Since its establishment in 2004, Beijing Shi'ankelin Purification Technology Co., Ltd. (hereinafter referred to as "Shi'ankelin") has developed into a professional enterprise with core competitiveness in the field of critical point drying technology. The company has a fixed office space of 800 square meters and a 2000 square meter product production and processing base in Yizhuang Economic and Technological Development Zone. At present, the company has over 100 management personnel and employees, and has 9 regional distribution offices (branches) across the country.

Shian Kelin has always regarded talent cultivation and technological research and development as the core driving forces for enterprise development. The company has invested a large amount of funds and achieved significant results in the research and development, quality assurance, and related technologies of critical point dryers. We have a group of expert level technical talents in the fields of supercritical fluid technology, high-pressure vessel design, precision temperature control, and materials science.

The company has multiple core inventions and utility models in the field of critical point drying technology, especially in mature technologies such as "supercritical drying equipment chamber design and safety control", "high-precision CO2 critical point drying process", and "critical point drying methods for specific biological and material samples". We have been deeply involved in the integration of precision control systems for laboratory automation equipment, the construction of microenvironments, and the research and development of complex equipment. We have overcome a series of technical difficulties in critical point dryers, achieved precise temperature and pressure control in complex environments, and ensured non-destructive and efficient sample processing.

With its professional advantages in critical point drying technology, Shian Kelin serves national key scientific research and industrial fields. Through close cooperation with numerous customers, we have received widespread praise for helping customers solve experimental process problems and improve research and production efficiency.

To further focus on our core business and expand our market, we have established a high-tech company in Jiangyin City, Jiangsu Province, focusing on the research and production of supercritical drying equipment. Taking advantage of the mature and developed supporting industrial foundation in the Yangtze River Delta region, especially its advantages in precision machining, automation control, and new materials, while better serving the booming future customers such as semiconductor manufacturing enterprises, major universities, and research institutions in the region.
