Friday afternoon lab fail. The aspirator jar was being cleaned out and rendering one of the tissue hoods unusable. I thought I'd be proactive, clean out the jar and connect it back up to the aspirator. All seemed well despite some confusion over the double jar system. Got a plate of cells out and went to remove the media only for the damn thing to turn into a mass of bubbles. Culture ruined!
I guess I could have tried to work out how to get it to suck but when this kind of thing happens at this time on a Friday, the best option is to say "F@%k it" and avoid any further disasters. I did at least take the aspirator apart so others wouldn't be victim to it's anti-aspirating behaviour.
