Halocarbon 27 oil is popular drosophila breeding mediums. Halocarbon 27 oil is a high molecular weight polymer of chlorotrifluoroethylene (PCTFE). This inert oil is manufactured by a controlled polymerisation process and then is stabilised to give it some very unique properties. This oil is safe, chemically inert and non-flammable and is oxygen compatible and chlorine compatible. It has good lubricity, high thermal stability and low compressibility.
