The bottom line: this 1 Oz (30mL) bottle is for users who need a high-viscosity, reusable immersion oil with a stable refractive index of ND 1.515 standardized at 23 C. It is best suited to frequent users who require consistent optical performance at high magnifications and for oil-immersion objectives; beginners may prefer a lower-viscosity Type A oil for easier cleanup.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType B high viscosity:\u003c\/strong\u003e Higher viscosity increases longevity on the lens so the oil remains effective across multiple uses before needing reapplication.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefractive index ND 1.515:\u003c\/strong\u003e Matches the optical path at high magnification to provide improved resolution and image contrast when used with oil-immersion objectives.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVolume 1 Oz (30mL):\u003c\/strong\u003e A small, serviceable bottle size that is convenient for bench use without excessive waste for individual labs or classrooms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeets ISO-8036\/1:\u003c\/strong\u003e Standardized manufacturing ensures consistent performance and compatibility with oil-immersion optics and condensers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe for lenses:\u003c\/strong\u003e Formulated to be safe on optical lens surfaces when used as directed and not intended for dry or water-immersion objectives.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Type B immersion oil is designed for professional microscopists, clinical labs, and advanced hobbyists who work frequently at high magnifications and need a stable, reusable oil.
