There is nothing in the chemical line which we cannot furnish. You will find us prompt, courteous and reliable In our Glassblowing Establishment we can produce any apparatus, no matter how complicated De Khotinsky Electrically Heated CREMATOR. No. K1750. In inoculating culture tubes or making sputum smears the spattering occasioned byflaming 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 troubleis entirely done away with in the de Khotinsky Cremator, in which the flaming of the loopsmay be performed with perfect safety. The rapid flaming requires only a few moments andis complete, since the bright red heat to which the loop is subjected removes all carbonizedmaterial. The apparatus consists of a tube of heat resisting material 4 inches long by | inchinside diameter, closed at one end and wound with nichrome wire. This tube is mounted ina neatly finished brass tube of If inches outside diameter, and the space between the twotubes 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 wi
