標(biāo)準(zhǔn)等級(jí)再生纖維素（RC）由從棉毛纖維提取的天然纖維素構(gòu)成，可廣泛應(yīng)用于實(shí)驗(yàn)室透析。這種透明、柔韌的膜孔徑均一且低廉、結(jié)實(shí)，非常適用于脫鹽、緩沖液置換、大分子純化及其他一般應(yīng)用。由于具有廣泛的化學(xué)相容性，標(biāo)準(zhǔn)RC膜能夠與稀強(qiáng)酸堿液、高濃度的弱酸和弱堿、大多數(shù)醇類及一些溫和的或低濃度有機(jī)溶劑（包括DMSO）共用，但與一些強(qiáng)有機(jī)溶劑接觸可能會(huì)破壞RC膜，標(biāo)準(zhǔn)RC膜能夠在pH2-12和4-121℃條件下
Spectra/Por 6-7 標(biāo)準(zhǔn)級(jí)再生纖維素透析膜（預(yù)濕 & 預(yù)處理卷裝）
Spectra/Por 6透析膜采用預(yù)濕型即用包裝，使用前無需浸漂去除甘油；Spectra/Por 7透析膜經(jīng)預(yù)處理工藝進(jìn)一步優(yōu)化，zui大限度地降低了重金屬和硫化物殘留量。兩種膜均采用0.05%*濕包裝。
一、透析的定義：
透析（dialysis）是指物質(zhì)穿過膜的選擇性擴(kuò)散過程。可用于分離分子量大小不同的溶質(zhì)，低于膜所截留閾值分子量的物質(zhì)可擴(kuò)散穿過膜，高于膜截留閾值分子量的物質(zhì)則被保留在半透膜的另一側(cè)。
二、透析袋：
透析只需要使用的半透膜即可完成。通常是將半透膜制成袋狀，就叫做透析袋。在生物大分子的制備過程中，除鹽、除少量有機(jī)溶劑、除去生物小分子雜質(zhì)和濃縮樣品等都要用到透析的技術(shù)。比如蛋白質(zhì)和DNA的脫鹽濃縮，納米材料的篩選，中藥成分萃取后有機(jī)溶劑的去處等。
三、透析方法
透析只需要使用的半透膜即可完成。通常是將半透膜制成袋狀，將生物大分子樣品溶液置入袋內(nèi)，將此透析袋浸入水或緩沖液中，樣品溶液中的大分子量的生物大分子被截留在袋內(nèi)，而鹽和小分子物質(zhì)不斷擴(kuò)散透析到袋外，直到袋內(nèi)外兩邊的濃度達(dá)到平衡為止。保留在透析袋內(nèi)未透析出的樣品溶液稱為“保留液”，袋（膜）外的溶液稱為“滲出液”或“透析液”。通過多次更換透析液而去除鹽和小分子物質(zhì)。
