Re: Paraffin blocks

Dear Andrea,

Paraffin blocks can be stored at room temperature.  There is a block filer from 
Fisher Scientific called HistoPrep Modular File Drawers, cat # 15-182-511.  I 
worked for a hospital were every patient having surgery, received a surgical 
number.  We label our cassettes(blocks) with that surgical number, which was 
filed in numerical order.  There is a pen you can buy through Fisher Scientific 
to write on your cassette blocks.  Also, there is no need to seal your tissues 
with paraffin after it has been cut on.  Yes, we do leave the cut surface of 
the tissue exposed.  In fact, we recut tissues years down the line. The tissue 
comes out just fine.  Good Luck!!

Happy New Year,
