AI Technical Summary
Technical Problem
The tangential flow filtration device has low concentration efficiency and low liquid exchange efficiency, resulting in long process time.
Method used
A tangential flow concentration unit is designed, comprising an inlet chamber, a concentration chamber, and a liquid exchange chamber. By combining the concentration membrane and the liquid exchange membrane, rapid concentration and environmental regulation of the solution to be concentrated are achieved, thereby improving the concentration efficiency. At the same time, the environment of the solution to be concentrated is regulated by the input and mixing of buffer solution to improve the liquid exchange efficiency.
Benefits of technology
It improves concentration and liquid exchange efficiency and shortens process time.
