Advice on general occupational hygiene None. Section 8. Exposure controls/personal protection Hand protection Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical products if a risk assessment indicates this is necessary. Considering the parameters specified by the glove manufacturer, check during use that the gloves are still retaining their protective properties. It should be noted that the time to breakthrough for any glove material may be different for different glove manufacturers. In the case of mixtures, consisting of several substances, the protection time of the gloves cannot be accuray estimated. Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid exposure to liquid splashes, mists, gases or dusts. If contact is possible, the following protection should be worn, unless the assessment indicates a higher degree of protection: safety glasses with side-shields. Eye/face protection Environmental exposure controls No special recommendations. Appropriate engineering controls No special ventilation requirements. Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation location.

    滤纸和滤膜

    作为全球过滤系统的标尺,Whatman滤纸以其高质量、可信

    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。拥有创新的多层材料生产方

    面的经验和技术,造纸技能已达到了极高的水准。

    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最优化的滤纸。

    Whatman使用z优质的天然材料,以确保生产的每一张滤纸

    都保持一贯的高质量、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。

    纤维素滤纸

    Whatman纤维素滤纸采用高质量的棉纤维制成,其中α纤维

    素含量达98%以上。纤维素滤纸主要用于普通过滤,截流最

    小颗粒可达2.5μm。Whatman提供多种不同流速的滤纸,以

    满足广大的实验室用户。

    不同型号的滤纸提供不同的纯度、硬度和化学耐受性。

    Grade 2 : 8 μm

    比Grade 1保留力略强,但过滤时间却相对长些(也就是过滤

    速度相对慢些),比Grade1吸附性更强。除了8μm大小颗粒

    的普通过滤之外,它额外的吸附性能也派上了用场,例如在

    植物生长实验中截留土壤营养物质,监测空气和土壤中的特

    殊污染物等,已折叠好的为Grade 2V。

    Whatman定量滤纸

    Whatman定量滤纸是为重量分析和仪器分析中样品制备而设计的。它们有三种形式来满足你的特别需求。
    无灰级:Grade 40~44 <0.007%,Grade 589< 0.01% – 非常纯的滤纸,是大部分主要分析过滤过程的理想用纸。

    硬化低灰:<0.015%, 经过强酸处理去除了微量金属,产生了高的湿强度和化学抗性,这些滤纸特别适合用于布氏漏斗,滤纸坚硬的光滑表面使得它很容易回收沉淀物。

    硬化无灰:<0.006%,非常低的灰分含量,酸硬化增加了湿强度和化学抗性。坚硬的表面使得这些滤纸适合于大多数主要过滤过程。

    Grade 42 : 2.5 μm
    在whatman所有纤维素滤纸中z细的颗粒保留,是重量分析的世界标准。常用于诸如硫酸钡、偏锡酸、碳酸钙、碳酸锶等矿物质的元素含量测定、过滤汽油或有机溶剂,以及光谱和色谱样品的过滤制备,如原子吸收法(AAS)测定饲料中二月桂酸二丁基锡含量测定。
