Work + weather...
It was really hot outside today. Indoors, it wasn't much better. And in lab, this sucks. Anything usually considered volatile is much more volatile when it's hot. Anything that stinks gets really unbearable in days like this. And anything that's reasonably cold is quickly covered with drops of water condensate from air moisture - including stuff that's supposed to be dry, such as the inner wall of reflux condensers.
Are yoru labs not air conditioned? Damn Sounds like hell.
