Immersion Oil
Immersion Oil is a high-purity, optically transparent oil used primarily in microscopy to enhance the resolution of high-power objectives. Applied between the microscope objective lens and the cover glass, immersion oil reduces light refraction and increases numerical aperture, allowing for clearer and more detailed imaging. It is colorless, non-drying, and has a refractive index closely matching that of glass (typically around 1.515).
This 50ml volume is ideal for laboratory, clinical, and educational settings where precision microscopy work is performed. Immersion oil is formulated to be chemically stable, non-drying, and safe for delicate optics when used correctly.

Sassafras Oil
Sassafras Oil is a potent essential oil distilled primarily from the bark of the Sassafras albidum tree, native to North America. Steam distillation yields a yellow to reddish-brown oil with a strong, sweet, root beer–like aroma due to its primary constituent, safrole. Historically used in perfumery, flavoring, and herbal medicine, Sassafras Oil possesses aromatic, antiseptic, and stimulant properties.
Despite its traditional applications, safrole-containing Sassafras Oil is strictly regulated in many countries due to potential hepatotoxicity and carcinogenicity associated with safrole. As such, modern uses are limited, and safrole-free versions are required for legal use in personal care or flavoring. In compliant forms, it finds niche use in natural fragrances, industrial solvents, and botanical extracts.
