全自動液氮冷凍研磨儀研磨尼龍勺實驗-上海凈信
Source：Shanghai Jingxin
實驗目的：研磨尼龍勺，將樣品研磨層粉末，更好的檢測其成分等一系列實驗。
實驗地點：梅里埃營養科學實驗室
實驗材料和器具：
樣品：尼龍勺
儀器：全自動液氮冷凍研磨儀（上海凈信，JXFSTPRP-II）
耗材：專用適配器，研磨管
試劑：液氮若干
實驗步驟
1.準備好研磨管，將研磨管和研磨球清洗干凈，并滅菌滅酶；
2.將需要研磨的樣品剪成小塊，放入準備好的研磨管中，加入研磨珠。蓋好蓋子；
3.將裝有組織樣品的研磨管放入液氮中，冷凍至不沸騰為止；
4.取出已經冷凍的適配器，把冷凍好的不銹鋼研磨管取出插入適配器中；
5.將適配器裝入凈信研磨儀中；
6.設定好參數，啟動儀器至研磨程序結束，可得到粉末狀樣品。
