Cargille immersion oil, type 300 (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.Automated Haematology Systems: Use Type 300; Automated Haematology Systems depend on accurate, precisely controlled physical and optical properties of immersion oil for successful imaging and mechanical processing. Type 300 is designed and manufactured to meet the stringent requirements of this equipment, which include specialised viscosity and exacting controls for its consistency.Refractive Index @ 23°C:F Line (486.1nm) - 1.5238e Line (546.1nm) - 1.5180D Line (589.3nm) - 1.5150C Line (656.3nm) - 1.5115Viscosity: 300cSt ± 10% @ 23°C (Medium)

Technical Data

Blending Oils from the Miscible Group: The Miscible Group of immersion oils is A, B, NVH and OVH. Users can easily blend any two immersion oils from the Miscible Group to obtain an immersion oil with an intermediate viscosity while maintaining the optical properties common to both. Type 37 can be blended with type B.

All Cargille immersion oils are classed as low fluorescence, however, for work with weak fluorescence, types FF and LDF.

50ml is supplied in a high density polyethylene bottle with a pointed, twist closure suited to place single drops onto slides. For refills and large users these oils are available in larger glass bottles and in the original 3.785L steel cans with resealable pouring spout.

AVAILABILITY NOTE:  We will no longer be dispensing Cargille Immersion oil. Once our stock of dispensed oils are gone, these will be sold in the 29ml/1oz, 120ml/4oz and 473ml/8oz sizes only.
