Abstract

The invention relates to an apparatus with combination of constant-temperature sample injection and heat-insulation flow mixing, which is composed of a constant-temperature body, a heat-insulation tapered rotary plug and a pressing cap. The heat-insulation tapered rotary plug is pressed by the pressing cap through elasticity and is located in a tapered plug hole in the constant-temperature body; the tapered plug hole and the heat-insulation tapered rotary plug are provided with three horizontal flow-in channels used for sample injection and a flow-out channel. The heat-insulation tapered rotary plug is provided with the three flow-in channels matched with the three flow-in channels in the tapered plug hole. The apparatus has compact total structure and is not liable to cause leakage, has good thermal-stability, allows sample injection in different modes, can achieve single flow-in and single flow-out, double flow-in and single flow-out and triple flow-in and single flow-out, has high automation degree and good adaptability, can be applied in the fields of biochemical analysis, bioengineering and chemical synthesis and preparation, and especially has advantages in application of calorimetric analysis and test on site.

Description

technical field [0001] The patent of the present invention relates to a sample injection confluence device, especially a combination of constant temperature sample injection and adiabatic confluence device, which can be used in various biochemical analysis, bioengineering and chemical synthesis, preparation fields, and biosensors and other fields. Background technique [0002] The technological process in the biochemical field often requires the confluence and mixing of multiple samples. A constant temperature is a necessary condition to ensure that the biochemical reaction meets the technological requirements. [0003] Calorimetric analysis is suitable for most biochemical reactions and is not affected by sample properties such as color, turbidity and electrochemistry. The detection principle of calorimetric method is simple and reliable, and it has gradually become a rapid detection and development tool in food safety, environment, medicine and other fields important direc...
