Hi Folks,
        We have a Nikon Diaphot connected to our Bio-Rad Confocal.  The
slider on the prism that shunts the laser up or the transmitted light to
the oculars is getting very hard to pull.  Nikon originally said this is
natural and to replace the silicon gel on the prism glides inside the
housing, preferably by their own gel.  They now say that we should use a
high quality oil instead of the gel.
        Since this is a big deal, hard to do thanks to the confocal
assembly, I thought I would ask if anyone else out there has run into this
problem.
        TIA
