132542，再生纤维素美国光谱医学SPECTRUMLABS即用型透析袋，S/P 6 50kD 28mm 33英尺，Standard Grade Dialysis Membranes

标准等级再生纤维素（RC）由从棉毛纤维提取的天然纤维素构成，可广泛应用于实验室透析。这种透明、柔韧的膜孔径均一且低廉、结实，非常适用于脱盐、缓冲液置换、大分子纯化及其他一般应用。由于具有广泛的化学相容性，标准RC膜能够与稀强酸碱液、高浓度的弱酸和弱碱、大多数醇类及一些温和的或低浓度有机溶剂（包括DMSO）共用，但与一些强有机溶剂接触可能会破坏RC膜，标准RC膜能够在pH2-12和4-121℃条件下

Spectra/Por 6-7 标准级再生纤维素透析膜（预湿 & 预处理卷装）

Spectra/Por 6透析膜采用预湿型即用包装，使用前无需浸漂去除甘油；Spectra/Por 7透析膜经预处理工艺进一步优化，zui大限度地降低了重金属和硫化物残留量。两种膜均采用0.05%*湿包装。

 

 

一、透析的定义：

       透析（dialysis）是指物质穿过膜的选择性扩散过程。可用于分离分子量大小不同的溶质，低于膜所截留阈值分子量的物质可扩散穿过膜，高于膜截留阈值分子量的物质则被保留在半透膜的另一侧。

 

二、透析袋：

       透析只需要使用的半透膜即可完成。通常是将半透膜制成袋状，就叫做透析袋。在生物大分子的制备过程中，除盐、除少量有机溶剂、除去生物小分子杂质和浓缩样品等都要用到透析的技术。比如蛋白质和DNA的脱盐浓缩，纳米材料的筛选，中药成分萃取后有机溶剂的去处等。

 

三、透析方法

    透析只需要使用的半透膜即可完成。通常是将半透膜制成袋状，将生物大分子样品溶液置入袋内，将此透析袋浸入水或缓冲液中，样品溶液中的大分子量的生物大分子被截留在袋内，而盐和小分子物质不断扩散透析到袋外，直到袋内外两边的浓度达到平衡为止。保留在透析袋内未透析出的样品溶液称为“保留液”，袋（膜）外的溶液称为“渗出液”或“透析液”。通过多次更换透析液而去除盐和小分子物质。
