Manufactured to meet research and production requirements, the Whatman PTFE Membrane Filters, specifically the Te36 model with a diameter of 47 mm and a pore size of 0.45 µm, offer exceptional chemical stability and inertness. These filters are designed for applications involving aggressive organic solvents, strong acids, and alkalis, making them ideal for HPLC analysis sample preparation. With a thickness of 190 µm, these filters boast a bubble point of 0.9 bar and an air flow rate of 30 ml/min/cm2 at a differential pressure of 3 mbar. When subjected to a higher pressure of 0.9 bar, their water flow rate increases to 40 ml/min/cm2.
