I am going to try to work with plant DNA for the first time. I will be
doing a mortar/pestel grind of leaf tissue under liquid nitrogen, as
specified by the protocol I am following.

My question concerns the mortar and pestel. What is the correct way to
clean the mortar and pestel between grinds so that I don't contaminate
one sample with tissue from another?
