M N 微孔滤膜

微孔滤膜广泛应用于样品分析和实验室样品过滤中。混合纤维素酯膜（水系滤膜）由硝酸纤维素酯和醋酸纤维素酯制成，是一种多孔性的精密过滤材料，滤膜表面孔径分布均。相比较于硝酸纤维膜，其*性和表面的光滑程度都要更好。此类膜经典应用于溶液中悬浮微粒的粒子计数和分析。尼龙膜（有机系滤膜）材质强韧，适用于HPLC中的大部分溶液（如酒精）过滤，尤其对气体净化和微粒重量分析有独到之处。

Membrane is widely used in analyticallaboratory filtration. Mixed cellulose ester membranefor hydrophilic is a mixture of cellulose acetatecellulose nitrate. It is a porous delicate filtering materialthe pore evenly distribute on the membrane surface, provides a more uniformsmoother surface compared to pure nitrocellulose membrane. This membrane is typically used toor analyze particles contained in liquids or captured from aerosols. Nylon membranefor hydrophobic is strongcompatible with a broad range of aqueous solution including alcoholssolvents used in HPLC work. It is suitable for air decontaminationparticles analyze.

选膜小建议：Suggestion

1.判断微粒的大小是被保留还是被过滤。滤膜将保留所有直径大于或等于公称直径的粒子。

Determine the particle size to be retained or filtered. Membranes will retain all praticles equal to,larger than their designated pore size.

2.估计要过滤的液体或气体与滤膜在化学性质方面能否共存。判断出将过滤的各种溶液混合后是否能共存。

Assess the chemical compatibility of the membrane filter with the liquid or gas to be filtered. Consider the chemical resistance properties of all the parts that will contact the filtrater.

3.还要考虑选择水系还是有机系滤膜，温度，流速，和是否需灭菌等因素。

Also consider hydrophilic or hydrophobic membranes, temperautre, flow rate,sterilization needs.
