SDA Chromatography system

SDA is a medium-sized all-in-one system.


Protein purification

 Nucleic acid purification

Vaccine purification

Polysaccharide purification

 Blood products

 Peptide purification


Dynamic mixer:2ml mixing chamber(optional:0.6ml/5ml).

Variety of UV detector module options. External fiber optic flow cell.

Conductivity detector:0-999.99mS/cm,temperature compensation possible.

Technical Features

•SDA is the space saving solution while maintain the same modern appearance as SCG-P. Its automation capability can be greatly extended through the additional valve installed externally. SDA is a high performance-to-cost ratio product introduced to meet various customers’ need.

•Powerful SCG operation software offer intuitive and flexible method editor, system controller and data analysis tool. Please note that the operating software is free for upgrade during the product lifetime.

•Can work with various brand chromatography column from domestic or international suppliers.

•SDA-030 can satisfy milligram level purification need; SDA-100 can satisfy gram level purification need.
