16914-01, TYPE 37 IMMERSION OIL, 1 oz
37°C Immersion Oils
A number of research projects require microscopic studies at internal body temperature. Since the index/temperature relationship is inverse, increasing temperature significantly reduces the index of the immersion oil and consequently the imagery deteriorates. This problem has been resolved by the formation of Cargille 37°C Immersion Oils, which have an index of 1.515 at 37°C.
Consideration of these oils is also suggested where stage temperatures are elevated by sub-stage illuminators and high wattage projection equipment.
