This weekend, I had a DNA prep in the ultracentrifuge. My entire Monday schedule was predicated on the success of this run, and frankly so was the rest of my week. Well, I came in Monday morning to find the ultra sitting there quietly, power switch in the Off position. It turns out the power switch is also a circuit breaker, and something terrible had occurred, causing the ultra to politely turn itself off. On consulting with my lab mates, it turns out our other ultra exploded this weekend (not in a spectacular or dangerous way, more in a smelly, burning way). So I call the service guy to come out and take a look at both our centrifuges ASAP.
And it turns out the only other ultracentrifuge in the building: also broken.
Good one, God.
