Problems solved by technology

[0002] At present, most of the main agarose products on the market are low-voltage endosmotic agarose, the sol temperature is relatively high (about 90-95°C), and it is not easy to dissolve. When dissolved, a large number of bubbles are generated, which is easy to overflow.
In addition, the production process of the existing agarose product produces a large amount of waste residues, resulting in a lower specific surface area of ​​the product (≤200.0m 2 / g), and the whole process takes a long time, the product quality is dark, the process continuity is poor, and the equipment utilization rate is low
