Abstract

Disclosed in the present invention are a liquid transfer device, a reaction device and an analysis device, the liquid transfer device being used for guiding a reaction liquid to a reaction surface of a sample carrier. A fixing portion comprises a fixing structure, the fixing structure being used for fixing a sample carrier. A first substrate comprises a first wall surface, the first substrate having a first position and a second position which are relative to the fixing portion. When the first substrate is located at the first position, the first wall surface is used for obtaining a reaction liquid, and when the first substrate is located at the second position, the first wall surface is used for guiding the reaction liquid to a reaction surface. A first driving portion is configured to drive the first substrate to perform position switching between the first position and the second position. The Mohs hardness of the first substrate is greater than or equal to 5H. The present invention can effectively control the distance between the first wall surface and the reaction surface of the sample carrier, thereby ensuring the quality of reaction liquid transfer, and avoiding damage to the reaction surface caused when the first wall surface is in contact with the reaction surface, or failure to completely transfer the reaction liquid to the reaction surface caused by an excessively large distance between the first wall surface and the reaction surface.
