Hi Paula,

Obviously there are no "compression free" paraffin's on the market.  Look
for a paraffin with a higher polymer content, this makes the paraffin firmer
and less likely to compress.  Other factor for into section compression but
paraffin is a good place to start.

The higher polymer paraffin's are not as suited for processing, it is more
for the embedding portion of the process.

Use a paraffin with lower polymers content in the processor and higher for
embedding and you will like the results.

Hello,



We are considering a switch to a different brand of paraffin and this is
because I feel we are having too many compressions in some of our tissue
sections.  Currently, we use Tissue Path Paraplast, regular.



I would like to get feedback from you as to what you prefer.  Looking on
line, Richard Allan has a product called Signature Series Paraffin that
comes in a type L that offers compression-free sections and I was also
hoping to get any feedback on that product.



I would greatly appreciate any suggestions and thoughts.

Thanks in advance,

Paula
