Heather,If I recall correctly this was discussed on Histonet some time ago, and a large number of folks said their favorite for marking cassettes was the good ol' fashioned #2 lead pencil.  The markings stayed on the cassettes no matter what treatments and reagents were used.This is a separate issue from slide marking, where things get a little more confusing...Quite a few people had good things to say about Secureline marking pens, but I don't recall if the remarks were re: cassettes or slides or both.  The Secureline pens are marketed toward the histology/pathology crowd, and I'm sure they're available from several vendors.  For more info, see for example:Best regards,Bob Robert (Bob) Chiovetti, Ph.D.Southwest Precision InstrumentsArizona's Microscopy Resource132 North Elster DriveTucson, AZ 85710-3212Tel./Fax 520-546-4986Member, Arizona Small Business Association(www.asba.com)----- Original Message ----I would love to hear about a good histo pen for our cassettes.  We are currently having problems with smudging.  What are the best histo resistant pens out there that don't smudge.  We use Tissue Tek cassettes and use your standard processing reagents.  Thank you in advance.Heather Renko ____________________________________________________________________________________Want to start your own business?Learn how on Yahoo!
