Hi All,


I have been using Euparal for some time now as the mounting medium for cuke ossicles.  It does not have the crystallization – age problem of Permount.  However it has the wrong refraction index, so that some of the ossicles that have their optical axes in the “wrong” direction appear much fainter than others in these preps.  In contrast the same ossicles look terrific when viewed in just water.  Does anyone know of a better alternative – i.e. a permanent mounting medium without these optical issues that also does not crystallize?


Thanks – Gustav
