“"When you wake up in the morning, Pooh," said Piglet at last, "what's the first thing you say to yourself?"
"What's for breakfast?" said Pooh. "What do you say, Piglet?"
"I say, I wonder what's going to happen exciting today?" said Piglet.
Pooh nodded thoughtfully.
"It's the same thing," he said.”
When I worked in a lab, we always used a "cold finger" (http://en.wikipedia.org/wiki/Cold_finger) filled with a mixture of dry ice & acetone to condense and freeze any water vapour immediately before the pump to protect the vac pump from water. If not removed, this water can form an emulsion with the oil in the pump and this is not good news. Try removing “butter” from the pump as I had to as a new lab technician when I forgot to put the dry ice in the cold finger…
