Problems solved by technology

The traditional shaking method is manual shaking, which is time-consuming, laborious, and inefficient. Each person can only shake two tubes (50ml) each time, which is the rate-limiting step for RNA extraction.
Because chloroform / isoamyl alcohol is a toxic liquid and may collapse during the shaking process, causing injury to experimenters
[0003] Most of the commonly used oscillators in the laboratory are vortex type, which can have a good effect on liquids of 0.5ml-2.0ml, but the oscillation intensity is far from meeting the requirements for large volume (50ml) liquids
In chemical experiments, liquid-liquid chemical extraction is commonly used for manual extraction with a separatory funnel, which is time-consuming and laborious and the extraction effect is not good.

Abstract

The invention provides an automatic oscillator, which comprises a rotating rod as well as a turntable and a rotating wheel a respectively fixed at two ends of the rotating rod; a mechanical arm is arranged on the turntable; the mechanical arm and the turntable are fixedly connected; the other end of the mechanical arm is provided with a column body; the column body and the mechanical arm are fixedly connected; and a plurality of cavities are arranged on the column body. Laboratory technician can be relieved from complex work through the oscillator; moreover, the working efficiency is improved.

Description

technical field [0001] The present invention relates to an automatic oscillator. Background technique [0002] Traditional plant RNA extraction can rely on kits, but some plant tissues are rich in polysaccharides, phenols, proteins, pigments, secondary metabolites and other substances, which are difficult to remove during the RNA extraction process, and the quality of kit extraction cannot be obtained High RNA. Therefore, during the RNA extraction process of such plants, it is necessary to add chloroform / isoamyl alcohol several times and shake vigorously for as long as 30 minutes, so that the RNA can be released and pigments, proteins and other substances can be removed. The traditional shaking method is manual shaking, which is time-consuming, laborious, and inefficient. Each person can only shake two tubes (50ml) each time, which is the rate-limiting step for RNA extraction. Because chloroform / isoamyl alcohol is a toxic liquid, and it may collapse during the shaking proc...
