The operation and control of EX1600AS autosampler, which can easily implement the whole process from sample injection to analyzing result, is made entirely by software.

The capacity of EX1600AS can be adjusted from 12 vials to 768 wells. 2 Micro well plates according to SBS standards; 96-well high/low and 384-well low formats; 48-vial or 12-vial trays.

Three injection modes: as Full loop, partial loopfill and μL pickup mode.

The application of advanced sampling technology can achieve rapid sampling and cycle cleaning, and efficient needle track cleaning can achieve low residue.

When using perforated plates or sample bottles, such articles may be used openly or sealedly.

Established in 1998, Shanghai Wufeng Scientific Instruments Co., Ltd. (Wufeng Instruments) is a high-tech enterprise integrating development, design, production and sales. Through over 10 years of its efforts, Wufeng Instruments has become one of the key domestic manufacturers of HPLC, and its products include other chromatographic analyzers and related devices, software and accessories.

"Innovative, Leading and Considerate" reflects Wufeng's culture.

Innovative: Innovation is the cornerstone of our success. Over the past more than a decade, we have, with the spirit of innovation, independently developed outstanding analytical instruments, from the initial chromatographic data processor to the current liquid chromatograph as our main products. We hold 100% of intellectual property right in “Wufeng” brand products. We have stressed on fund and manpower input in development, and by making full use of the latest technology of micro-electronics and precision machinery processing, regarding international top products as benchmark, endeavored to overcome technological problems at home and abroad so as to produce the products reaching international advanced level and meeting needs of customers.

Leading ： We will never be content with status quo, and will continue to seek a breakthrough. And we have a strong desire of self-perfection to constantly win the market. At present, we have two major series of HPLC, i.e. LC-100 and EX1600 to meet the needs of customers. Our products have gradually gained the recognition from market in terms of quality, from the top-in-sale chromatographic data processor in domestic market 10 years ago to the ceaseless increase in the popularity and market share of HPLC at present time. In the following several years, we will continue to introduce new products and actively exploit the market and various industrial fields.

Considerate: We treat our customers in good faith, and develop and produce our products in a scrupulous manner. All our product promotions and technical exchanges are conducted based on rigorous scientific approach, never misleading customers. We also pay attention to the communication with customers, in order to constantly perfect our products according to their feedback.

Wufeng Instruments has focused on its every link in details. In terms of development, consistently taking world top instruments as our benchmark, we have made repeated test and demonstration hundreds of times; in production, we are the first domestic manufacturer to test and inspect components and whole instruments by using all-digital monitoring system; in terms of selling, we spare no efforts to provide our customers with better cost-performance products and excellent after-sale service, always paying attention to the perception of customers.
