The Higher the Magnification - The More Detail You'll See

Magnification 40x
Magnification 1000x
Magnification 2500x

Magnification is the ability of your microscope to make small objects seem larger. As the magnification increases the area being viewed will be decrease is size but the detail of the area being viewed will improve.

Amscope microscopes come with multiple magnifications to aid you in finding the proper magnification for viewing each specimen.

Camera Connection Types

When comparing 2.0 and 3.0 there are few major differences. First the transfer rates. USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - that's 10 times faster.

Camera Resolution

The most important factor in ensuring successful microscopic imaging is choosing the appropriate optics and camera for your application that gives you more data and higher image quality. When selecting a microscope camera, it is best to base your decision on the most important requirements for your microscopic observation.

Key Features

  • High-viscosity immersion oil for prolonged use with high-magnification microscopes
  • Type B immersion oil can be used with multiple slides without the need to re-apply
  • Refractive index ND=1.515
  • Volume: 1 Oz (30ml)
  • Standardized at 23'C

Cargille Type B immersion oil is the ideal choice for high-volume, general-purpose microscopy. The high viscosity provides better longevity than Type A oil, making it suitable for multiple uses without the need to re-apply. Type B immersion oil is better suited for professional use.

Immersion oil is necessary for high magnification microscopy when using oil-immersion objective lenses. Do not use with dry or water-immersion lenses. Immersion oil should also be used on oil-compatible light-condensers when working at high magnifications, as the oil ensures a consistent refractive index throughout the optical path, providing the highest resolution possible. For beginners and occasional users, Type A low-viscosity immersion oil is recommended because of its ease of use. For advanced and frequent users, Type B high-viscosity immersion oil provides better longevity for use with multiple slides without the need to re-apply.

Immersion oil is not soluble in water. To thin or remove, use naptha, xylene, or turpentine, including Sparkle cleaner. Always follow standard safety protocols.
