[Histonet] Outdating- Embedding Wax and Mounting Media

[Rene J Buesa]

I think that all the chemical manufacturers (and their representatives) that have been pushing for years this issue of "don't use beyond the shelf life" are feeling like been "caught with their pants down".

How funny! You are so right!!!!!

What about the ink on all of those old reports and reference books? Isn't
ink a 
dye in solvent?

The best special stains I ever did were back in the day when I made my own 
solutions 

from dry chemicals that were already 20 to 30 years old.

Paperwork, just a way to decrease productivity!

  To all Quality Control Purists
There seems to be a growing concern with regards to outdating on reagents
and 
their  continued use beyond this date.  I notice that Histological wax and 
Mounting media are dated with an expiry date. Just begging the
question-should 
we go back. melt down and re-embed all old blocks in fresh wax ?? Should we 
recover slip old slides in fresh dated Mounting media. With all the fuss
over 
quality control in the Laboratory and Government Lab Inspection oversight ,
how 
can this be ignored and our archives put at such dreadful risk ??
