[lm-announce] IMPORTANT - heated chambers

[Sam Swift]

Dear All,

A quick note about the heated chambers.  Occasionally some of you  
need to change the temperature of the heated chambers by a few  
degrees, which is fine.  Unfortunately this is not as straightforward  
as you might think because -

1.  the temperature sensor is not accurate; if you set it to 37,  
there is no way it's really going to end up at 37
2.  it takes a long time for the temperature to stabilise

If you need to change the temperature of the chamber please could you  
do the following -

1.  check with us before you do it
2.  check the temperature setting before you start
3.  book an extra hour after your session to allow enough time for  
the temperature to stabilise
4.  check the mercury thermometer inside the chamber to make sure it  
really has returned to 37 before the next person starts

It sounds trivial I know, but we've had too many cases of people  
turning up to do live cell experiments and finding the chamber at  
totally the wrong temperature and wrecking their session.

Thanks,
Sam
