  The water bath temperature has to be bellow the melting point (MP) of the paraffin. I always had ours at 45ºC and that was what we had in our logs. Not always it was 45ºC, sometimes it deviated 1 or 2ºC and that was acceptable but you should regulate yours according with the MP of the paraffin you use.

  Recently we were cited for not measuring the temperature of our water
baths (tissue floatation baths). We use Richard Allan Type 9 paraffin.
I am trying to put down a range of acceptable temperatures for our daily
quality control. Any ideas?
