Subject: Control stylet


Hi Patsy,
My name is Charmaine Jankowski and I am an IHC Tech from ACL  Lab. in
Milwaukee, Wi. My phone is 414-328-6236.
I am looking for a special tool that you can take a piece of tissue out of a
paraffin block to be used in a multi tissue control block. It's kind of like
a dermal punch, but it is used for Histology only. I only find a cork stylet
in the catalogs and that is not what I want.  If you know where I can
purchase one, I would appreciate you giving me the name and phone number of
the company that makes them.
Thank you,
Charmaine:):):):)
