旋轉(zhuǎn)蒸發(fā)儀使用方法
1.打開低溫冷卻液循環(huán)泵。注意按電源鍵后再按下制冷鍵,降到所需溫度(4℃)。
2.打開水流抽氣機(真空泵)。
3.裝上蒸餾燒瓶并用夾子固定好。待有一定真空后開始旋轉(zhuǎn)。
4.調(diào)節(jié)蒸餾燒瓶高度(手柄置于Free位置可調(diào)節(jié)高度,然后置于Lock鎖定、旋轉(zhuǎn)速度(打開綠色按鈕燈亮,旋轉(zhuǎn)設(shè)定轉(zhuǎn)速),設(shè)定適當水浴溫度(35-40℃)。
5.蒸完先停止旋轉(zhuǎn),打開通氣閥,然后關(guān)閉水流抽氣機,最后再取下蒸餾燒瓶。
6.關(guān)閉低溫冷卻液循環(huán)泵,停水浴加熱,倒出***瓶內(nèi)溶劑,洗干凈緩沖球,***瓶。
