简要描述:

whatmanPTFE聚四氟乙烯直径47mm孔径0.2um7582-004Whatman Teflon(PTFE)聚四氟乙烯膜
Teflon(PTFE)膜
化学稳定性和惰性
PTFE适用于化学腐蚀性强的有机溶剂、水溶液和气体,它对大多数的酸性、碱性和溶液都有抗性,非亲水性膜,蛋白吸附力低,有很好的化学相容性。
应用
PTFE膜的一个主要应用就是净化腐蚀剂、溶液和腐蚀性强的溶液。

应用 
PTFE膜的一个主要应用就是净化腐蚀剂、溶液和腐蚀性强的溶液。这包括HPLC分析中样品过滤的非常高要求,因为任何固体颗粒都会造成柱子的*破坏。一般使用0.5μm孔径。空气和气体的消毒是由于PTFE膜的疏水性、阻止气态水。通常用0.2—0.5μm孔径。各种容器口的灭菌和发酵器、过滤罐的灭菌则使用0.2μm的PTFE膜。
