GE Whatman 沃特曼 混合纤维素膜WME平滑无菌0.45um 47mm
GEWhatman沃特曼混合纤维素膜WME平滑无菌0.45um47mmGEWhatman沃特曼混合纤维素膜WME平滑无菌0.45um47mm,Whatman混合纤维素酯膜由硝酸纤维素膜(NC)和醋酸纤维素(CA)混合制成,它比纯硝酸纤维素膜具有更好的平整性和均匀性,为检测颗粒物和微生物提供了更好的颜色对比,减少了眼睛疲劳。ME型混合纤维滤膜比WME型混合纤维素膜具有更低的醋酸纤维素含量,生物相容性更佳。简化计数过程:在微生物菌落计数过程中,表面同菌落的颜色反差会使得计数过程更加简便。光滑或网格:许多微生物检测法以培养后的菌落计数作为定量标准。Whatman网格滤膜内有间隔3.1mm或者5mm的网格线。用特殊的***性的墨水,并且完全不含***生长的***剂。无菌膜:Whatman提供已包装好的无菌滤膜来提高操作效率,节省了大量时间,且无菌滤膜自带黑色或白***格,方便菌落计数。特征和优点:已消毒了的膜可供主要实验选择非常好的对比,方便颗粒检测网格没***性,也不会******生长,保证样品的完整性黑色平滑或者黑***格膜中混合了硝酸纤维素和醋酸纤维素膜提供了高的内表面积,适合吸附力更高的产品更高的灰尘负载力生物学惰性,良好的热稳定性不含表面活性剂,不会污染样品膜均匀的微孔结构提高了流速热稳定性Whatman黑色混酯膜中光滑型用于自动***计数,而网格型则用于人工计数。黑膜使的残留物或者细胞颜色和膜之间颜色有差异,从而不必对膜进行染色处理。应用Whatman混合纤维素膜在要求更高流速和更大过滤容量的应用中非常有效,包括了水溶液的澄清和消毒、分析和去除颗粒、空气监测和微生物分析,其他应用包括:水溶液的澄清或冷灭菌细胞学空气监测HPLC样品制备(水相)病毒浓缩颗粒物分析生物检测食品微生物包括E.coli计数***生物学研究液体颗粒物计数或气溶胶观察酵母和霉菌技术参数-混合纤维素酯膜普通爆裂强度>10psi重量4.3-5.0mg/cm平方操作温度130℃孔率74-77%蒸汽高压灭菌是抗溶剂中等蛋白吸附率中等产品选择-混合纤维素酯膜膜型号孔径(um)厚度(um)水流速空气流速△p=3mbar(bar)(s/100ml)起泡点(psi)起泡点(bar)WME混合纤维素酯膜-140----ME混合纤维素酯膜ME240.213520-53.653.7ME250.4514512.5-40.62.8ME260.6135482127.551.9ME270.81402.811.618.851.3ME281.214029.311.60.8ME2931501.26.710.150.7订货信息-混合纤维素酯膜(大张卷膜)目录孔径(um)颜色描述数量/包104016050.45白色ME250.45um300mm*100m(宽*长)1104097020.45黑色ME25/30.45um300mm*100m(宽*长)订购信息:尺寸(mm)孔径(mm)目录号描述数量/包ME系列--ME24,平坦无网格250.210401706平滑100pk470.210401712平滑100pk470.210401770平滑,(已灭菌,无菌包装)100pk500.210401714平滑100pk500.210401772平滑,(已灭菌,无菌包装)100pk1000.210401721平滑50pk1100.210401726平滑50pk1420.210401731平滑25pkME系列--ME25,平坦无网格250.4510401606平滑100pk470.4510401612平滑100pk470.4510401670平滑,(已***,无菌包装)100pk500.4510401614平滑100pk500.4510401662无衬纸100pk500.4510401672平滑,(已***,无菌包装)100pk900.4510401618平滑50pk1000.4510401621平滑50pk1100.4510401626平滑50pk1420.4510401631平滑25pkME系列--ME26,平坦无网格250.610401506平滑100pk470.610401512平滑100pk500.610401514平滑100pkME系列--ME27,平坦无网格250.810400906平滑100pk370.810400909平滑100pk470.810400912平滑100pk500.810400914平滑100pk1000.810400921平滑50pkME系列--ME28,平坦无网格251.210400806平滑100pk471.210400812平滑100pk501.210400814平滑100pk1001.210400821平滑50pkME系列--ME29,带网格25310400706平滑100pk47310400712平滑100pk50310400714平滑100pk50310400772平滑,(已***,无菌包装)100pkME系列--ME24,带网格470.210406970白色/黑***格3.1mm,无菌100pk500.210406972白色/黑***格3.1mm,无菌100pkME系列--ME25,带网格470.4510406812白色/黑***格3.1mm100pk470.4510407970白色/黑***格3.1mm,无菌100pk470.4510406871白色/黑***格3.1mm,无菌1000pk470.4510406512白色/黑***格5mm100pk470.4510409770黑色/白***格3.1mm,无菌100pk470.4510409771黑色/白***格3.1mm,无菌1000pk470.4510409414绿色/黑***格3.1mm1000pk500.4510406814白色/黑***格3.1mm100pk500.4510406862白色/黑***格3.1mm,无衬纸100pk500.4510406514白色/黑***格5mm100pk500.4510406572白色/黑***格5mm,无菌100pk500.4510406562白色/黑***格5mm,无衬纸100pk500.4510409714白色/黑***格3.1mm100pk500.4510409772白色/黑***格3.1mm,无菌100pk500.4510409462绿色/黑***格5mm,无衬纸100pk470.4510406800精品膜系列,白色/黑网格3.1mm无菌100pk500.4510406801精品膜系列,白色/黑网格3.1mm无菌100pk500.4510406802精品膜系列,白色/黑网格3.1mm无菌400pk470.4510406803精品膜系列,白色/黑网格3.1mm无菌400pkME系列--ME26,带网格500.610409814黑色/白***格grid3.1mm100pkME系列--ME27,带网格470.810408970白色/黑***格3.1mm,无菌100pk470.810409970白色/黑***格3.1mmwithpad,无菌100pk470.810409270黑色/白***格3.1mm,无菌100pk500.810405672绿色/黑***格3.1mm,无菌100pkME系列--ME28,带网格501.210408472绿色/黑***格3.1mm,无菌100pkWME系列--带网格250.457141-002白色/黑***格3.1mm100pk250.87148-002白色/黑***格3.1mm100pk470.457140-104光滑,无菌100pk470.27187-114白色/黑***格3.1mm100pk470.457141-004白色/黑***格3.1mm100pk470.457141-104白色/黑***格3.1mm,无菌100pk470.457141-114白色/黑***格3.1mm,无菌,无垫片100pk470.457141-124白色/黑***格3.1mm,无菌200pk470.457141-154白色/黑***格3.1mm,无菌,无垫片1000pk470.457141-204白色/黑***格3.1mm,高压无菌包,无菌100pk470.457153-104黑色/白***格3.1mm,无菌)
