Abstract

A suspended magnetic stirrer is composed of a common magnetic stirrer module, a suspended magnetic stirrer module, a special stirring cup, an iron frame and wires. The ordinary magnetic stirrer module and the suspended magnetic stirrer module of the suspended magnetic stirrer are connected by wires, the suspended magnetic stirrer module is fixed on the iron frame with fixing screws, and the special stirring cup is placed on the ring of the suspended magnetic stirrer. The suspended magnetic stirrer module is composed of shell, electrode, electrode frame, bearing ball, gear, motor, and fixing screws. The electrode is fixed on the electrode frame. The lower part of the electrode frame has serrations and is connected to the motor through gears. There are bearing balls between it and the shell, and there are fixing screws at the rear of the suspended magnetic stirrer module. The suspended magnetic stirrer can stir the solution while adding other solutions dropwise to meet special experimental requirements.

Description

A suspended magnetic stirrer

technical field

The utility model relates to a magnetic stirrer and a beaker, in particular to a suspended magnetic stirrer and a matching special beaker.

Background technique

Nowadays, magnetic stirrers are used in many experiments, but there is no magnetic stirrer that can solve the problem of dripping while stirring. In order to meet the experimental requirements, it is very necessary to design this kind of suspended magnetic stirrer.

Utility model content

In view of the above problems, the utility model provides a suspended magnetic stirrer, which can stir the solution while adding the solution dropwise.

The technical solution adopted by the utility model to solve the technical problem is: it is composed of a common magnetic stirrer module, a suspended magnetic stirrer module, a special stirring cup, an iron frame and a wire. The ordinary magnetic stirrer module and the suspended magnetic stirrer module of the suspended magnetic stirrer are connected by wires, the suspended magnetic stirrer module is fixed on the iron frame with fixing screws, and the special stirring cup is placed on the ring of the suspended magnetic stirrer. The suspended magnetic stirrer module is composed of shell, electrode, electrode frame, bearing ball, gear, motor, and fixing screws. The electrode is fixed on the electrode frame. The lower part of the electrode frame has serrations and is connected to the motor through gears. There are bearing balls between it and the shell, and fixing screws are arranged at the rear of the suspended magnetic stirrer module. There is a hole at the bottom of the special mixing cup, which is shaped like a Buchner funnel, and there is a valve underneath, which can adjust the flow of the released liquid at any time.

The beneficial effect of the utility model is that the ordinary magnetic stirrer solves the problem that it cannot be added dropwise while stirring in the test.
