High Viscosity Immersion Oil is a premium optical medium designed for microscopy applications requiring stable, high-resolution imaging. Formulated to match the refractive index of glass, it enhances light transmission and image clarity when used with oil immersion objectives. The high-viscosity formulation resists spreading and evaporation, providing a stable oil film that is ideal for prolonged observation, photomicrography, and detailed analytical work. Suitable for clinical, research, educational, and industrial laboratories, it delivers consistent optical performance and reliable results. Supplied in convenient, chemically compatible containers for precise dispensing and storage.
