一、研究原理
因美人蕉纖維含量高,所以實(shí)驗(yàn)人員手工研磨時(shí)間長(zhǎng),而且研磨效果不好,采用上海凈信冷凍研磨儀研磨,方便、快捷、效果好;后續(xù)實(shí)驗(yàn)中主要是為了提取細(xì)胞器!
二、研磨方法
1、實(shí)驗(yàn)步驟:
1,準(zhǔn)備好待研磨的美人蕉樣品鋼罐一套,液氮,清洗并滅菌;
2,將樣品置于鋼罐中,將其整體侵入液氮五分鐘,之后將其并安裝到上海凈信冷凍研磨儀上;
3,設(shè)置頻率,時(shí)間,開機(jī)進(jìn)行研磨;
4,待機(jī)子停止運(yùn)行,取出研磨鋼罐。
5,打開鋼罐往里加提取液手動(dòng)混勻。轉(zhuǎn)移至離心管,轉(zhuǎn)離心幾分鐘;
需了解具體步驟,請(qǐng)致電廠家
