What is Filters? Filtration is the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. Either the clarified fluid or the solid particles removed from the fluid may be the desired product.


Types of Filters

Syringe Filter

PTFE Filter

Membrane Filter PVDF Filter


Syringe Filter Syringe filters are single-use, membrane-based devices used for the removal of particulate impurities from liquid and gas samples before analysis by methods such as HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing.


Membrane Filter Membrane filters permit the flow of liquids or gases while controlling the passage of particles and microorganisms. It is used mostly to remove bacteria, microorganisms, particulates, and natural organic material, which can impart color, taste, and odors to water and react with disinfectants to form disinfection by-products.


PTFE Filter PTFE filters are a versatile choice for size-selective samplers. The material's unique properties make it ideal for gravimetric, chemicals, and microscopic analysis of sample particulate.


PVDF membrane filters are mechanically strong, exhibit superior chemical resistance, and have high thermal stability. Available in both hydrophilic and hydrophobic options.
