[Histonet] Leica CM1850uv

[King, Laurie]

I've worked with 4 of these units, two had the problem, two didn't. Long story short, the problem won't go away until you have the Peltier unit replaced. That is not normal ice buildup.

We purchased a Leica CM1850uv cryostat in 2007 and we constantly have
problems with buildup of ice

on the specimen metal bar.   This causes the tissue to stick to the
stationary heat extractor which causes

significant problems cutting frozen sections.  The engineer has serviced
the machine several times, but

recognizes this as "normal ice buildup".

We manually defrost the unit 2-3 times a day, but it does not seem to
help.

Is anyone else experiencing the same problem, and if so, what are they
doing about it?  Thank you.
