Abstract

This is a kind of miniflow control chip integral device of highly efficient constant temperature system. It includes a temperature thermostat and a micro 3D controller. The 3D controller is fixed on one side of the bed flatform, and the temperature thermostat is made up of two micro metal incubators, one on the top and the other on the bottom. In the incubators there are circulate conduits for the temperature-controlling working substance, and between the incubators the miniflow control chips are set on the flatform. Also there are the sustainer and the spiral controlling nuts between the incubators to make the height between two incubators almost the same as the thickness of the chip. This invention is miniflow control chip integral device of the integrated temperature thermostat, and using it can make the experiment run in the temperature set before and cancel the perturbance of the temperature in and outside the system. As a resut, we can greatly improve the replaying ability of the experiment and widen the use and researching area of the electrophoretic chip.

Description

technical field [0001] The present invention is a microfluidic chip integrated device integrating a high-efficiency constant temperature system. Specifically, the constant temperature device is directly integrated into the capillary electrophoresis chip system to take advantage of the high-efficiency constant temperature of the thermostat. The integrated system is suitable for various chips. Detection technology (such as optical detection, electrochemical detection and mass spectrometry detection, etc.) belongs to the field of chemistry. Background technique [0002] The micro-total analysis system is one of the research frontier hotspots in analytical science. The micro-total analysis system integrates the entire analysis process in the laboratory, such as sample processing, sample filtration, sample separation, and sample detection, on a small chip, which can realize the automation and miniaturization of the entire analysis process. [0003] An impo...
