離心機使用6大注意要點

實驗室常用的是電動離心機電動離心機轉動速度快,玻璃碎片旋轉飛出,造成事故,要注意安全,特別要防止在離心機運轉期間,因不平衡或試管墊老化,而使離心機邊工作邊移動,一致從實驗臺上掉下來,或因蓋子未蓋,離心管因振動而破裂后。因此使用離心機時,必須注意以下操作。

(1)離心管必須對稱放入套管中,防止機身振動,若只有一支樣品管另外一支要用等質量的水代替。

(2)離心機套管底部要墊棉花或試管墊。

(3)啟動離心機時,應蓋上離心機頂蓋后,方可慢慢啟動。

(4)離心時間一般1~2分鐘,在此期間,實驗者不得離開去做別的事。

(5) 電動離心機如有噪音或機身振動時,應立即切斷電源,即時排除故障。

(6)分離結束后,先關閉離心機,在離心機停止轉動后,方可打開離心機蓋,取出樣品,不可用外力強制其停止運動。
