Coors Porous Bottom c r u c i b l e s give t h e chemist sturdy, dependable filtering cruci bles for unlimited service under the most exacting conditions. An exclusive process developed by Coors provides a porous disc, formed into the crucible wall, that will not crack or drop out during use at room or elevated temperatures. The disc will not dis integrate when subjected to acids (except HF) or moderate alkali solutions. When these Coors crucibles ate ignited even to extreme ly high temperatures, the porous disc will not crack, nor will the pore size be altered. Carefully controlled pore sizes are available in three ranges: (1) for bacterial separation and (2) fine filtering and (3) coarse pre cipitates. The crucibles are easily cleaned and readied for re-use. The same filtering disc may be ordered in the Coors Emich micro-filter stick for immersion filtration. Write for Bulletin No. 548. Coors Porous Bottom crucibles are immediately available through your nearest laboratory supply dealer. INSIST THAT YOUR LABORATORY PORCELAIN WARE CARRY T H I S MARK OF DEPENDABILITY
