floating bolt 1 to move axially along the test tube 5, and the driving sleeve 4 is made of magnetic materials , which can move synchronously with the magnet sleeve 3 on the floating bolt 1 through magnetic attraction.

When in use, the floating plug 1 is placed in the cavity of the test tube 5, the driving sleeve 4 is set outside the test tube 5, and when the driving sleeve 4 is held by the hand to move outside the test tube 5, the floating plug 1 is passively moved by the magnetic attraction force, thereby playing The purpose of mixing liquids.
