RE: [Histonet] Humidity levels in the lab

From:"Burton, Lynn"

In the summertime ours is at around 60-70%, which seems to work well.  
In the winter time it is less than 0 and I run a humidifier full out  
to try to achieve 20%. It is definitely easier in the summer.

I can't offer you any references, but here's something to consider.  A
cool mist humidifier in your lab.  We are in Bend, OR., on the dry side
of the Cascades.  Running the humidifier reduces static and makes
sectioning a bit easier.  No hard science with this, just a little more
atmospheric moisture.
By the way, the humidifier I bought is a big blue and white penguin.
The mist streams out the beak.  Just looking at it makes you smile.  I
bought it at Target for ~ $40.00 - it works for us.
Have a good weekend.

We just moved to a new lab space in a new building. We are currently
running at 45% or lower humidity. I am working with our facilities on
raising the level but I am looking for some references for what level we
should aim for in regard to paraffin cutting. Does anyone have some
ideas or places to look for information?
