<strong><span style="font-size:20px;"> 實(shí)驗(yàn)室萬象排氣罩哪種好一點(diǎn)?。?/span></strong><br />
<br />
<span style="font-size:16px;">問：<br />
<span style="color: rgb(69, 69, 69); font-family: 微軟雅黑, 宋體, Arial, Helvetica, sans-serif; line-height: 24px;"> 實(shí)驗(yàn)室萬向排氣罩主要是用來快速排放實(shí)驗(yàn)或生產(chǎn)過程中產(chǎn)生的小范圍的粉塵、熱氣、揮發(fā)性氣體、有害性氣體等小顆粒 狀浮旋物或氣體的裝置，是實(shí)驗(yàn)室里面必不可少的安全設(shè)備。</span><strong></strong>最近，很多實(shí)驗(yàn)室要進(jìn)行一個(gè)整體改造。有人建議在儀器上方安裝那種pp材質(zhì)的萬向罩，有人建議安裝那種固定方口的不銹鋼排氣罩。但是很多人都不知道該選擇哪一種，不知道各有何優(yōu)、缺點(diǎn)？該如何取舍？<br />
<br />
答：<br />
這要看你用在什么地方，如在原子吸收儀上，固定方口的不銹鋼排氣罩好些。<br />
原吸的用不銹鋼的排風(fēng)罩，液相氣相可以用PP萬向罩。<br />
有熱源的比如AA的罩要金屬的，氣相液相自然用PP的；如果是在在AA 上邊安裝萬向罩的建議，那就真的很神奇。</span><br />
