About CHROMAFIL disposable syringe filters O-45-3 membrane material polytetrafluoroethylene (PTFE) pore dia. 0.45 m, membrane dia. 3 mm

CHROMAFIL disposable syringe filters O-45-3 with a polytetrafluoroethylene (PTFE) membrane material, featuring a pore diameter of 0.45 m and a membrane diameter of 3 mm, are designed for filtration in chemical, pharmaceutical, and analytical applications. These compact flat membrane filters have a cylindrical shape with a circular filter membrane, offering high chemical resistance and thermal resistance. With odourless and hydrophobic properties, they provide high chemical purity during sample preparation and purification processes. The filters are easy to store in a dry, cool environment away from direct sunlight. With a structure of CF2-CF2 polymer chain, PTFE (Polytetrafluoroethylene) exhibits insolubility in water and most solvents, making it ideal for various laboratory-grade applications.
