The Spring-Free Packed HPLC Column (SAC) maintains constant compression of the packing layer due to the restoring force of the spring inside the column, preventing voids from occurring in the packing layer even after prolonged use.

Product Features

· The column can be charged using an external spring column charging system, making installation simple. Once installed, there is no need to reassemble or disassemble the column, ensuring stability of the column bed.

· Conventional free-packed HPLC columns may develop voids over long-term use. However, the SAC column uses the consistent restoring force of the spring to keep the piston head compressing the column bed at a constant pressure, preventing voids from forming even after prolonged use and thereby extending the column's lifespan.

· The spring column charging system allows for the charging of multiple specifications of columns with a single setup, making it economical.

· Since it does not use electricity, it can be used in explosion-proof areas.

Product Advantages

· The piping layout is more compact than that of existing products.

· Unique design and specialized processing technology have been used to develop the distribution and collection plates, resulting in excellent column performance.
