The core of vacuum freeze-drying technology, as a cutting-edge technology, is to cleverly transform the moisture in the material from liquid to solid, and further sublimate it to gas under high vacuum environment, thereby achieving efficient dehydration. This revolutionary approach not only demonstrates great potential in production practice, but also shines brightly in the fields of scientific research exploration and environmental protection testing.

Recently, the School of Urban and Environmental Sciences at Peking University has undergone an important upgrade of its research facilities——Successful installation of LGJ-12A standard freeze dryer. This device has settled in the Fourth Ring Road of Beijing and set sail, marking a new stage of more precise and efficient research in environmental science fields such as soil and water quality for the college. LGJ-12A, with its excellent performance, will become a capable assistant to the research team of the college.

The LGJ-12A freeze-drying machine, as a star product in the Beijing Fourth Ring Road departure bell jar series, has won widespread favor from universities, research institutions, and small enterprise laboratories due to its compact design (desktop friendly), 0.12 square meters freeze-drying area, -65 ℃ low-temperature cold trap, and<1Pa ultimate vacuum degree. The large opening design of its cold trap facilitates sample pre freezing, eliminating the need for additional low-temperature refrigerators.

In addition, the device also uses high-quality materials, such as aviation grade acrylic material organic glass cover that is resistant to high temperature and low pressure, ensuring that users can clearly observe the entire freeze-drying process and grasp the details. The waterproof intake valve is made of stainless steel material and equipped with manual flow control, which not only ensures experimental safety, avoids sample splashing, but also ensures the durability and sealing of the valve body.

Starting from the Fourth Ring Road in Beijing, we always keep up with market demand and are committed to providing diversified vacuum freeze-drying solutions for global customers. The excellent performance and thoughtful after-sales service of its products have won widespread praise in the market. For those of you who pursue efficient and precise research experience, the Beijing Sihuan Qihang Freeze Drying Machine is undoubtedly an ideal partner for freeze-drying research in universities.
