SYNTHOL 



(ABSOLUTE) 



A chemically pure synthetic sub- 

 stitute for absolute ALCOHOL. 



PURER, STRONGER, MORE STABLE, CHEAPER. 



YNTHOL may be used for every purpose for which 

 alcohol is used, except for internal consumption. 

 Being chemically pure it does not have as much odor 

 as absolute alcohol from grain or wood. It is perfectly free from 

 color, is non-irritant to eyes or skin and has from ten to fifteen 

 per cent, more solvent power than ordinary alcohol.

As a killing, fixing, or hardening agent it is in every respect equal 

 to the best absolute alcohol and can be used as a substitute for it in the 

 preparation of stains, reagents, etc. We offer a special low price on Synthol 

 in barrel lots FOR MUSEUM PURPOSES. As a preservative it is 

 superior to any alcohol. Alcohol becomes tinged with color on expos- 

 ure to light. Synthol retains its absolute colorlessness under all condi- 

 tions. Sample supplied free to laboratories.
