  • Patent number: 4565721
    Abstract: Carbowax PEG 1450 is the essential ingredient needed in preparing the alcoholic fixative now commonly used in cancer cytology. A new method is described showing how carbowax PEG 1450 sticks of uniform weight and length can be manufactured in thin polyethylene molds. The mold which is easily cut thru with a razor blade is left on to protect the wax stick until it is used. From these sticks any desired smaller weight of carbowax PEG 1450 can be calculated from markings stamped on the mold surface, from measurements on an English or metric straight ruler, or from an algebraic line graph or conversion table supplied with the molded stick. The vertical axis of the graph can be used for making measurements in either centimeters or inches. Thus it is no longer necessary to weigh out the small quantity of carbowax PEG 1450 needed to prepare the usual small volume of fixative needed for every day office or clinic use. Suggestions are given showing how the carbowax PEG 1450 fixative can be used.
