Halocarbon 27 oil is a popular Drosophila breeding medium. It is a high molecular weight polymer of chlorotrifluoroethylene (PCTFE). This inert oil is manufactured by a controlled polymerization process and then is stabilized to give it some very unique properties. This oil is safe, chemically inert and nonflammable and is oxygen compatible and chlorine compatible. It has good lubricity, high thermal stability and low compressibility.
