R-1010（10L）旋轉蒸發(fa)儀

R系列(lie)適(shi)用(yong)(yong)于蒸(zheng)(zheng)發、蒸(zheng)(zheng)餾及(ji)分離化(hua)學(xue)品實驗。密封性能顯著；大容量、大口(kou)徑旋(xuan)轉瓶(ping)，蒸(zheng)(zheng)發面積大；置于浴槽中(zhong)，邊旋(xuan)轉邊加熱，配用(yong)(yong)減壓裝置，使溶劑(ji)高效蒸(zheng)(zheng)發。可與(yu)循環水式多用(yong)(yong)真空泵、循環冷(leng)卻器等(deng)組成配套系統(tong)，滿足生產和(he)實驗條件(jian)。

主要用于在減(jian)(jian)(jian)壓條件下連(lian)續(xu)(xu)蒸(zheng)(zheng)餾(liu)大量易揮發(fa)性溶(rong)劑。尤其(qi)對萃取液(ye)的(de)(de)濃縮和色(se)譜分離(li)時(shi)(shi)的(de)(de)接(jie)(jie)收(shou)(shou)液(ye)的(de)(de)蒸(zheng)(zheng)餾(liu)，可(ke)(ke)以分離(li)和純化(hua)反應(ying)產(chan)物。旋轉(zhuan)(zhuan)蒸(zheng)(zheng)發(fa)儀的(de)(de)基本(ben)原理就(jiu)是(shi)減(jian)(jian)(jian)壓蒸(zheng)(zheng)餾(liu)，也就(jiu)是(shi)在減(jian)(jian)(jian)壓情(qing)況下，當(dang)溶(rong)劑蒸(zheng)(zheng)餾(liu)時(shi)(shi)，蒸(zheng)(zheng)餾(liu)燒(shao)(shao)瓶在連(lian)續(xu)(xu)轉(zhuan)(zhuan)動(dong)(dong)。結(jie)構(gou):蒸(zheng)(zheng)餾(liu)燒(shao)(shao)瓶可(ke)(ke)是(shi)一(yi)個帶(dai)有標準(zhun)磨口接(jie)(jie)口的(de)(de)梨形(xing)或圓底(di)燒(shao)(shao)瓶，通(tong)(tong)過一(yi)高度(du)回流(liu)蛇形(xing)冷凝(ning)管與(yu)減(jian)(jian)(jian)壓泵相(xiang)連(lian)，回流(liu)冷凝(ning)管另一(yi)開(kai)口與(yu)帶(dai)有磨口的(de)(de)接(jie)(jie)收(shou)(shou)燒(shao)(shao)瓶相(xiang)連(lian)，用于接(jie)(jie)收(shou)(shou)被蒸(zheng)(zheng)發(fa)的(de)(de)有機溶(rong)劑。在冷凝(ning)管與(yu)減(jian)(jian)(jian)壓泵之(zhi)間有一(yi)三通(tong)(tong)活(huo)塞，當(dang)體(ti)系與(yu)大氣相(xiang)通(tong)(tong)時(shi)(shi)，可(ke)(ke)以將蒸(zheng)(zheng)餾(liu)燒(shao)(shao)瓶，接(jie)(jie)液(ye)燒(shao)(shao)瓶取下，轉(zhuan)(zhuan)移溶(rong)劑，當(dang)體(ti)系與(yu)減(jian)(jian)(jian)壓泵相(xiang)通(tong)(tong)時(shi)(shi)，則體(ti)系應(ying)處于減(jian)(jian)(jian)壓狀態(tai)。使(shi)用時(shi)(shi)，應(ying)先減(jian)(jian)(jian)壓，再開(kai)動(dong)(dong)電動(dong)(dong)機轉(zhuan)(zhuan)動(dong)(dong)蒸(zheng)(zheng)餾(liu)燒(shao)(shao)瓶，結(jie)束時(shi)(shi)，應(ying)先停機，再通(tong)(tong)大氣，以防蒸(zheng)(zheng)餾(liu)燒(shao)(shao)瓶在轉(zhuan)(zhuan)動(dong)(dong)中脫落。作(zuo)為蒸(zheng)(zheng)餾(liu)的(de)(de)熱源，常(chang)配有相(xiang)應(ying)的(de)(de)恒(heng)溫水槽。
