[Histonet] Formula R paraffin

[Rene J Buesa]

If sometimes you are experiencing compression problems it could be because your paraffin has some xylene contamination, or your blocks are not cold enough when cutting, or you are using a paraffin of lower melting point as needed for the tissue you regularly process.
Paraplast X-tra always worked fine for me. Check with them for a harder paraffin instead of changing to a different paraffin altogether.

Does anyone have any experience with Formula R paraffin, from Leica, good or bad?  We currently use Paraplast X-tra but occasionally have troubles with compression, and we heard Formula R is harder and less likely to compress.



Thanks!
