DNA synthesizer and synthesis method

Abstract

The invention relates to the technical field of DNA synthesis, in particular to a DNA synthesizer and a synthesis method. the DNA synthesizer comprises showering air-drying equipment; a protection device; a backplane printing device; and a positive pressure air source and a negative pressure air source, wherein the positive pressure air source is communicated to the spray head and the air knife assembly, and the negative pressure air source is communicated to the air exhaust pipeline, the liquid drainage hole and the spray head. Through cooperative use of the motion control card, the electric drive controller, the positive pressure air source and the negative pressure air source, motion control and electric drive control of the nozzle printing equipment mechanism are achieved. To-be-cleaned objects on the stations can be cleaned, and the functions of air showering and air drying are achieved; the bearing mechanism has the function of automatically adsorbing the to-be-cleaned object, and the to-be-cleaned object can be fixed. cleaning liquid can be prevented from polluting other stations and equipment; rapid recovery of waste liquid can be achieved, the waste liquid is rapidly extracted, and accumulation of the waste liquid on the bearing mechanism is prevented; and residual gas can be pumped away, the influence on the external environment is reduced, and waste liquid steam is prevented from polluting the working environment.

Description

technical field [0001] The invention relates to the technical field of DNA synthesis, in particular to a DNA synthesizer and a synthesis method. Background technique [0002] A DNA synthesizer is an instrument that can automatically perform chemical synthesis, and can automatically connect amino acids and / or nucleotides according to design. [0003] Before performing relevant operations on the substrate, the substrate needs to be cleaned, because the cleanliness of the substrate itself has a crucial impact on the subsequent operations and the quality of the product after the operation is completed. However, in the existing cleaning device, after cleaning the substrate, there will be liquid remaining on the bearing mechanism carrying the substrate, and steam gas will be generated during the cleaning process, and the remaining liquid and steam gas will pollute the working environment. The random discharge of the residual liquid and gas generated during the cleaning process wi...
