產品介紹：
該設備是制取高純試劑和高純水用的全封閉石英玻璃儀器，它具有技術先進、結構新穎美觀，安裝操作維修簡便的特點。其原理是利用輻射原理保持水溫低于沸點蒸發(fā)冷凝而制取高純水和提取高純試劑。適合實驗制備二次蒸餾水之用。該材料全部采用優(yōu)質石英玻璃制成。蒸餾的水不與任何金屬相接觸。因此純水質量較好。
工作原理
石英亞沸蒸餾是利用熱輻射原理，保持液相溫度低于沸點溫度蒸發(fā)冷凝而制取高純水和高純試劑。
主要特點：
該儀器是用自來水為原水，所產生蒸餾水不與任何金屬接觸，因此水質純度高，完全能滿足之際ppb級分析之用，儀器所用石英玻璃是以含二氧化硅物質，如水晶、硅石、四氧化硅為原料經高溫熔制而成。其二氧化硅含量比普通玻璃高得多，一般石英玻璃二氧化硅含量在99.999%。石英玻璃具有優(yōu)異的耐酸材料，除氫氟和300以上的熱磷酸外，在高溫下，它能耐硫酸，硝酸，鹽酸，王水，中性鹽類，碳和硫等侵蝕，其化學穩(wěn)定性相當于耐酸陶瓷的30倍，相當于鎳鉻合金和陶瓷的150倍，它耐高溫耐熱震，熱膨脹系數(shù)特別小。石英玻璃電學性能，在常溫下，它的電阻，相當于普通玻璃的10-10倍，對全部頻率的介電損失很微小，絕緣耐壓強度大等優(yōu)點。該儀器結構新穎，安裝、操作方便，是國內一家經過改型的產品。

如何安裝石英亞沸蒸餾水器：
1、把石英亞沸蒸餾水器平放在工作臺上（靠近水源及電源），將冷凝器磨砂口一端插入橫式燒瓶的磨砂口上方即。
2、可將溢水口膠管與冷凝水出口膠管引入廢水池；再將冷凝進水膠管與市售自來水管相連；然后把進水膠管與被蒸原水相連，原水進水膠管加裝一止水夾，將冷凝器接口膠管與接受瓶相連即可。
石英亞沸蒸餾水器清洗方式：
1、新出廠的蒸餾器，本廠已清洗好，用戶只需要引入去離子水清洗后直接使用，初次提純水 用以洗滌器皿。
2、長期使用后發(fā)現(xiàn)水質因污染變劣時，可按下列方法清洗。
A、以（Hcl：HNO3=3：1），浸泡24小時。
B、如長期以自來水直接提純結垢污染或因加化學試劑和提純化學試劑而污染時，可在 中浸泡后再以5%HF浸蝕處理，以提純器光亮為準，切勿過度浸泡而變毛，浸蝕后再用去離子水沖干凈，平衡純化。
C、較長時間不用時，可浸泡在2NHNO3中保存。
石英亞沸蒸餾水器是一種容易破碎的貴重儀器，均應輕拿輕放，嚴防劇烈震動和碰撞，以免造成破損。
How to install quartz subboiling distilled water:
1. Place the quartz subboiling distilled water device flat on the working table (close to the water source ａnd power supply), ａnd ｉnsert one end of the frosted mouth of the condenser into the upper part of the frosted mouth of the horizontal flask, i.e.
2. The rubber hose at the overflow ａnd condensate outlet can be introduced into the waste water tank; Then the condensate feed water hose is connected with the market tap water pipe; Then connect the feed water hose with the raw water to be steamed. Add a stop water clamp to the feed water hose ａnd connect the condenser interface hose with the receiving bottle.
Cleaning method of quartz subboiling distilled water:
1, the factory has cleaned the new factory distiller, the user only need to introduce deionized water cleaning directly after use, the first time to extract pure water for washing utensils.
2. If the water quality becomes worse due to pollution after long-term use, the following cleaning methods can be used.
A. Soak for 24 hours with (Hcl: HNO3= 3:1).
B. In case of long-term pollution caused by direct purification ａnd scaling with tap water or pollution caused by addition of chemical reagents ａnd purification chemical reagents, 5%HF etching treatment can be applied after soaking in the water. The light of the purifier shall prevail.
C. When not in use for a long time, it can be soaked in 2NHNO3 for preservation.
Quartz subboiling distilled water is a kind of valuable instrument which is easy to be broken. It should be handled with care to avoid severe vibration ａnd collision, so as not to cause damage.
