Specifications Formulated for specific applicationsMeets DIN 58 844 requirementsPCB freeNon-dryingRefractive index and temperature standardizations are key specifications for optical clarity and high resolution. Viscosity and other physical properties are directed toward specific applications and user convenience. For most applications, optimal refractive index (D Line- 5893 A) is 1.5150 at 23°C.Type A (low viscosity) or Type B (high viscosity) oils are recommended for routine applications.Extra High Viscosity oils such as Cargille Type NVH and Type OVH are used with inverted or inclined microscopes when lower viscosity oils may run out of place or on to surfaces where they are not wanted. These oils are capapble of bridging a wide condenser gap or the wide gap between objective and slide when using long working distance oil immersion objectives. Type A and Type B oils bridge a gap of 2.8 mm while Type NVH bridged a gap of 3.5 mm and Type OVH bridged a 4.4 mm gap. All Cargille oils may be blended for intermediate viscosity.For fluorescence work, Cargille offers Type DF Very, Very Low Fluorescence and Type FF Fluorescence-free oils. Type DF meets requirements specified by DIN for refractive index and dispersion and has a slight green background fluorescence, making it ideal for observing low levels of fluorescence. It is highly stable, water white and non-hygroscopic and can be used in nearly all fluorescence applications. nD at 23C is 1.4790Refractive index, color absorption properties and viscosity of Type 300 oil are adjusted to meet the exacting requirements for proper operation of automated hematology systems.Type 37 has a refractive index of 1.5150 at 37°C for use in studies conducted at body temperature or where stage temperatures are elevated by substage illuminators and high wattage projection equipment.Thomas No.TypeViscosity (cSt) @ 23°CPKG.6705C25A1500.25 oz.6705C27A1501 oz.6705C29A1504 oz.6705C31A15016 oz.6705C33B12500.25 oz.6705C35B12501 oz.6705C37B12504 oz.6705C39B125016 oz.6705C41NVH21,0000.25 oz.6705C43NVH21,0001 oz.6705C45NVH21,0004 oz.6705C47OVH46,0001 oz.6705C49OVH46,0004 oz.6705C51DF3300.25 oz.6705C53DF3301 oz.6705C55DF3304 oz.6705C57DF33016 oz.6705C59FF1700.25 oz.6705C61FF1701 oz.6705C63FF1704 oz.6705C65FF17016 oz.6705C673003001 oz.6705C693003004 oz.6705C7130030016 oz.Thomas No.TypenD @ 37°CPKG.6705C733712501 oz.6705C753712504 oz.Thomas No.TypeViscosity: 700 cSt ± 10% @ 23°C (Medium)PKG.1144C16HF7001 oz.1144C17HF70016 oz.
