The invention relates to vacuum quantitative concentration equipment and a concentration method. The equipment comprises a concentration cup, a vacuum module, an oscillation module, a water bath heating module, a waste gas recovery module, a condensation reflux module, a low-temperature evaporation-dry-preventing module and a control module, a tail pipe is arranged at the lower end of the concentration cup, so that the sample solution is centrifugally oscillated, rotationally evaporated and concentrated in a vacuum environment, the concentration effect in the sample solution can be further improved through the condensation reflux module, and the low-temperature evaporation-dry-preventing module is used for keeping the low temperature of the tail pipe positioned at the lower part of the concentration cup; in the whole process, the control module automatically coordinates the vacuum module, the oscillation module, the water bath heating module, the waste gas recovery module, the backflow module and the low-temp
