Details
爱西默公司生产的疏水聚二偏氟乙烯滤膜具有优良的耐热性和耐化学性。即使在很低的压差下，也能保证潮湿空气或其它气体通行无阻，而水溶液则不能透过。其性能与亲水膜正好相反。
技术参数：
材料 聚二偏氟乙烯 (PVDF) 吸附性 0.2µm膜对γ-globulin的吸附量为8µg/cm2 泡点(异丙醇) 0.2µm：0.8bar 0.45µm：0.45bar 1.0µm：0.1bar 化学兼容性 耐所有有机溶剂和强化学品，详见 溶出物 水未检出 流速 材料 空气 异丙醇 压力 Δp5 kPa Δp100 kPa 3µm 1.1 l/分/cm2 - 1.0µm 0.90 l/分/cm2 - 0.45µm 0.70 l/分/cm2 17-23ml/分/cm2 0.2µm 0.24 l/分/cm2 9-12ml/分/cm2 灭菌方式 高压灭菌(121℃或134℃)，或环氧乙烷熏蒸 厚度 100µm± (10µm) 应用领域：
用于空气、气体和化学品的过滤；
PVDF 滤膜具有极强的化学兼容性，能胜任绝大多数有的有机溶剂和强腐蚀化学品的过滤；
在过滤水相溶液时，必须先用乙醇或异丙醇预浸润后，水相溶液才能滤过。
