Sterlitech’s comprehensive range of membrane, syringe, and capsule filters are exclusively selected to represent the industry’s highest quality manufacturing standards, product performance, and application support for laboratory-scale filtration.
Our filtration devices have been rigorously tested and optimized to reduce process times, increase analytical efficiency, and produce consistent, measurable results. We offer polymeric, glass fiber, and ceramic membranes--in all standard diameters and a range of pore sizes--as disc/sheet filters or housed within syringe and capsule devices for single-use applications. Sterile and non-sterile options are available, along with a multitude of other custom features to accommodate end-users' diverse needs.
Polypropylene (PP) membranes have long been used across laboratory, pharmaceutical, medical device, and microelectronics industries. Their inherent hydrophobicity, broad chemical compatibility, and reliable airflow performance made them a preferred material for solvent filtration, particle control, and venting applications. As availability of polypropylene membrane products decreases, engineers and process specialists are evaluating alternative materials to maintain performance and supply continuity.
Oleophobic defines a material with either an innate resistance or a special surface treatment to resist wicking of low surface tension liquids. Derived from the Greek words oleum (oil) and phobos (fear), oleophobic literally means “oil-fearing”, these materials repel oil and oil-like substances, making them essential for protecting sensitive components. One way to determine a material’s oleophobic property is by observing how a liquid droplet beads on the surface—the wider the contact angle, the greater the resistance to wetting.
