Whatman徑跡蝕刻膜是使用技術制造的高精密膜，膜內孔徑尺寸分布窄，孔徑一致性高。脂質體中常用這一系列的Cyclopore聚碳酸酯膜和Nuclepore聚碳酸酯膜。聚碳酸酯膜是親水性的，可以選擇不同的孔徑規(guī)格和尺寸規(guī)格。

Whatman Polycarbonate Membrane Filters are high-precision membranes with narrow pore size distribution and high pore size consistency. Cyclopore polycarbonate membranes and Nuclepore polycarbonate membranes are commonly used in this series. Polycarbonate membranes are hydrophilic and can be selected with different pore sizes and Dimension sizes.
