Soil freeze-drying experiment: The Fourth Ring Road installed LGJ-25C vacuum freeze dryer for the Ecological Environment Bureau of Xicheng District, Beijing

On May 10, 2024, the Fourth Ring Road and the Ecological Environment Bureau of Xicheng District, Beijing collaborated to successfully install the high-performance LGJ-25CVacuum freeze dryerThe LGJ-25C vacuum freeze dryer provides more accurate and reliable experimental data for subsequent soil analysis and environmental impact assessment. This has immeasurable value for studying the current status of soil pollution, tracking the migration paths of pollutants, and formulating effective environmental protection measures.

The LGJ-25C vacuum freeze dryer can effectively retain various chemical components in soil samples, ensuring the accuracy of key indicators such as pH value determination, organic matter content determination, fluoride determination, and available potassium determination in subsequent tests. During the installation process, the technical personnel of Sihuan not only ensured the smooth installation of the equipment, but also provided detailed answers to the teachers' questions, laying a solid foundation for subsequent scientific research activities.

With its-The LGJ-25C vacuum freeze dryer can provide an ideal freeze-drying environment for soil samples with a cold trap cooling temperature of 65 ℃ and a dehumidification capacity of 6L per cycle; Using advanced Android system control software, the LGJ-25C can not only store multiple preset or custom freeze-drying programs, but also support digital password protection to ensure data security. The system can record and store real-time data every minute, providing great convenience for researchers.

In terms of security,The LGJ-25C is equipped with comprehensive safety protection measures, including leakage protection, high current protection, freezer protection circuit, and fuses, effectively ensuring the safety of operators. The self diagnostic function of the control panel can promptly alert and take protective measures in case of abnormal conditions, ensuring worry free operation. The use of environmentally friendly refrigerants R404A and R23A balances high efficiency and environmental friendliness.
