Hangzhou Skala Filtration Technology Co., Ltd. was established in 2013, specializing in the research and development, production, and sales of compressed air purification and liquid nitrogen generators. It is also the authorized agent of Noblegen brand liquid nitrogen generators in China.

Traditional research laboratory facilities rely on bottled liquid nitrogen, which has long plagued users with rising costs and safety issues in liquid nitrogen transportation and storage. The use of on-site liquid nitrogen generators can end the traditional liquid nitrogen supply method, and its reliability and economy have been widely recognized in the market. Extracting liquid nitrogen from the air can eliminate the hassle of purchasing liquid nitrogen and provide users with a brand new option.

The SCALA brand's liquid nitrogen generator adopts a self-developed PSA pressure swing adsorption nitrogen production process, combined with a low-temperature refrigeration mechanism for cooling. The liquid nitrogen production rate ranges from 10 days to 500 liters per day, and the liquid nitrogen purity is 99.5% -99.999%.

Skala's products are widely used in various laboratory instruments and medical institutions, including sample storage, NMR nuclear magnetic resonance spectrometers, cryo electron microscopes, high-temperature conductors, observatories, aerospace, and other applications that require small amounts of liquid nitrogen.

Since selling the first liquid nitrogen generator in 2017, we have improved and redefined the term 'liquid nitrogen generator' based on user needs. Leveraging IoT technology, we have elevated this laboratory liquid nitrogen generator to a whole new level: safer, more reliable, smarter, and more economical.

Hangzhou Skala has established a professional after-sales service team. With fast service and good reputation, it is currently a professional manufacturer, service provider, and repairman of laboratory liquid nitrogen generators in China. So far, dozens of liquid nitrogen generators have been operating all over the country, from the Tarim Basin in Xinjiang to the Qinghai Tibet Plateau, from the Qinghai no man's land with an altitude of more than 4000 meters to the coast of the South China Sea.
