64 MM PTFE VENTING FILTER 64 mm PTFE 排气过滤器
For containers of culture media, small fermenters and other containers needing sterile ventilation, we have developed a 64 mm venting filter with a hydrophobic PTFE membrane. The membrane is reinforced with a polypropylene grid.
,适应容器培养基、小发酵罐、槽和其他器皿的无菌通风需要，我们提供先进的64mm不沾水PTFE膜排气过滤器，这种过滤器的膜使用聚丙烯格栅加固，所有材料通过USP生物研究安全VI级测试。
We offer two different pore sizes – 0.2 and 0.45 um – and two different connectors –hose nipple inlet/outlet and 1/8” male NPT. The venting filters are available in both sterile and non-sterile version. Our unique design allows high air flow at low differential pressures. 有无菌消毒和不消毒0.2和0.45um两种不同孔径、橡皮嘴出、入口和 1/8”雌NPT两种不同连接器可供选择，我们独有的设计允许低压差高流速。
