、請切記空載（一定要將超聲變幅桿插入樣品后才能開機,） 2、變幅桿（超聲探頭）入水深度： 1.5Cm 左右，液面高度比較好有30mm以上，探頭要居中，不要貼壁。超聲波是垂直縱波，插入太深不容易形成對流，影響破碎效率。 3、超聲參數設置：設置鍵好儀器工作參數，對于對溫度要求比較敏感的樣品（比如細菌）一般外面采用冰浴，實際溫度肯定是低于25度，蛋白核酸肯定不會變性。 1）時間：超聲時間每次比較好不要超過5秒，間隙時間應大于或等于超聲時間，以便于熱量散發(fā)。時間設定應以超聲時間短，超聲次數多原則，可延長超聲機子以及探頭的壽命。 2）超聲功率：不宜太大，以免樣品飛濺或起泡沫，如小于10ml樣品容量，功率應在200w以內,選用2mm超聲探頭，另將面板后面的變幅桿選擇開關打到相應擋；10-200ml樣品容量的功率在200－400w，選用6mm超聲探頭，另將面板后面的變幅桿打到相應擋；200ml以上的樣品容量功率在300-600w之間，選用10mm超聲探頭，另將面板后面的變幅桿打到相應擋；（2MM的小探頭功率嚴禁超過350W） 3）容器選擇：有多少的樣品就選多大的燒杯，這樣也是有利樣品在超聲中對流，提高破碎效率山東通用冷凍干燥機價格</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北京控溫冷凍干燥機全國發(fā)貨,冷凍干燥機"
