[Histonet] How to keep cryostating without getting

I cut little rectangular pieces of styrofoam from any of the cartons
that are shipped in with cold or frozen items and "glue" them to each
side of the knife holder with OCT. This provides a great area to rest
my hands while having to manipulate a frozen section. The styrofoam
doesn't get cold and it is a comfty place to put your hands and also
a slide if you have to pick up multiple sections on one slide. The
tissue and OCT doesn't thaw or the slide doesn't get too cold for
another section to attach.
This excellent piece of advice came from Gayle Callis - thank you
PS: When I want to clean out the cryostat I just turn it off and take
out the knife holder and when the OCT warms up the styrofoam comes
off and can be reattached when the cryostat is all clean and ready to
be turned back on.
I was reading where somebody suggested something to a manufacturer
and the idea was not readily accepted and I likewise have made what I
thought were excellent suggestions and was met with similar responses
- this styrofoam thing was just one of them.
