商品详细描述
Whatmana混合纤维素酯膜是由20%的醋酸纤维素和80%的硝酸纤维素组成。与纯硝酸
纤维素膜相比，这种膜的表面更加光滑和均匀，而且为颗粒检测提供了良好的颜色
对比，将眼睛疲劳减至最小程度。
 
光滑或网格
许多微生物技术包括培养后的克隆计数作为定量的标准方法。Whatman网格滤膜内
有间隔3.1mm的网格线。墨水是无毒的，并且完全不含细菌生长的抑制剂 。
Whatman黑色混酯膜中，平滑型的用于自动克隆计数应用，而网格的则用于人工计
数。黑膜使得残留物或细胞颜色和膜之间颜色有差异，不必对膜作染色处理。
 
无菌膜*
对于那些选择使用通过消毒的灭菌了的膜的微生物工作，Whatman提供用于实验消
毒的黑色网格膜，包装附有垫片。
 
特征和优点：*
·有消毒了的膜可供主要实验选择；
·非常好的对比，方便颗粒探测；
·网格没有毒性，也不会抑制细菌生长，保证样品的完整性；
·消毒后可重复使用；
·黑色平滑或黑色网格膜中硝酸纤维素和醋酸纤维素的比例为80∶20；
·膜具有高内部面积适合吸附力高的样品；
·更高的灰尘负载力
·低蛋白吸附特性；
·生物学惰性，好的热稳定性；
·没有表面活性剂污染样品
·膜均匀的微孔结构提高了流速
 
应用：
这个膜在要求更高流速和更大过滤容量的应用中非常有效，包括水溶液的澄清或消
毒、分析和去除颗粒、空气中监测和微生物分析，其他应用包括：
·水溶液的澄清或消毒
·细胞学
·空气监测
·HPLC样品制备（水样）
·病毒浓缩
·微生物分析
·食物行业中，食物微生物学包括E.coil计数
·细菌生物学研究
·液态和气态颗粒计数
·酵母和霉菌
