*whining alert*
This is an extremely tiring week due to all the alternate tutorials, labs and practicals occuring in the same week. I gotta wake up at 0530 from Monday to Thursday, 0730 on Friday and Saturday, and 0630 on Sunday. My school days ends at 1800, 1700, 1600, 1900, 1400. This sucks for a college timetable.
Today saw us having lessons from 0800 to 1700 straight, with only a short period to break for lunch. We had our first super sian seven-hour laboratory session.
I screwed it up. Knew it wasn’t a good sign when jeffrey, xinli and my compound refuse to react under the right conditions, which already made us a lot slower than all the rest.
When we finally got the right compound, we rushed through everything, and all was well until I placed my product’s flask under rotatory evaporator (some machine that rotates a flask clamped onto it and sucks out the solvent.) I forgot to turn on the vacuum and left it alone while I got ready to clean up my fume hood. The next moment I saw my friend running towards me shouting “disaster”. The flask had fallen off the machine’s clamp because the vacuum wasn’t turned on, and all my hard work (chemicals) spilt into the sink!!!
Luckily the TA (who was visibly angry) merely asked me to wash and setup the machine again, and at my request, allowed me to re-do the experiment. The sian thing is, I have to repeat the whole procedure next wednesday, AGAIN!
So bloody tired now but still have so many overdue tutorials and that biochem lecture to watch on webcast today which I had to skip because of the stupid lab. I don’t even want to think of how I am going to repeat this whole damn thing again. lol..
