We use the paratrimmer too. What we do for a paraffin catcher is to use
a specimen cup (I call them urine cups, but whatever) to catch the
paraffin. When it get fullish, we place in the slide oven to melt the
paraffin, when melted pour off, and reuse the cup... :)

I am looking for a stainless steel knife that we use to scrape off the
paraffin from the embedded blocks. I could not find the 6 inches size
knife in any catalog.
Thanks in advance

In the past, we used an old style permanent edge scalpel blade but after
disaster with one person seirously cutting himself while trimming
from a block, we purchased a Paratrimmer with a heated, slanted metal
surface. This trimmer has made everyone happy by eliminating the
for serious injury and does an even better job of getting rid of excess
There are two models sold, one from Thermo Scientific and the other one
recently spotted on a vendor website. (Sorry, I didn't jot the name
The trimmers are worth the investment to keep you and your employees
from nasty cuts, no matter what the knife/blade, etc could be used.
The only drawback to the Para Trimmer is the messy paraffin drippings
to be collected in some separate container that the manufacturer doesn't
supply. This is more than a bit annoying. It seems to me the
of these devices would design the trimmer with a paraffin catch tray. A
small aluminum baking pan (from grocery store) could be used and
(not a "Green" consideration).
Be safe rather than sorry.
