Quetol 651 is a low viscosity epoxy resin which also acts to some degree as a dehydrating agent and combines chemically in any cured epoxy resin formulation. Both thin and thick sections can be cut without difficulty, and are known for their good stability in the electron beam as well. Some dehydration is needed but one does not have to carry the specimen through to a complete alcohol dehydration. And in addition, one obtains quite acceptable cell preservation at the same time. If you are looking for improved results and have never done it before, Quetol 651 might be a resin system to try out.



Note that the DMP-30 in the formulation has a relatively short shelf life, but, there are precautions one can take to lengthen it, thereby mitigating in some respects that one particular and known disadvantage. 

An understated potential safety risk:
We are addressing now the cured block, something that to most people is about as inert of a material as one will find. But the standard practice in many laboratories is to use a small jeweler's (or even a small hack) saw to cut the block down to the right size, sometimes even to shape it. We want to address the dust that is generated and how its exposure can and should be minimized.
