The use of immersion oils in light microscopy increases the resolving power of the microscope by replacing the air gap between the immersion objective lens and cover glass with a high refractive index medium and reducing light refraction.

Cargille Immersion Oils: 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.

Type A and B: Normal light microscopy 
Type 37: Elevated temperatures (>23°C to 37°C) 
Type 300: Automated haematology systems
Type NVH or OVH: Inverted, inclined, projection, and long focus instruments
Type LDF and HF: Fluorescence microscopy, extremely low fluorescence
Type FF: Nearly fluorescence-free Immersion oil (not ISO compliant)

EMS Immersion Oils: EMS have introduced a complete new line of immersion oils. This new family includes 5 unique types.

  • Critical use
  • Synthetic
  • High viscosity
  • Low viscosity with R.I 1.480 (Synthetic)
  • Low refractive index (1.455) – suitable with aqueous media


LM Immersion Oils

ProSciTech supplies immersion oils for light microscopy, including trusted formulations from Cargille, designed to match refractive index requirements for oil immersion objectives and improve image resolution, contrast, and optical clarity. Suitable for brightfield, phase contrast, and fluorescence microscopy, these oils support biological, histological, and research applications requiring high magnification imaging. Options include standard and low autofluorescence immersion oils for consistent and reliable performance across routine and advanced microscopy workflows.
