Membra-Fil混酯膜
Whatman混合纖維素酯膜是由20%的醋酸纖維素和80%的硝酸纖維素組成。與純硝酸纖維素膜相比,這種膜的表面更加光滑和均勻,而且為顆粒檢驗(yàn)提供了良好的顏色對(duì)比,將眼睛疲勞減至z小程度。
 
光滑或網(wǎng)格
許多微生物技術(shù)包括培養(yǎng)后的克隆計(jì)數(shù)作為定量的標(biāo)準(zhǔn)方法。Whatman網(wǎng)格濾膜內(nèi)有間隔3.1mm的網(wǎng)格線。墨水是無毒,并且*不含有細(xì)菌生長的抑制劑。
Whatman黑色混酯膜中,平滑型的用于自動(dòng)克隆計(jì)數(shù)應(yīng)用,而網(wǎng)格的則用于人工計(jì)數(shù)。黑膜使得殘留物或細(xì)胞顏色和膜之間顏色有差異,不必對(duì)膜做染色處理。
 
無菌膜
對(duì)于那些選擇使用通過消毒的滅菌了的膜的微生物工作,Whatman提供用于實(shí)驗(yàn)消毒的黑S網(wǎng)格膜,包括附有墊片。
 
特征和優(yōu)點(diǎn):
有消毒了的膜可供主要實(shí)驗(yàn)選擇;
非常好的對(duì)比,方便顆粒探測;
網(wǎng)格沒有毒性,也不會(huì)抑制細(xì)菌生長,保證樣品的完整性;
消毒后可重復(fù)使用;
黑色平滑或黑S網(wǎng)格膜中硝酸纖維素和醋酸纖維素的比例為80:20;
膜具有高內(nèi)部面積適合吸附力高的樣品;
更高的灰塵負(fù)載力;
低蛋白吸附特性;
生物學(xué)惰性,好的熱穩(wěn)定性;
沒有表面活性劑污染樣品;
膜均勻的微孔結(jié)構(gòu)提高了流速;
熱穩(wěn)定性.
 
應(yīng)用:
這個(gè)膜在要求更高流速和更大過濾容量的應(yīng)用中非常有效,包括水溶液的澄清或消毒,分析和去除顆粒,空氣監(jiān)測和微生物分析,其他應(yīng)用包括:
水溶液的澄清或消毒
細(xì)胞學(xué)
空氣監(jiān)測
HPLC樣品制備(水樣)
病毒濃縮
顆粒分析
微生物分析
食品行業(yè)中,食物微生物學(xué)包括E.coil計(jì)數(shù)
細(xì)菌生物學(xué)研究
液態(tài)和氣態(tài)顆粒計(jì)數(shù)
酵母和霉菌
