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。它是用技术生产的,微孔分布非常均匀,由纯净聚合薄膜制成,具有*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。
Cellulose Nitrate Membranes 硝酸纤维素膜
推荐用于大多数日常应用,是在严格控制室内清洁的条件下生产的。一般情况下,无须要求任何明显的技术改变,就可以直接换掉其他生产厂的用于一般过滤目的的滤膜。使用者会从Whatman现有的滤膜的改进中获得益处。
更高的强度和韧性
大多数膜本质上都很很脆弱而且不容易操作;但是很少在装载到过滤器或在使用过程中损坏掉。Whatman硝酸纤维素膜韧性很明显加强了,能承受住在不破坏膜完整性的条件下操作、装载和消毒时撕裂。经破裂测试已是zui强的膜。
低可提取水平
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、免役学、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它同种型号的膜低。
孔径精确
Whatman滤膜一个主要特征是孔径精确度很高。膜的孔径率经先进的生产和控制系统严格控制。另外,批间差的变化zui小,保持*的实验结果。
增加的温度稳定性
滤膜可以在不失完整性的情况下在121℃下进行正常消毒。硝酸纤维素滤膜有圆片、方片和卷状等规格。
收缩量减少
过多的收缩在消毒过中会产生问题,也经常会在消毒后在滤器中发生膜的撕裂,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低
特征和优点
- 孔径分布精确改进表面俘获和分析。
- 提取物水平低,保证样品的完整性。
应用
Cellulose Nitrate Filter Types 硝酸纤维素膜类型
白色光滑滤膜
这是大多数实验室应用的标准滤膜,用于1.0µm-5.0µm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显微镜观察。
用于核酸和蛋白分析的硝酸纤维素膜
1975年,E.M.Southern发明了从琼脂胶转移DNA到一张硝酸纤维素的技术。这个技术以它的发明者命名为Southern Blotting随后,蛋白和RNA转移的技术也发展起来了。与层析技术相关的是需要相当数量的高质量的色谱纸,3MM纸已经成为**的层析纸。

产品简介
whatman BA诊断膜是由纯硝酸纤维素构成的无底衬膜。这些小孔径的膜拥有很大的表面积,很高的蛋白吸附量。
渗滤法诊断膜?用来做渗滤测试的膜通常就是覆盖有硝酸纤维素膜的纸。膜直接覆盖在高质量纤维滤纸的表面。简化了生产工艺,降低了不同材质之间接触不良造成的检测问题的可能性,可以使用小孔径的不带衬的膜。当然,他们需要被非常仔细地包裹以保证膜和滤纸之间的紧密结合。
BA诊断膜是由纯硝酸纤维素构成的无底衬膜。这些小孔径的膜拥有很大的表面积,很高的蛋白吸附量。
功能和优点
·为纵向流测试制造 消除由毛细上升引起的问题
·较小的孔径 结果准确,更低的非特异性吸附,更高的灵敏度
·增大的表面积 高结合能力,高灵敏度,得到非常好的信噪比。
·100%纯硝酸纤维素 保证了的吸附能力

Cellulose Nitrate Membranes 硝酸纤维素膜
推荐用于大多数日常应用,是在严格控制室内清洁的条件下生产的。一般情况下,无须要求任何明显的技术改变,就可以直接换掉其他生产厂的用于一般过滤目的的滤膜。使用者会从Whatman现有的滤膜的改进中获得益处。
更高的强度和韧性
大多数膜本质上都很很脆弱而且不容易操作;但是很少在装载到过滤器或在使用过程中损坏掉。Whatman硝酸纤维素膜韧性很明显加强了,能承受住在不破坏膜完整性的条件下操作、装载和消毒时撕裂。经破裂测试已是zui强的膜。
低可提取水平
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、免役学、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它同种型号的膜低。
孔径精确
Whatman滤膜一个主要特征是孔径精确度很高。膜的孔径率经先进的生产和控制系统严格控制。另外,批间差的变化zui小,保持*的实验结果。
增加的温度稳定性
滤膜可以在不失完整性的情况下在121℃下进行正常消毒。硝酸纤维素滤膜有圆片、方片和卷状等规格。
收缩量减少
过多的收缩在消毒过中会产生问题,也经常会在消毒后在滤器中发生膜的撕裂,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低

Cellulose Nitrate Filter Types 硝酸纤维素膜类型
白色光滑滤膜
这是大多数实验室应用的标准滤膜,用于1.0μm-5.0μm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显微镜观察。
用于核酸和蛋白分析的硝酸纤维素膜
1975年,E.M.Southern发明了从琼脂胶转移DNA到一张硝酸纤维素的技术。这个技术以它的发明者命名为Southern Blotting随后,蛋白和RNA转移的技术也发展起来了。与层析技术相关的是需要相当数量的高质量的色谱纸,3MM纸已经成为**的层析纸。
