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.

whatman定量滤纸无灰滤纸42号滤纸：2.5μm Whatman纤维滤纸中保留颗粒Z细小的中速滤纸。常用于诸如硫酸钡、偏锡酸和碳酸钙沉淀物分析。

Whatman纤维素定量滤纸的详细介绍：
Whatman定量滤纸Grade 40/Grade 41/Grade42/Grade43
Whatman定量滤纸有无灰级定量滤纸、硬化低灰定量滤纸和硬化无灰定量滤纸。无灰级滤纸以高质量的棉绒为原料,在严格控制下生产。这些高纯滤纸是各种重要分析过滤步骤中理想用品。硬化低灰滤纸经强酸处理具有高湿强度和化学抗性。这些滤纸特别适合用于布氏漏斗过滤。其坚韧光滑的表面易于回收沉淀物。硬化无灰滤纸经酸硬化处理，具有高湿强和化学抗性，灰分含量极低。坚韧的表面使这些滤纸适用于各种要求严格的过滤步骤。

Quantitative Filter Papers定量滤纸
Whatman定量滤纸是为重力和仪器分析中样品制备而设计的。他们有3种形式来满足你的特别需求。
无灰级：＜0.005%，非常纯的滤纸鸢，是大多数主要分析过滤过程的理想用纸。
硬化低灰：＜0.015%，级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多数主要过滤过程。

 定量滤纸
Whatmana无灰级（灰分＜0.01%）定量滤纸以高质量的棉绒为原料，在严格控制下生产。这些高纯滤纸是各种重要分析过滤步骤中理想用品。

Grade 40：8μm 常规过滤用无灰滤纸，中等流速和颗粒保留度。用于比重分析，原子吸收分光光度法测定前的溶液的过滤和空气污染的采样。

Grade 41：20-25μm 流速zui快的无灰滤纸，用于诸如氢氧化铝或氢氧化铁的分析过程中。大颗粒或凝胶沉淀物的过滤，并用于空气污染定量分析中快流速测定气态化合物。

Grade 42：2.5μm  Whatman纤维滤纸中保留颗粒zui细小的中速滤纸。常用于诸如硫酸钡、偏锡酸和碳酸钙沉淀物分析。

Grade 43：16μm  中速滤纸，用于食品分析、土壤分析、空气污染监测中样品收集和建筑业、矿产和钢铁业的无机分析。

Grade 44：3μm  无论尺寸大小如何，Grade 44的灰分比本系列其他滤纸都低。采集小颗粒的效率比Grade 42略低，但流速则快些。

Grade 589/1：12-25μm  “黑缎滤纸”-定量分析粗糙沉淀物的标准滤纸，是流速很高的无灰滤纸。用于很多定量标准方法，特别是重力应用（如，食物中灰份含量的测定，或是水泥工业中的Blaine布莱因细微颗粒度测定仪测试）。

Grade 589/2：2-12μm  “白缎滤纸”-中等细小颗粒的无灰标准滤纸，中等流速，应用于多种日常定量分析方法，如泥土中沙子含量的测定，面粉级别的测定或造纸工业中水中悬浮物分析。

Quantitative Filter Papers定量滤纸
Whatman定量滤纸是为重力和仪器分析中样品制备而设计的。他们有3种形式来满足你的特别需求。
无灰级：＜0.005%，非常纯的滤纸鸢，是大多数主要分析过滤过程的理想用纸。
硬化低灰：＜0.015%，级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多数主要过滤过程。

Hardened Low Ash Grades硬化低灰定量滤纸
硬化低灰滤纸（灰分＜0.025%）经强酸处理具有高湿度和化学抗性。这些滤纸特别适用于布氏漏斗过滤。其坚韧光滑的表面易于回收沉淀物。

Grade 50：2.7μm Whatmana滤纸中zui薄的一种，流速慢、颗粒保留性能好。硬化的表面有效地防止了纤维的脱落。

Grade 52：7μm 常规过滤用硬化滤纸，保留能力和流速中等。用于布氏漏斗或Whatman三件套过滤漏斗

Grade 54：20-25μm 用于粗颗粒和凝胶状沉淀物和快速过滤。高温强度适合真空快速抽滤难滤物质。

【简单介绍】

Whatman定性滤纸用于定性分析技术中鉴定样品的性质。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。 湿强定性滤纸含有少量的化学稳定树脂，因而增强了湿强度。这不会因此引入任何明显的杂质到滤液中。但因树脂含氮，这些级别的滤纸不能用于凯氏定氮测定。
whatman2号滤纸 1002-090 中速定性滤纸

WHATMAN代理 Grade2定性滤纸中速1002-090，8um，比Grade 1 保留力略强，但过滤时间却相对长些（过滤速度相对慢些），比Grade1吸附型更强。除了8um大小颗粒的普通过滤之外，它额外的吸附性能也拍上了用场，例如在植物生长实验中截留土壤营养物质，监测空气和土壤测试中特殊的污染物等，预折叠的型号是Grade 2V。

定性滤纸－标准级
Grade 1：11μm

在日常过滤中zui经常使用的，中等保留力和流速。非常广泛地用于实验室应用，澄清液体。典型地用于沉淀物的定量分析分离，如硫酸铅，草酸钙和碳酸钙；

比Grade 1保留力略强，但过滤时间却相对长些，吸附性比Grade 1强；

Grade 3：6μm

厚度是Grade 1的两倍。负载力好，颗粒保留较小。由于其湿强度好适合放在布氏漏斗中使用。其高吸附性能可用作为样品的载体；

Grade 4：20－25μm

非常适用于分析中常规生物液体和有机浸出物澄清的快速过滤，空气污染监测中只要求高流速但对细小颗粒收集要求不严的采样；

Grade 5：2.5μm

的定性滤纸，用于收集小颗粒，流速慢。适用于化学分析、澄清悬浮液和水/泥土分析；

Grade 6：3μm

流速是Grade 5的两倍，但颗粒保留度相等。常被制定用于锅炉水分析；

Grade 591：7－12μm

厚滤纸，负载力高，用于中等粗沉淀物的快速过滤，并具有高吸附性和高湿强度，已折叠好的为591 1/2；

Grade 520a：15－18μm

薄滤纸，有很好的湿强度和非常高的流速。通常用于技术应用方面，如粘性液体和乳状液体；

Grade 595：4－7μm

普通的薄滤纸，中等流速，中等颗粒保留力。应用于工业中的许多常规分析，如分离食物提取物中颗粒、制备样品，或者过滤固体环境中可消化样品；

Grade 597：4－7μm

中等流速，中等颗粒保留度。用于不同工业中大量日常分析应用中，如食品测试，或从饲料中去除二氧化碳和混浊物；

Grade 598：8－10μm

厚滤纸，负载力高，对应中等保留力有中等流速和快流速两种流速；

Grade 0048

由纤维素/人工制品制成的纤维纸。用于牛奶分析和婴儿食物中纤维的测定；

Grade 602h：2μm

收集细小颗粒、去除细小沉淀物的紧密滤纸。用于样品制备，如测定饮料行业中残留糖份、酸性光谱、折射分析和HPLC；
