Random mute reagent oscillator

Abstract

The invention discloses a random mute reagent oscillator, comprising a mute oscillating assembly and an oscillation control system for controlling the random oscillation of the mute oscillating assembly, wherein the mute oscillating assembly comprises a bottom shell; a bearing support plate is fixedly installed in a bottom shell; two groups of direct current (DC) linear motors are horizontally installed on the upper surface of the bearing support plate, and are vertically distributed; the upper surface of a stator base of each DC linear motor is fixedly connected with an elastic fixation strip, which is used for withstanding the rotational torque force generated during asynchronous driving of the DC linear motor, by means of a plane bearing; the top ends of the elastic fixation strips arefixedly connected with an oscillating plate together; a balance spring is connected between the bottom face of the oscillating plate and the internal bottom face of the bottom shell. The random mute reagent oscillator is reasonable in structural design, can be used for performing orderly oscillation and random oscillation, provides a real and good experimental environment for a liquid experiment,and also reduces the noise in an oscillator working process.

Description

technical field [0001] The invention relates to the technical field of oscillators, in particular to a silent oscillator for random reagents. Background technique [0002] In liquid experiments, it is often necessary to stir and mix the reaction liquid. Commonly used instruments include oscillators, shakers and magnetic stirrers. Magnetic stirrer is a laboratory instrument for liquid mixing, mainly used for stirring or simultaneously heating and stirring low-viscosity liquid or solid-liquid mixture. Its basic principle is to use the principle of the same-sex repulsion and opposite-sex attraction of the magnetic field, and use the magnetic field to push the magnetic stirrer placed in the container to perform circular rotation, so as to achieve the purpose of stirring the liquid. With the heating temperature control system, it can heat and control the sample temperature according to the specific experimental requirements, maintain the temperature conditions required by the ex...
