英国Whatman沃特曼Cellulose Nitrate Membrane Circle硝酸纤维素膜介绍
推荐用于大多数日常应用,是在严格控制室内清洁条件下生产的。Whatman膜可以保证非常窄的孔径分布非常低的杂质,这些都可以让最终用户受益。
更高的强度和韧性
大多数膜本质上都很脆而且不容易操作,但是很少在装载到过滤器或在使用过程中损坏。Whatman硝酸纤维素膜韧性得到明显增强,能承受住在不破坏膜完整性的条件下操作、装载和消毒时的撕裂。在同类产品中经测试已经是最强韧的膜。 低可提取物水平
滤膜中可提取物水平和过滤或吸附技术的改进一样变得越来越重要。尤其是在药学、免疫学、生物学组织培养和衡量分析应用方面,高的提取物水平会起到负面影响。Whatman硝酸纤维素膜的提取物水平一般比其他同种型号都低。 精控的孔径分布
Whatman滤膜的一个重要特征就是孔径精确度很高。膜的孔径率径先进的生产和控制系统严格控制。另外批间差小,可以保持实验结果的一致性。 增加的温度稳定性
滤膜可以在不失完整的情况下在121摄氏度下进行正常消毒。硝酸纤维素膜有圆片、方片和卷等不同规格。 收缩量减少
过多的收缩在消毒过程中会产生问题,也经常会在消毒后在滤器中发生破裂,也可能导致流速的降低和整个过滤量的减少。Whatman滤膜在消毒过程中收缩量很低。
特征和优点
·孔径分布精确能改进表面捕获和分析提取物水平低,保证样品的完整性。
应用
·样品分离
·微生物研究
·水溶液过滤
过滤膜类型
白色光滑滤膜
这是大多数实验室应用的标准滤膜,用于1.0um-5.0um大小的颗粒和细胞。
过滤后的残留物大多数保留在膜的表面,可以进行沉淀物物理性回收和显微镜观察。
网格滤膜
有网格的滤膜使得颗粒、微生物、菌落的计数变得容易。如需要网格膜,请查询混合纤维素酯膜。 |
