Cargille immersion oil, type LDF (EMS)
Cargille was first to introduce PCB-Free immersion oils in 1972. Though all immersion oils are now PCB free, no other immersion oil meets FDA criteria; and Cargille's exceeds ISO, DIN and all instrument manufacturer's standards.
Minimum shelf life of these immersion oils is 5 years and can be twice that.
The best immersion oil for fluorescence microscopy, LDF has extremely low background fluorescence (Cargille # 1-2). It has excellent optical values of refractive index (1.515 at sodium yellow 5893 angstroms and 1.518 at mercury green 5461 angstroms) and dispersion (41.3 for Abbe υD) for a sharp image. It has a medium viscosity of 500 cSt. It has an odour, (1-bromonaphthalene), that some people dislike.
Refractive Index @ 23°C:
F Line (486.1nm) - 1.5239
e Line (546.1nm) - 1.5181
D Line (589.3nm) - 1.5150
C Line (656.3nm) - 1.5115
Viscosity: 500cSt ± 10% @ 23°C (Medium)
