Sterilizing
This is high pressure steam sterilizer, which I have to use in sterilizing during the biology class. This one seemed better than ours in SCAU microbiology lab. Next time I must write down where they came from and how long have they served. The shape and the color are terrible, and the method of using they are also out of date. The way you operate most of them is a manual work, at first you should control when to deflate that’s because we must sure the air in the sterilizer have gone and there’s only vapor inside, in this way, we can make the temperature in 0.105MPa is 121℃, and just in this temperature the microbe would die.
This morning, our teacher asked my partner to look after the sterilizer and service for all classmates. I don’t know why the teacher ask nobody but her to finish such kinds of mission, maybe our teacher really hope all the people in his class can earn something useful after that. However, my partner went to search her information about her searching class, and I became the one beyond the sterilizer and worked for my class. I’d happy to do that, yet, maybe I have done a wrong thing, for I robbed the opportunity of others which they would reap something. Maybe sterilizing with that antique was very boring, nevertheless, it control the result of all the experiment. Though doing this seems waste of our time, and if nobody did it how our experiment could continue. I don’t think I could be careless in this process, in hence, I did this thing again and again.
Some of my classmates don’t like microbiology experiment, but can anyone tell me what’s wrong with it? Why can’t they enjoy when they have a good teacher? I have the same feeling just as the essay I have written yesterday about my chemistry teacher in middle school.
I am not the God, and even though I’m the God I can’t control the feeling of others. They have their freedom to decide what their favor is, the only thing I could do was give them some suggestion. Why not enjoy the experiment, though some processes of them are really boring. In my opinion, once the first step you walk on the road of science, you should know clearly that you should have preparation for doing some boring thing and repeat the same step again and again with no result.
Now, I have been ready!
