微孔濾膜廣泛應(yīng)用于樣品分析和實(shí)驗(yàn)室樣品過(guò)濾中?；旌侠w維素酯膜（水系濾膜）由硝酸纖維素酯和醋酸纖維素酯制成，是一種多孔性的精密過(guò)濾材料，濾膜表面孔徑分布均。相比較于硝酸纖維膜，其*性和表面的光滑程度都要更好。此類膜經(jīng)典應(yīng)用于溶液中懸浮微粒的粒子計(jì)數(shù)和分析。尼龍膜（有機(jī)系濾膜）材質(zhì)強(qiáng)韌，適用于HPLC中的大部分溶液（如酒精）過(guò)濾，尤其對(duì)氣體凈化和微粒重量分析有獨(dú)到之處。

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.

微孔濾膜技術(shù)參數(shù)：Specification

品名: 水系濾膜，有機(jī)系濾膜

Name: hydrophilic Membrane （water-loving）,hydrophobic Membrane （water-hating）

材質(zhì): 混合纖維素酯，尼龍

Materials：Mixed cellulose ester,nylon

公稱孔徑Pore size：0.22um，0.45um，0.8um.

直徑Diameter：13mm，25mm，47mm，50mm，100mm，150mm

選膜小建議：Suggestion

1.判斷微粒的大小是被保留還是被過(guò)濾。濾膜將保留所有直徑大于或等于公稱直徑的粒子。

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

2.估計(jì)要過(guò)濾的液體或氣體與濾膜在化學(xué)性質(zhì)方面能否共存。判斷出將過(guò)濾的各種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.還要考慮選擇水系還是有機(jī)系濾膜，溫度，流速，和是否需滅菌等因素。

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