spectrumlabs透析袋(截留分子量50000)標(biāo)準(zhǔn)級(jí)再生纖維素(RC)膜采用經(jīng)再生處理的天然棉絨纖維制成,膜透明,柔韌,性能穩(wěn)定,孔徑精確,是實(shí)驗(yàn)室常規(guī)脫鹽,換液以及大分子純化等透析處理的理想選擇,標(biāo)準(zhǔn)級(jí)RC膜具有良好的化學(xué)耐受性,可耐受低濃度的強(qiáng)酸堿溶液,高濃度的弱酸堿溶液,醇及溫和有機(jī)溶劑,包括DMSO。長(zhǎng)時(shí)間接觸強(qiáng)有機(jī)溶劑可能造成膜損壞。標(biāo)準(zhǔn)級(jí)RC膜適用HP范圍為2-12,適用溫度范圍為4-121 °C。標(biāo)準(zhǔn)級(jí)RC膜僅含有極低水平的重金屬雜質(zhì),一般不會(huì)影響實(shí)驗(yàn)結(jié)果,如實(shí)驗(yàn)樣品較為敏感,可使用重金屬漂洗液于使用前進(jìn)行預(yù)處理。
生物學(xué)惰性和超純的生物技術(shù)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(shù)CE膜對(duì)于嚴(yán)苛環(huán)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(qiáng)酸堿以及低濃度的醇溶液。強(qiáng)有機(jī)溶劑可能導(dǎo)致膜孔徑變化。生物技術(shù)CE膜耐受pH值2-9以及溫度4-37 °C之間。
標(biāo)準(zhǔn)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(jí)別,濕型,浸泡在0.05%疊氮鈉防腐儲(chǔ)存液中,即用型,不需預(yù)處理,標(biāo)準(zhǔn)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(chǎn)品包含0.1%溶液(Supplied wet in 0.1% sodium azide preservative solution
產(chǎn)品特點(diǎn):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
