Micro-fluidic chip structure and method for automatically preparing two alcohol concentrations

Abstract

The invention discloses a micro-fluidic chip structure and method for automatically preparing two alcohol concentrations, and belongs to the technical field of reagent preparation and micro-nanofluidic. The technical problems that manual preparation is time-consuming and labor-consuming, the accuracy is low, and preparation of various reagent concentrations cannot be carried out at the same time in the existing chemical reagent concentration preparation are solved. According to the technical scheme, the micro-fluidic chip structure comprises a solution inlet, a solution inlet runner, a micro-fluidic channel, a U-shaped resistance channel, a resistance plate, a solution outlet I and a solution outlet II, the content of the control method is as follows: two alcohol solutions with different concentrations are obtained by controlling the pressure of a pumped solution, the number of U-shaped channels of the U-shaped resistance channels and the number of the resistance plates. The automatic preparation device has the beneficial effects that the automatic preparation of various reagents with different concentrations is realized.

Description

technical field [0001] The invention relates to the technical fields of reagent preparation and micro-nano flow, in particular to a microfluidic chip structure and method for automatically preparing two alcohol concentrations. Background technique [0002] In industrial and agricultural production and scientific research, it is often necessary to precisely prepare a solution with a certain concentration of a substance. The preparation of the reagent concentration is difficult, and each link of the preparation needs to be strictly controlled. Now most of them are prepared manually, which is time-consuming and labor-intensive. Accuracy Low, and the preparation of multiple reagent concentrations cannot be performed at the same time, and only one concentration of reagents can be prepared at a time. During preparation, improper protective measures for operators are prone to personal injury accidents. Manual preparation can also easily lead to reagent contamination, and operators...

[0002] In industrial and agricultural production and scientific research, it is often necessary to precisely prepare a solution with a certain concentration of a substance. The preparation of the reagent concentration is difficult, and each link of the preparation needs to be strictly controlled. Now most of them are prepared manually, which is time-consuming and labor-intensive. Accuracy Low, and can not prepare multiple reagent concentrations at the same time, only one concentration of reagents can be prepared at a time

During preparation, improper protective measures for operators are prone to personal injury accidents

Manual preparation can also easily lead to reagent contamination. Operators need to use a variety of instruments to complete the preparation, which is inefficient and easily affects accuracy.
