For laboratories and industrial settings requiring reliable filtration, these Hydrophobic PTFE Syringe Filters from Allpure Biotechnology deliver professional-grade performance. Each filter features a 13mm diameter with 0.45μm pore size, made from hydrophobic PTFE membrane that offers wide chemical compatibility and excellent corrosion resistance. The medical-grade PP housing can handle max operating pressures of 75 PSI (5.2 Bar) and temperatures up to 80°C. The filtration area of 0.65 cm² provides efficient processing, while the female Luer Lock inlet and male Luer slip outlet make connections secure and straightforward. These filters are particularly useful for fermentation air sterilization filtration and removing particles from gases and organic solvents. The hydrophobic nature means they resist water while allowing gases and organic solvents to pass through effectively. While they're not sterile, they're manufactured in ISO 9001 and ISO 13485 certified facilities with Class 10,000 cleanrooms, ensuring consistent quality. The pack of 100 gives you plenty of filters for multiple experiments or production runs. The low extractables and high flow rates make these efficient to use, saving time in busy lab environments. Whether you're working in biotech, chemical processing, or research applications, these filters provide reliable separation and purification. The quality control follows Japanese standards, so you can trust the consistency filter to filter. For the price, getting 100 quality PTFE filters is excellent value compared to many branded alternatives. They ship via DHL for fast delivery, so you won't be waiting long to restock your lab supplies.
