Whatman是全球过滤系统的标尺,Whatman滤纸以其质量、信赖和一切只为客户的宗旨而著称。为人熟知的Whatman Blue Box是实验室过滤的衡量标准,它拥有多层材料制备的经验和技术,造纸技能已达到了好的水准。
Whatman具备广泛的滤纸生产线,每一种滤纸都有其独特之处,令客户可以根据自己的过滤要求选择优化的滤纸。Whatman使用优质的天然材料,以确保生产的每一张滤纸都保持一贯的质量、可再生性和均一性。每张滤纸在出厂前都经过严格的测试,包括重量、厚度、气体流速和机械强度等方面。此外,个别的参数,比如:颗粒保留、毛细作用率、过滤特征和表观特性等,也可根据需要测定。
标准级定性滤纸
Whatman定性滤纸用于定性分析技术中鉴定物质的性质。折叠好的定性滤纸与相同型号平整的滤纸相比,加快了流速和增加了负载力。
湿强级定性滤纸
这类滤纸非常坚韧,具有比较高的湿强度。普通定性应用中,不会因此引入明显的杂质。需要注意它不能用于凯氏定氮测定等。一些湿强定性滤纸有已折叠好的形式。
无灰级定量滤纸
灰分含量小:Grade 40~44<0.007%,Grade 589<0.01% - 纯的滤纸,是大部分主要分析过滤过程的理想用纸。无灰级硬化定量滤纸
该系列滤纸强度高且具有极低的灰分水平(<0.006%),被誉为世界上zui洁净的分析滤纸,坚韧的表面使,这类滤纸适合于各种严格要求的过滤步骤,每一个级别都兼顾过滤速度和颗粒保留。
低灰级硬化定量滤纸
灰分含量介于无灰滤纸和定性滤纸之间(<0.015%), 经过酸处理去除了微量金属,产生了湿强度和化学抗性,这些滤纸适合用于布氏漏斗,滤纸坚硬的光滑表面使得它很容易回收沉淀物。
