evaporate from the top of the stem to 0.5 ml
is 17 minutes. Adding the two times
together, the total time to evaporate 300 ml
of methylene chloride to 0.5 ml in a sample
tube with a 1.5 ml stem is approximately 76
minutes.
If fewer than eight samples are run at a time,
the time to evaporate will become shorter.
