Wen,
We use it all the time at 15-20 min. The problem is you have to decrease
the temperature to go that long. You should be able to press the "display"
button until you see SP1 lit up then press the arrow keys for the
appropriate time and/or temperature. You can do this for any of the
settings to optimize for the tissue you are using.
