Featuring a 0.2 µm PTFE (polytetrafluoroethylene) membrane, this filter acts as a reliable barrier that allows air and gases to pass freely while effectively blocking aqueous liquids and moisture. Housed in a durable, chemically resistant polypropylene casing, the Vacushield is designed to withstand the rigors of laboratory suction and filtration workflows. Its universal hose barb connections ensure a secure, leak-proof fit with standard 1\/4\" to 1\/2\" (6.4 to 12.7 mm) ID vacuum tubing, making it an essential safety component for any filtration or aspiration system.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHydrophobic PTFE Membrane:\u003c\/b\u003e The 0.2 µm pore size PTFE membrane is inherently water-repellent, providing a robust sterile barrier that prevents the passage of bacteria (99.99% efficiency) and liquid slugs that could damage expensive vacuum machinery.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eVacuum Pump Protection:\u003c\/b\u003e Designed to be placed in-line between the collection vessel and the vacuum source, it prevents fluid carryover and aerosolized particulates from entering and corroding pump internals.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eLarge 50 mm Filtration Area:\u003c\/b\u003e The 19.6 cm² effective filtration area ensures high airflow rates even at low differential pressures, preventing bottlenecks in your filtration or aspiration speed.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eUniversal Hose Barb Connectors:\u003c\/b\u003e Features stepped hose barbs that accommodate a variety of tubing sizes, ensuring a tight friction seal without the need for specialized adapters.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eCatalog Number:\u003c\/b\u003e 4402\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003ePore Size:\u003c\/b\u003e 0.2 µm\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMembrane Material:\u003c\/b\u003e Hydrophobic PTFE\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eHousing Material:\u003c\/b\u003e Polypropylene\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eDiameter:\u003c\/b\u003e 50 mm\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eConnections:\u003c\/b\u003e Stepped Hose Barbs (fits 6.4 – 12.7 mm \/ 1\/4\" – 1\/2\" ID tubing)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSterility:\u003c\/b\u003e Non-Sterile (Standard Grade)\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMax Operating Pressure:\u003c\/b\u003e 1.0 bar (15 psi)\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSuction \u0026amp; Aspiration Systems:\u003c\/b\u003e Critical for cell culture media aspiration, preventing biohazardous aerosols from contaminating house vacuum lines or exhausting into the lab environment.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eSterile Venting:\u003c\/b\u003e Ideal for venting small fermentation tanks, carboys, and bioreactors to allow gas exchange while maintaining a sterile internal environment.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eMaintenance Reduction:\u003c\/b\u003e By stopping moisture and particulates at the source, the Vacushield significantly extends the service intervals of oil-sealed and dry diaphragm vacuum pumps.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eChemical Compatibility:\u003c\/b\u003e The PTFE and polypropylene construction offers broad resistance to common laboratory solvents and acidic\/basic vapors often found in chemical filtration.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\u003cp style=\"margin: 0; font-size: 0.8em;\"\u003e\u003ci\u003eAll product names, logos, and brands are property of their respective owners.\u003c\/i\u003e\u003c\/p\u003e","brand":"Pall","offers":[{"title":"Default Title","offer_id":44498413486332,"sku":"2071","price":40.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/pall-4402-vent-filter-vacushield-02-um-pore-50-mm-disc-with-hose-barb-3-filters-filters-pall-640881.jpg?v=1757544918","url":"https:\/\/lifesciencestrading.com\/products\/pall-4402-vent-filter-vacushield-0-2-um-pore-50-mm-disc-with-hose-barb","provider":"Life Sciences Trading","version":"1.0","type":"link"}
