旋轉蒸發器在購(gou)買的時候應注意什么(me)？

當我(wo)們說起如(ru)何選(xuan)購(gou)旋轉蒸(zheng)發儀，首先我(wo)們看旋轉蒸(zheng)發儀選(xuan)購(gou)的主(zhu)要參數有(you)哪(na)些？

（1）、旋轉蒸發儀容量有這么(me)幾個區分（主(zhu)要針對(dui)國產(chan)產(chan)品）1L、2L、3L、5L、10L、20L、50L

（2）、旋(xuan)轉蒸發(fa)儀(yi)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang)方(fang)式分(fen):手(shou)動(dong)(dong)(dong)(dong)(dong)和自(zi)動(dong)(dong)(dong)(dong)(dong),而(er)自(zi)動(dong)(dong)(dong)(dong)(dong)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang)也(ye)分(fen):水浴鍋(guo)自(zi)動(dong)(dong)(dong)(dong)(dong)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang)和蒸發(fa)瓶(ping)(ping)自(zi)動(dong)(dong)(dong)(dong)(dong)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang),自(zi)動(dong)(dong)(dong)(dong)(dong)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang)主要是針對那些頻繁使(shi)用(yong)的人(ren),自(zi)動(dong)(dong)(dong)(dong)(dong)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang)省力一點,其實,水浴鍋(guo)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang)的好處(chu):可以保護蒸發(fa)瓶(ping)(ping),玻璃軸(zhou)不易(yi)損(sun)壞(huai),而(er)手(shou)動(dong)(dong)(dong)(dong)(dong)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang)從經濟角度來(lai)說,手(shou)動(dong)(dong)(dong)(dong)(dong)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang)比(bi)自(zi)動(dong)(dong)(dong)(dong)(dong)升(sheng)(sheng)(sheng)(sheng)降(jiang)(jiang)來(lai)的實惠

（3）、看密封度(du)(du),也(ye)就是真(zhen)(zhen)空(kong)(kong)度(du)(du)的好(hao)壞(huai),真(zhen)(zhen)空(kong)(kong)度(du)(du)越高蒸發(fa)速度(du)(du)越快,一般真(zhen)(zhen)空(kong)(kong)度(du)(du)可(ke)(ke)以達到0.095mpa,一般2L5L可(ke)(ke)以配(pei)SHB-III循環(huan)水(shui)泵(beng)(beng)而(er)10L以上就要(yao)配(pei)SHB-B循環(huan)水(shui)泵(beng)(beng),真(zhen)(zhen)空(kong)(kong)度(du)(du)好(hao)壞(huai)跟密封圈也(ye)有(you)很大關(guan)系,一般密封圈質量好(hao)一些，會(hui)比較耐腐(fu)蝕(shi),這樣任(ren)何熔劑都不會(hui)影響(xiang)真(zhen)(zhen)空(kong)(kong)泵(beng)(beng).而(er)且使用(yong)壽(shou)命比較長

（4）、其次外(wai)(wai)觀(guan)好(hao)不好(hao)看(kan)也很(hen)重要(yao)，也很(hen)多用戶會(hui)看(kan)外(wai)(wai)表的(de)(de)，這個就要(yao)看(kan)個人的(de)(de)審美(mei)觀(guan)嘍，如果喜歡外(wai)(wai)觀(guan)好(hao)看(kan)的(de)(de)，我(wo)建(jian)意客(ke)戶可以買上海(hai)亞(ya)榮的(de)(de)產品(pin)，整體外(wai)(wai)觀(guan)比較人性化

 現在我們來談談旋轉蒸發儀價格，選購除了看這些參數(shu)也要(yao)參考慮產品的大概價(jia)格，行情是關鍵。所以我要(yao)帶大家了解一下旋轉蒸發儀(yi)的行情及大概的成(cheng)交價(jia)。

 國內一(yi)般(ban)(ban)生產(chan)旋(xuan)轉(zhuan)(zhuan)蒸發儀(yi)(yi)的(de)(de)(de)廠家(jia)肯定(ding)不下80家(jia)，但真正好(hao)的(de)(de)(de)技術基(ji)本上(shang)(shang)(shang)(shang)都集(ji)中在(zai)(zai)(zai)(zai)上(shang)(shang)(shang)(shang)海(hai)，一(yi)般(ban)(ban)上(shang)(shang)(shang)(shang)海(hai)產(chan)的(de)(de)(de)會比外(wai)地(di)產(chan)的(de)(de)(de)來的(de)(de)(de)更好(hao)，無論從外(wai)觀(guan)還(huan)是(shi)從質量上(shang)(shang)(shang)(shang)面。一(yi)般(ban)(ban)上(shang)(shang)(shang)(shang)海(hai)產(chan)的(de)(de)(de)旋(xuan)轉(zhuan)(zhuan)蒸發儀(yi)(yi)2L價格(ge)一(yi)般(ban)(ban)在(zai)(zai)(zai)(zai)3千到4千左(zuo)(zuo)(zuo)右(you)。而3L的(de)(de)(de)旋(xuan)轉(zhuan)(zhuan)蒸發儀(yi)(yi)價格(ge)在(zai)(zai)(zai)(zai)6千多，5L一(yi)般(ban)(ban)也在(zai)(zai)(zai)(zai)8~9千這(zhe)上(shang)(shang)(shang)(shang)下，而10L價格(ge)也是(shi)1萬(wan)(wan)5左(zuo)(zuo)(zuo)右(you)，20L價格(ge)在(zai)(zai)(zai)(zai)2萬(wan)(wan)3左(zuo)(zuo)(zuo)右(you)，50L的(de)(de)(de)價格(ge)也在(zai)(zai)(zai)(zai)3萬(wan)(wan)5左(zuo)(zuo)(zuo)右(you)。以上(shang)(shang)(shang)(shang)這(zhe)些價格(ge)是(shi)含水浴鍋(guo)的(de)(de)(de)價格(ge)。

 以(yi)上基(ji)本上說(shuo)是(shi)(shi)國(guo)產的價格，我們現在說(shuo)說(shuo)進(jin)(jin)(jin)口產品價格，一(yi)般(ban)進(jin)(jin)(jin)口高端產品有竟爭力的兩(liang)家，德(de)國(guo)海(hai)道夫(fu)和瑞士步琪(qi)兩(liang)種品牌，普通(tong)蒸發到4L容量，價格都在4萬(wan)左右(you)，不(bu)過進(jin)(jin)(jin)口產品主要(yao)看(kan)是(shi)(shi)如何配置，一(yi)般(ban)一(yi)套全配好大概價格也要(yao)十幾萬(wan)。還有德(de)國(guo)IKA的旋轉(zhuan)蒸發儀是(shi)(shi)屬于經濟(ji)型的，IKA旋轉(zhuan)蒸發儀的價格在2萬(wan)多元(yuan)。
