Characterized by well-defined physical properties suited for technical use, the Whatman PTFE Membrane Filters, specifically the 0.45 µm, Ø 25 mm variant, boast a thickness of 190 µm. These filters exhibit exceptional bubble point resistance at 0.9 bar, ensuring reliable filtration performance. With an air flow rate of 30 ml/min/cm² under a differential pressure of 3 mbar, and a water flow rate of 40 ml/min/cm² under a differential pressure of 0.9 bar, these filters offer efficient filtration capabilities. Their PTFE composition makes them resistant to aggressive organic solvents, strong acids, and alkalis, making them ideal for HPLC sample preparation and air and gas sterilization applications.
