spectrumlabs透析袋(截留分子量50000)標準級再生纖維素(RC)膜采用經再生處理的天然棉絨纖維制成,膜透明,柔韌,性能穩定,孔徑精確,是實驗室常規脫鹽,換液以及大分子純化等透析處理的理想選擇,標準級RC膜具有良好的化學耐受性,可耐受低濃度的強酸堿溶液,高濃度的弱酸堿溶液,醇及溫和有機溶劑,包括DMSO。長時間接觸強有機溶劑可能造成膜損壞。標準級RC膜適用HP范圍為2-12,適用溫度范圍為4-121 °C。標準級RC膜僅含有極低水平的重金屬雜質,一般不會影響實驗結果,如實驗樣品較為敏感,可使用重金屬漂洗液于使用前進行預處理。
生物學惰性和超純的生物技術CE膜提供廣泛的可選孔徑(9種)和尺寸,用于離子分離及大分子純化。3種尺寸中,生物技術CE膜對于嚴苛環境和溶劑條件較為敏感。一般情況下,CE膜可耐受弱酸堿和濃度較低的的強酸堿以及低濃度的醇溶液。強有機溶劑可能導致膜孔徑變化。生物技術CE膜耐受pH值2-9以及溫度4-37 °C之間。
標準RC膜(再生纖維素)透析袋Spectra/Por 6,重金屬離子和硫化物含量為痕跡級別,濕型,浸泡在0.05%疊氮鈉防腐儲存液中,即用型,不需預處理,標準RC膜能適用pH值2-12以及溫度4-121 °C之間。壓平寬有MD10mm直徑6.4mm MD12mm直徑7.5mm MD28mm直徑18mm MD34mm直徑22mm

備注:產品包含0.1%溶液(Supplied wet in 0.1% sodium azide preservative solution
產品特點:An ultra high purity and precise separation dialysis membrance.
1.Hydrophilic and uniform molecular porous dialysis membranes
2.No special chemical precleaning required
提示:The Spectra/Por Biotech CE membranes are sensitive to organic solvents.Solvents such as acetone,MEK or dioxane will irreparably damage it.This membrance will tolerate exposure to lower alcohols(methanol,ethanol,and isopropanol)without apparent damage,but with possible alteration of MWCO,It should not be exposed to organic solvents at concentration exceeding 5% in water
