实验目的:研磨PC材质杯子,将样品研磨层粉末,更好的检测其成分等一系列实验。
实验地点:梅里埃营养科学实验室 。
实验材料和器具:
样品:PC材质杯子
仪器:全自动液氮冷冻研磨仪(上海净信,JXFSTPRP-II)
耗材:专用适配器,研磨管
试剂:液氮若干
实验步骤
1.准备好专用适配器,将研磨管和研磨球清洗干净,并灭菌灭酶;
2.将需要研磨的样品剪成小块,放入准备好的研磨管中,加入研磨珠。盖好盖子;
3.将装有组织样品的研磨管放入液氮中,冷冻至不沸腾为止;
4.取出已经冷冻的适配器,把冷冻好的不锈钢研磨管取出插入适配器中;
5.将适配器装入净信研磨仪中;
6.设定好参数,启动仪器至研磨程序结束,可得到粉末状样品。
