De Khotinsky Electrically Heated 



CREMATOR 



No. K1750. 



In inoculating culture tubes or making sputum smears the spattering occasioned by 

 flaming the platinum loop in the Bunsen burner flame has long been recognized as undesir- 

 able, especially as it is a source of great danger to the health of the operator. This trouble 

 is entirely done away with in the de Khotinsky Cremator, in which the flaming of the loops 

 may be performed with perfect safety. The rapid flaming requires only a few moments and 

 is complete, since the bright red heat to which the loop is subjected removes all carbonized 

 material. The apparatus consists of a tube of heat resisting material 4 inches long by | inch 

 inside diameter, closed at one end and wound with nichrome wire. This tube is mounted in 

 a neatly finished brass tube of If inches outside diameter, and the space between the two 

 tubes is filled with magnesia-asbestos mixture C85 per cent magnesia and 15 per cent asbestos^ . 

 This tube is mounted on a base of asbestos board, which is fitted with binding posts for 

 electrical connection and with a suitable support for the handle of the platinum loop. The 

 Cremator is furnished for both 110 or 220 volt current. In ordering, state voltage.
