[Histonet] Need Some Heat!

The part number is B3120205 and it is called a Para Trimmer...they run
around $500.00.  But honestly, there is no need for scraping blocks if
you embed carefully.  I haven't had to scrape a block (except when I
accidentally tipped one over on the embedding center cooling tray) in

I have a young lady in the same boat, but her employer is doing nothing
about it although the following device has been recommended. She
resorted to embedding so the paraffin amount is just enough to not
create this problem - a tedious way to do it, but it does work - however
others embedding are not so careful.

Go to Thermo Electron and look for their heated paraffin trimmer with
slanted, heated surface and paraffin capture tray. (ParaTrimmer, not
sure of the name)  - it is a bit pricey, but well worth the money and I
would perosnally love to have one in our lab.

You employee's problem may stem from more than just scraping blocks, and
you need to look at other ergonomics involved with her microtomy,
embedding ,etc etc.  Does she operate the  microtome in an ergonomic
manner, have an ergonomic chair, decent setup for reach, forceps that
help her out, all those good things.  Also what she does outside the lab
may be a factor as the young lady here does some other physical
activities (lots of cell phone dialing is one using her thumb to punch
in the numbers) that contributes to her problems in the lab. Hopefully
Jan Minshew, an expert on ergonomics in the histology laboratory can
help you here too.
