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。可用于分離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。
