Abstract

The invention provides a micro-reactor, which can maintain thermal stability, is low in cost and is disposable after use. The micro-reactor includes: a reactor outer tube, a reactor inner tube, two supporting rings, two seal caps, two filter screens and two sealing plugs. The reactor inner tube is sleeved with the reactor outer tube to form an air gap. Bulge rings of the supporting rings are embedded into the air gap at the two ends of the reactor outer tube and the reactor inner tube through interference fit. Holes are formed in the seal caps along axial lines and serve as an inlet and an outlet of the disposable thermal-stable micro-reactor. The filter screens are respectively located at the inner sides of the seal caps. The micro-reactor has good heat insulation property and simple structure, is easy to manufacture, is low in cost, has high adaptability, and can be applied to biochemical analysis, especially calorimetric principle detection of environmental toxins.

Description

technical field [0001] The invention relates to a thermally stable microreactor, in particular to a thermally stable microreactor for one-time use, which can be applied in the fields of biosensors and biochemical analysis. Background technique [0002] Microreactors generally refer to reaction systems with fluid channels on the order of microns to millimeters. Their unique advantages are the enhancement of mass and heat transfer processes and the improvement of flow modes. Engineering and chemical synthesis, preparation, and micro energy systems have a broad application background. [0003] The signal-to-noise ratio of signals and parameters in microreactors is low, and thermal stability has a crucial impact on the control of internal reactions and the measurement accuracy of parameters such as internal temperature fields. Traditional microreactors have limitations in maintaining thermal stability. sex. Used for the analysis of environmental toxicants, such as heavy metals...
