MEDICAL AND BIOLOGICAL STAINING TECHNIQUES 



fading of even the most delicate stains, is miscible with xylol, 

 absolute alcohol, benzene, toluol, dioxane and many other solvents. 



CRISTALITE 



Refractive index 1-515 



This synthetic mountant has all the properties of Clearmount 

 except that it dries much more rapidly and is not miscible with 

 alcohol. 



D.P.X. 



Refractive index 1*515 



A synthetic mountant, devised by Lendrum and Kirkpatrick* 

 on which Cristalite and probably other proprietary synthetic 

 mountants are based. This excellent mountant, which is colour- 

 less and neutral and does not cause fading of stains has the added 

 advantage of being one of the least costly of all the synthetic 

 resinous mountants: however, there is a considerable degree of 

 shrinkage of the mountant on drying and it should therefore be 

 applied liberally to allow for this.

MEEDOL BALSAM 



Refractive index i'5i5 



A xylol miscible mountant, pale amber in colour and hardly 

 distinguishable in appearance from Canada balsam in xylol. This 

 is one of the least costly of all resinous synthetic mounting media. 

 Unlike Canada balsam, but like the other synthetic mountants 

 described in this paragraph, Meedol balsam has the advantage of 

 remaining neutral indefinitely under normal conditions of storage 

 and handling. 



FLUORMOUNT 



Refractive index 1*515 



A synthetic, colourless, neutral, xylol miscible, non-fluorescent 

 mountant for fluorescence microscopy.
