Sterlitech 亲水性聚酯（PETE）膜 滤膜 PET3047100
Polyester (PETE) Membrane Filters, 3.0 Micron, 47mm, 100/Pk
亲水性聚酯（PETE）膜过滤器
我们耐溶剂的亲水性聚酯径迹蚀刻（PETE）膜由薄型、半透明的微孔聚酯薄膜制成，非常适用于血液分析、显微分析以及样品的常规过滤。
这些PETE膜表面光滑平整——提供出色的颗粒可见性和更快的分析速度——并且含有精确数量的孔，可捕获所有大于其孔径的颗粒。与聚碳酸酯膜相比，PETE膜在材料特性和应用上类似，但具有更高的耐溶剂性。我们的聚酯径迹蚀刻（PETE）膜通过两步专有制造工艺生产，并在整个过程中遵循最高质量标准。这一独特工艺可提高膜孔径和孔密度的控制力，确保每片聚酯膜的物理特性精确符合客户规格。
