2465a CRUCIBLE HOLDER, Sargent's, for filtering crucibles. The 

 simplest apparatus for the purpose on the mar- 

 ket. It is of special value where the unob- 

 structed use of the entire sides and bottoms of 

 porous filters is desired, as it grasps only about 

 one-eighth of an inch of the upper rim of the 

 crucible. Can be instantly installed or removed 

 for cleaning. Will fit any ordinary sixty degree 

 funnel. Can be used with any crucible on the 2465c 



market, such as Gooch, Caldwell or porous 

 Alundum styles. Made of one piece of soft rub- 

 ber in three sizes only.

 Gooch Crucible Holder cannot be equalled. Hot acid solu- 

 tions can be filtered without danger of contamination, as the 

 rubber plug is completely lined inside with a bell-shaped 

 g-lass covering. The taper of the plug is so designed as to 

 fit flasks of various sized necks. One complete holder will 

 take the place of the usual carbon tube, rubber stopper and 

 tubing. Each, complete, but without crucible $0.50
