Nalgene 250mL一次性過濾器,PES膜,0.2um孔徑,50mm 產(chǎn)品介紹: Thermo Scientific* Nalgene 高流速結(jié)合PES(聚砜醚)膜過濾裝置,PES膜是避免細(xì)胞培養(yǎng)污染的zui后一道防線。PES具備低蛋白質(zhì)粘合性,低萃取物,無外部潤濕劑特點(diǎn),是細(xì)胞培養(yǎng) 基、血清、添加劑和緩沖液無菌過濾的*選擇。不對(duì)稱性PES膜和高速支撐盤能夠提供高流速和高通量,提高過濾效率。250mL容量過濾裝置可以* 滿足生物制藥行業(yè)的無菌要求。上部和接收器都標(biāo)有刻度。側(cè)臂有纖維孔塞和快速拆卸的管道接頭。藍(lán)色套環(huán)。接收器上配有配有防漏旋紋。 Nalgene 250mL一次性過濾器,PES膜,0.2um孔徑,50mm 過濾器類產(chǎn)品:一次性過濾裝置;瓶頂過濾器;針頭過濾器均具有以下特征: » 濾膜為:聚砜醚(PES),通用組織培養(yǎng)濾膜 » 過濾流速快,固有的親水性 » 蛋白質(zhì)粘合性zui低,無外部潤濕劑/表面活性劑--低萃取物 » 250mL過濾裝置的0.2µm 孔徑能夠有效防止細(xì)菌污染 » 同纖維素(醋酸纖維素、硝酸纖維素)濾膜相比具有更佳的耐化學(xué)性 » 無細(xì)胞毒素,無熱原 » 已經(jīng)輻射消毒,NALGENE認(rèn)證 » 過濾產(chǎn)品無菌質(zhì)保藏為5年 產(chǎn)品英文簡介: Thermo Scientific* Nalgene Rapid-Flow disposable Filter Units with PES (polyethersulfone) membrane provide the last line of defense against cell culture contamination. Low protein binding PES membranes with low extractables are the best choice for sterile filtration of cell culture media, serum, additives and buffers. Asymmetric PES membranes and exclusive Rapid-Flow support plate design provide fast flow rates and high throughput for increased filtration efficiency. • Filter cup unscrews from storage bottle for easy access to filtrate • Leakproof (except 115 mL sizes) screw cap closure eliminates pH shift in storage bottle for longer life of stored media • Upper chamber of filter units is clearly marked with pore size, membrane type, catalog number, lot number and expiration date (except 115 mL size) • Padless membrane support minimizes foaming of proteinaceous samples • Non-pyrogenic and non-cytotoxic • PES membrane with blue collar • Gamma radiation-sterilized and individually bagged for a 5-year sterile shelf life 產(chǎn)品性能和應(yīng)用選擇: 性能 » 濾膜越寬,意味著流速越快。在所有的四類濾膜中,僅在500mL和1L的NALGENE系列 產(chǎn)品上采用了75mm直徑的濾膜 » 針對(duì)難于過濾的溶液,我們還可以提供配備90mm直徑濾膜的過濾器 根據(jù)應(yīng)用選擇*濾膜 » PES(聚醚砜)-藍(lán)色套環(huán)。*的細(xì)胞和組織培養(yǎng)基濾膜。低蛋白質(zhì)粘合性,低萃取物,無外部潤濕劑,流速快 » SFCA(無表面活性劑醋酸纖維素)-黃色套環(huán)。比標(biāo)準(zhǔn)醋酸纖維素更清潔。低蛋白質(zhì)粘合性,無潤濕劑。為NALGENE產(chǎn)品所* » CN(硝酸纖維素)-綠色套環(huán)。用于緩沖液和溶液一般過濾的標(biāo)準(zhǔn)濾膜 » NYL(尼龍)-紅色套環(huán)。具有特殊應(yīng)用。無潤濕劑。萃取物降到zui低。*的耐酒精性 » 每一批的MF75過濾裝置、瓶頸和接收器都通過了NALGENE認(rèn)證。每箱中都有一份證明文件,以證明該產(chǎn)品是無菌、無熱原、無細(xì)胞毒素,并且經(jīng)過了嚴(yán)格的性能完整性試驗(yàn) » 所有過濾產(chǎn)品無菌質(zhì)保藏為5年 |
