132542，再生纖維素美國光譜醫學SPECTRUMLABS即用型透析袋，S/P 6 50kD 28mm 33英尺，Standard Grade Dialysis Membranes
標準等級再生纖維素（RC）由從棉毛纖維提取的天然纖維素構成，可廣泛應用于實驗室透析。這種透明、柔韌的膜孔徑均一且低廉、結實，非常適用于脫鹽、緩沖液置換、大分子純化及其他一般應用。由于具有廣泛的化學相容性，標準RC膜能夠與稀強酸堿液、高濃度的弱酸和弱堿、大多數醇類及一些溫和的或低濃度有機溶劑（包括DMSO）共用，但與一些強有機溶劑接觸可能會破壞RC膜，標準RC膜能夠在pH2-12和4-121℃條件下
Spectra/Por 6-7 標準級再生纖維素透析膜（預濕 & 預處理卷裝）
Spectra/Por 6透析膜采用預濕型即用包裝，使用前無需浸漂去除甘油；Spectra/Por 7透析膜經預處理工藝進一步優化，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）是指物質穿過膜的選擇性擴散過程?？捎糜诜蛛x分子量大小不同的溶質，低于膜所截留閾值分子量的物質可擴散穿過膜，高于膜截留閾值分子量的物質則被保留在半透膜的另一側。
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、除少量有機溶劑、除去生物小分子雜質和濃縮樣品等都要用到透析的技術。比如蛋白質和DNA的脫鹽濃縮，納米材料的篩選，中藥成分萃取后有機溶劑的去處等。
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，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，而鹽和小分子物質不斷擴散透析到袋外，直到袋內外兩邊的濃度達到平衡為止。保留在透析袋內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。
