低溫恒溫槽用什么介質?

http://www.sewingmachine-review.com/Admin發布于 關鍵詞:

 低溫恒溫槽也就是我司的DFY低溫恒溫反應浴,下面來詳細說明一下,低溫恒溫槽用什么介質?

1.如果是做低溫實驗,處于零下溫度的時候,槽內要用無水乙醇,乙二醇,甲醇做介質,乙醇純度不夠的情況下要注意一下,會結冰。

2.如果是零上溫度,分為幾種情況:溫度在5~85℃之間,一般建議水作為介質;如果是溫度在85~95℃,一般建議甘油作為介質;當溫度高于95℃的時候,我們就要選用油作為主要的介質,在此不建議用水和甘油是因為,水和甘油超過100℃就會沸騰,介質一旦沸騰就會濺出傷人,所以假如選擇油的時候,一定要注意安全,注意距離和燙傷問題。

3.低溫恒溫槽內不僅僅介質類型十分重要,假如介質的液位也很重要,介質的液位一定要低于槽體邊緣30mm左右,否則通電后會損壞加熱裝置。

以上就是低溫恒溫槽關于介質的說明,有什么更多的建議歡迎多多咨詢和交流,可隨時VX:gykryq668.
