With low-extractable, low-binding, pure polypropylene (PP) membrane filters and pre-filters are the preferred medium for HPLC applications with low detection levels and help prolong column life.
PP membrane filters are composed of 100% --a durable, flexible polymer that resists distortion, tearing, and breaking--making them suitable for rough handling or forceps use. Their absolute pore sizes provide fast flow rates and consistent, accurate results while their high thermal stability gives them autoclave suitability and significantly higher post-sterilization throughputs than cellulose acetate membrane filters. With their broad chemical compatibility and pH tolerance from 1-14, our polypropylene membranes are highly acid and base resistant and well-suited for use with aggressive non-aqueous samples. Our polypropylene filters have extremely low extractable levels, provide accurate analysis results, and have the ability prolong column life in sensitive ion chromatography applications. Because of these high-purity results, they are also well suited for many biological application such as cell growth, tissue culture media sterilization, and pharmaceuticals. They also exhibit negligible protein binding, which is essential for maximum sample recovery of critical, small-volume protein samples. In addition to these properties, high levels of adsorbency make our polypropylene membranes the filter of choice for high-performance liquid chromatography (HPLC) mobile phase applications.
With the examination and verification of Shaanxi Administration of Safe Production, Starlab acquired the title of Second –class of Safety Production Standardization Enterprises in 2013.We provide FILTSTAR Syringe Filters,WINSTAR Syringe Filters and Sterile Syringe Filters etc.
