如何选择合适的缓冲滤波器

无菌缓冲液过滤器
对于非堵塞性缓冲液的无菌过滤,我们推荐使用 Millipore Express® SHF(无菌、高通量)滤器或 Millipore Express® PHF(工艺保护、高通量)滤器。所有 Millipore Express® 胶囊式和筒式滤器均内置 0.2 µm PES 灭菌膜,具有高通量、易润湿、易于进行完整性测试以及广泛的化学兼容性。
对于易堵塞的缓冲液,Millipore Express® SHC(无菌、高容量)滤器是更佳的选择。这些滤器内置 0.5 µm 聚醚砜 (PES) 膜预滤器,可保护 0.2 µm PES 灭菌膜,从而最大限度地提高滤器容量。
- 对于需要确保无菌性的关键工艺缓冲液步骤,应使用 Millipore Express® SHF 和 Millipore Express® SHC 滤器。
- Millipore Express® PHF 滤器是一种经济高效的无菌缓冲液过滤方案,适用于关键性较低且可能无需无菌保证的步骤。
生物负荷降低缓冲过滤器
Milligard® PES 滤芯可作为生物负荷降低缓冲滤芯使用。这些滤芯具有流速快、通量高、润湿和完整性测试简便以及广泛的化学兼容性等特点,是经济高效的缓冲液过滤方案。
提供两种孔径规格,各自具备不同的生物负荷降低指标:
- Milligard® PES 1.2/0.2 µm 标称孔径:根据 ASTM F838 方法,通常可去除 ≥ 6 log 的微小短杆菌
- Milligard® PES 1.2/0.45 µm:根据 ASTM D3863 和 F838 方法,通常可去除 ≥ 6 log 的 Serratia marcescens

质量标准与文件
所有 Millipore Express® 和 Milligard® PES 滤器均按照经认可注册机构批准的、符合 ISO 9001 质量管理体系标准的质量管理体系进行设计、开发和制造,并附有质量证书。
Millipore Express® SHF、Millipore Express® SHC 和 Milligard® PES 滤器均由 Emprove® 计划提供支持,该计划提供三种类型的文件包,以支持资格确认、风险评估和工艺优化等不同开发及生产阶段的操作。这些文件包以易于获取的格式整合了全面的产品特定测试数据、质量声明和法规信息,助您信心满满地推进工作。
