實(shi)(shi)驗(yan)(yan)(yan)室中(zhong)安(an)(an)裝通(tong)風柜無疑安(an)(an)裝在(zai)(zai)通(tong)風口就行了(le)，其實(shi)(shi)這(zhe)是(shi)(shi)一(yi)個錯誤的(de)觀點，即使(shi)說通(tong)風柜唯(wei)一(yi)的(de)用(yong)處就是(shi)(shi)排除實(shi)(shi)驗(yan)(yan)(yan)臺上(shang)的(de)氣體(ti)，而且(qie)占(zhan)地(di)(di)面積也(ye)不大，許多(duo)人都習(xi)慣的(de)將通(tong)風柜安(an)(an)裝在(zai)(zai)墻角，離(li)實(shi)(shi)驗(yan)(yan)(yan)的(de)地(di)(di)方遠(yuan)遠(yuan)的(de)，而且(qie)這(zhe)樣不占(zhan)據空間，我(wo)們要(yao)改掉這(zhe)種習(xi)慣，實(shi)(shi)驗(yan)(yan)(yan)室之既(ji)然安(an)(an)裝了(le)通(tong)風柜，我(wo)們一(yi)定要(yao)將其放在(zai)(zai)離(li)實(shi)(shi)驗(yan)(yan)(yan)臺最近的(de)地(di)(di)方。

　　通(tong)風(feng)(feng)設備(bei)不同(tong)于其(qi)它你在實(shi)(shi)驗室中使用(yong)的設備(bei)。不管是水龍(long)頭還是消(xiao)毒(du)柜，放(fang)遠(yuan)一點也(ye)只要(yao)走幾(ji)步就(jiu)能(neng)用(yong)到，充(chong)其(qi)量也(ye)就(jiu)是麻煩一點。但(dan)你如果(guo)把通(tong)風(feng)(feng)裝(zhuang)置(zhi)放(fang)的遠(yuan)遠(yuan)的，當實(shi)(shi)驗過程中排出有(you)毒(du)氣(qi)體時，通(tong)風(feng)(feng)裝(zhuang)置(zhi)就(jiu)不能(neng)即使進行空(kong)氣(qi)的轉換(huan)和流通(tong)。那么即使是再好的通(tong)風(feng)(feng)設備(bei)，也(ye)起(qi)不了多少效果(guo)。

　　通(tong)常情況下，應該把(ba)通(tong)風裝置(zhi)(zhi)安置(zhi)(zhi)在最靠近實(shi)驗臺的位置(zhi)(zhi)，因(yin)為每一(yi)次有毒氣體或粉塵的產生都是從實(shi)驗臺上傳出來的。
