Cargille Laboratories designed its immersion oil type 37DF to provide optical values at 37 °C for a sharp image. Immersion oil standardized for room temperature at 23 °C may cause a decrease in resolution when used at 37 °C because critical optical values of the oil change with temperature. The 37DF, as does the DF at 23 °C, offers very low background fluorescence, making it suitable for fluorescence microscopy applications. The oil is available in 1-, 4- and 16-oz bottles.
