Hi all,

Has anyone experienced a problem with Paraplast Xtra over the last 3-4 months?  
We are going crazy with compression problems and have tried all the usual 
solutions (tightening all parts of microtome, changing angles, changing blades, 
servicing microtome) and the problem persists.  This involves all 4 of our 
microtomes to varying degrees and all types of tissue.  The only commonality is 
the paraffin. The tissue itself does not compress, but the paraffin around it 
looks like horizontal stripes.  We use Paraplast Xtra for both infiltrating and 
embedding.
Any suggestions?
