干式索式提取器 獨立控溫脂肪測定儀主要特征： 1、加熱抽提，溶劑回收和冷卻三大部分組成；

2、抽提時(shi)間可設定，到時(shi)自動停止(zhi)； 

3、采用(yong)金屬加熱塊供熱； 

4、電(dian)路和抽提空間隔(ge)離(li)； 

5、脂(zhi)肪(fang)測定儀操(cao)作時可以根據(ju)試劑沸點和環境(jing)溫度不(bu)同而調節加熱(re)溫度； 

6、大液晶屏微電腦控制，具有超溫報(bao)警功能(neng)； 

7、試樣(yang)在(zai)抽(chou)提(ti)過(guo)程反復(fu)浸(jin)泡及抽(chou)提(ti)，從而達到快(kuai)速(su)提(ti)取目(mu)的；

 8、同(tong)步顯示設(she)定溫(wen)度、實時溫(wen)度、設(she)定時間和加熱計時；

 9、可自動回收(shou)溶(rong)劑，方便用戶使用，節約時(shi)間。
