The LK-1700 RootExu Plant Root Exudate Automatic Extraction System is based on the vacuum negative pressure principle and equipped with a fully automated peristaltic pump, the LK-1700 RootExu system enables precise control of negative pressure intensity, duration, and culture solution volume, achieving efficient and accurate extraction operations. The system mainly consists of an injection host (with integrated peristaltic pump), nutrient solution storage bottle, extension tubes, extraction host (with integrated vacuum pump), rhizosphere exudate sampling device, and a battery-powered system. Integrated with a unified operation control system, it allows fully automated extraction of soil solutions and root exudate solutions, significantly improving convenience and efficiency. Additionally, the system is equipped with soil moisture, temperature, and electrical conductivity sensors, enabling simultaneous monitoring of surrounding soil environmental factors for comprehensive soil environment data. It is widely used in monitoring and research within agriculture, forestry, and ecological soil studies.
