TD-G25 series is a series of gel filtration resins made of dextran as raw material and epichlorohydrin as cross-linking agent, with hydrophilic and porous characteristics, commonly used in biological samples such as proteins, polysaccharides and nucleic acids, buffer replacement, desalination and removal of small molecules, but also can be used for the separation and purification of polypeptides and oligonucleotides, as well as the separation and purification of antibiotics, chemically synthetically synthesized drugs and natural products, but also can be used for the purification of nanomaterials in the chemical industry and the environmental protection field, such as wastewater treatment.
TD-G25 separates molecules of different sizes according to the working principle of molecular sieve, based on the different retention time of molecules in the chromatographic column.
TD-G25 is divided into the following four types according to the particle size: TD-G25 C i.e. coarse particles, TD-G25 M i.e. medium particles, TD-G25 F i.e. fine particles, and TD-G25 SF i.e. super-fine particles.
