英国Whatman沃特曼Cyclopore膜 

产品介绍:
Whatman聚碳酸脂膜和聚脂膜是孔径可靠的微孔膜,与已有的径迹蚀刻膜相比,可以得到非常准确、重复性好的结果。膜光滑平整,可以确保颗粒保留在膜表面,很容易用显微镜观察到。它是用专利技术生产的,微孔分布非常均匀,由纯净聚合薄膜制成,具有极高的化学均一性。该膜是亲水性的,可与大多数有机溶剂、氨化物和卤化碳氢化合物相容。黑色聚碳酸脂膜背景反差大,能增强分析灵敏度,用于荧光和其它显微镜法最佳。

Membra-Fil混酯膜
Whatman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,而且为颗粒检验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,并且完全不含有细菌生长的抑制剂。
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,不必对膜做染色处理。
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,包括附有垫片。
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;
热稳定性.
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
颗粒分析
微生物分析
食品行业中,食物微生物学包括E.coil计数
