一、 <b>产品简介：</b><b></b>
</p>
<p class="MsoNormal">
<b>酸纯化仪</b>：又称酸纯化系统，高纯酸提纯器，酸试剂提纯器，高纯酸蒸馏纯化器等，<span>实验室工作中常常由于酸的纯度较差，造成分析结果的偏差与错误。市售的超纯酸往往由于价格较贵，很难满足日常分析中对酸的大量需求。因此，提纯优化酸的质量，为经济可行的途径</span>，我厂的酸纯化器<span>可用于实验室如</span>HNO3、HCl、HF<span>、碱溶液和有机溶剂的纯化，</span><b><span>纯化后的酸和</span>Merck的一样好</b><span>，</span><span>实验后期可配套我单位</span>Teflon特氟龙系列试剂瓶收取高纯酸。
</p>
<p class="MsoNormal">
<b>二、工作原理：</b><b></b>
</p>
<p class="MsoNormal">
<b>酸纯化仪</b>是利用热辐射原理，保持液体温度低于沸点温度蒸发，再将其酸蒸气冷凝从而制备高纯水和高纯试剂，广泛应用于样品处理及分析实验中。
</p>
<p class="MsoNormal">
三、 <b>产品特点：</b><b></b>
</p>
<p class="MsoNormal">
1、可以满足ICP、ICP-MS极低的检测限需要及苛刻的分析应用中提供实验室级超纯酸，所用容器均采用Teflon耐腐蚀无吸附塑料，<span>可处理如</span>HNO3、HCl、HF等实验室的常用酸。
</p>
<p class="MsoNormal">
2、实验证明将金属杂质含量约10ppb的酸经过一次蒸馏后，金属杂质含量可以降低到0.01ppb左右。若对酸要求更高，可增加提纯次数。
