De Khotinsky 

 Fixing and Hot Staining Apparatus 



No. 8049A 



Electrically Heated 



This apparatus meets the need for a clean and neat apparatus for hot staining. By 

 its use it is possible to fix the smears of sputum, etc., without danger of burning, to stain 

 them without danger of boiling the carbolfuchsin solution and also to avoid dropping carbol- 

 fuchsin over the laboratory tables and floors. It consists of an asbestos wood frame with 

 base which will stand red heat without destruction. In the bottom is a sliding metal shelf, 

 to be filled with sand for catching any drippings and to aid in reflecting all the heat upward 

 from the heating units, of which there is one for every two slides. These units, which are 

 easily replaceable, are made of lavite, bound with nichrome wire, which is insoluble in boil- 

 ing carbolfuchsin. The slide carriers are nickel-plated brass frames made to fit in the as- 

 bestos frame at a suitable height above the electrical units. The base is provided with 

 leveling screws. A set of fuses is placed on the apparatus, so that there is no danger from 

 accidental short circuit. The apparatus is made in two sizes, as listed below, and is in- 

 tended for standard 3 x 1 in. slides. It consists of heating box, slide carrier, tray, cross test 

 level and five feet of cord with two plugs. For 110 volts A. C. or D. C. and furnished with 

 a rheostat for close regulation of heat.
