Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic contaminants be introduced in sample pretreatment. HPLC disposable syringe always be used in HPLC analysis and IC analysis. Filtering sample solutions is an important step in the sample pretreatment process.
The strong hydrophilic PVDF surface not only makes it have low liquid absorption rate and high mass transfer resistance, but also is not easy to be further functionalized, and its application is greatly restricted which starting from the molecular structure of PVDF.
Hawach WINSTAR hydrophilic PVDF syringe filters with pore size of 0.22μm are brown, and pore size of 0.45μm is grey. Hydrophilic PVDF filter has very low protein adsorption and stable membrane quality and zero difference between batches ensure the reliability of analysis results. HPLC disposable syringe is mainly used for medicine filtration, gas filtration, steam filtration, high temperature filtration, and food industry filtration. Difference from hydrophilic PVDF syringe filters, disposable PVDF syringe filters contain hydrophobic membrane.
Hawach PVDF syringe filters use advanced modification technology to prepare high-quality hydrophilic PVDF products. By grafting modification on PVDF, hydrophilic groups are introduced on the surface of PVDF to give the material good hydrophilicity. Performance, while imparting new characteristics to the surface, it will not change the excellent performance of the matrix material. At the same time, the graft monomer and the surface of the substrate are combined in the form of covalent bonds, resulting in higher product stability. It not only greatly improves the compatibility of PVDF and other polymer blends, but also improves the hydrophilic PVDF, expands its application fields, increases its practical value, and can meet customer needs.
