The E. coli plate I spread by myself; grown after 24 hours.
A shaker-incubator. Prof. Goodman said bacteria need to be shaken all the time to get enough oxygen. Why they no get dizzy?I set up a schedule to pick up 6 liquid cultures that would have been induced for different times. Unfortunately, this shaker machine broke (because it was too old and some rubber in it broke) when I was collecting the 12-hour culture. I had to start my experiment all over again next time because I couldn't keep the experimental conditions identical for all 6 cultures. I need some luck for my experiment.
I can still use some of the cells for another experiment. I will determine how many fractions we need to collect from the gravity flow column to obtain the most protein tomorrow.
還好這次實驗還有些用處,不過你的教授不是也說,在實驗室中一天到晚發生這種事情!
ReplyDelete以後你泡茶都要去實驗室拿水嗎?這樣算偷嗎?
泡茶有時候也要做一些小實驗
ReplyDelete首先茶葉的用量要斟酌一下
放少味道不夠太多會苦澀
如果照你描述的應該是放太多茶葉了
水也會有些影響但一般而言差別不會那麼大
即使是硬水煮開也會讓礦物沉澱
水也軟化了
你們實驗室還真的和你指導教授一樣老
我還沒碰過INCUBATOR會破掉的
很好笑耶
當年我同一試驗步驟重複了八九十次
指失敗一次還真的是小意思
不過還是要祝福你GOOD LUCK
The tea wasn't only tasting bitter. It tasted weird when I use the tap water ... and didn't when I use double-distilled water.
DeleteThat happened to you because your professor was no good. He didn't examine what was really going wrong in his lab. It was not only a waste of time for you, also for him.
