Graham-Field Grafco Micro Cover Glasses

Yes, a primary and crucial function of the Graham-Field Grafco Micro Cover Glasses is to provide essential protection for your microscope’s objective lens.

They act as a physical barrier designed to ensure the integrity and longevity of your equipment by:

• Preventing Direct Contact: They stop the objective lens (especially immersion objectives) from touching the liquid specimen or immersion oil on the slide.
• Minimizing Contamination: By preventing contact, they help reduce the risk of cross-contamination and maintain the cleanliness of the lens optics.

Additionally, the use of a cover glass is vital for optimized specimen viewing. It uses surface tension to flatten the liquid sample, confining the specimen to a single plane and allowing for effective, high-power focusing.

Yes, Graham-Field Grafco Micro Cover Glasses are specifically engineered to significantly enhance focus and protect your equipment during high-power microscopic examination.

Key benefits include:

• Precision Flattening: They utilize surface tension to flatten liquid drops, confining the specimen to a single optical plane. This minimizes the need for constant refocusing and allows for high-power focus close to the specimen.
• Objective Lens Protection: They act as a crucial barrier, preventing immersion objective lenses from directly contacting liquid samples, ensuring the lens remains clean and unobstructed.

These cover glasses are available in two standardized grades (both 22 x 22 mm) to meet specific resolution requirements:

• Grade #1 (0.13 - 0.18 mm thickness): Ideal for demanding applications, such as oil immersion or high-resolution work.
• Grade #2 (0.17 - 0.25 mm thickness): Suitable for general laboratory applications.

Yes, these Grafco Micro Cover Glasses are specifically designed to optimize specimen viewing, especially for high magnification and high-resolution microscopy. They are essential accessories for effective observation.

Key benefits include:

• Precision Focusing: They utilize surface tension to flatten the liquid sample, confining the specimen to a single optical plane. This stability minimizes the need for constant refocusing, allowing for sharp, reliable observation.
• Lens Protection: They act as a critical barrier, preventing the objective lens (especially immersion lenses) from making direct contact with the liquid sample, thereby protecting the lens from contamination and damage.

They are available in two grades based on thickness, catering to different applications:

• Grade #1 (0.13 - 0.18 mm): Recommended for critical applications such as oil immersion and high-resolution work.
• Grade #2 (0.17 - 0.25 mm): Suitable for general laboratory applications.

The Graham-Field Grafco Micro Cover Glasses are essential for optimizing specimen viewing and protecting your microscope equipment through two primary functions:

• Specimen Confinement and Flattening: The cover glass uses surface tension to flatten the liquid specimen, confining the sample to a single, consistent focal plane. This crucial action minimizes the focusing adjustments required, which is vital for achieving high-power objective resolution.
• Objective Lens Protection: They serve as a physical barrier, preventing direct contact between the sensitive objective lens and the liquid immersion medium or the specimen itself, protecting your valuable equipment.

These 22 x 22 mm cover glasses are available in two specific grades based on thickness, ensuring the right quality for your application:

The Graham-Field Grafco Micro Cover Glasses are consistently sized at 22 x 22 mm but are offered in two different grades, each optimized for specific microscopy applications:

• Grade #2 (0.17 - 0.25 mm Thickness): This standard grade is suitable for general laboratory applications and routine observation.

Yes, the Type #1 cover glass is specifically designed and recommended for demanding applications, such as high-resolution work and oil immersion microscopy.

This type features a precise thickness range that optimizes clarity when using high-power objectives.

• Recommended Use: Oil immersion or high-resolution work
• Thickness Range: 0.13 - 0.18 mm
• Standard Dimensions: 22 x 22 mm

Yes, Grafco Micro Cover Glasses are made of glass.

The Grafco Micro Cover Glasses are designed to confine the specimen to a single plane, which significantly reduces the need for constant refocusing during observation.

Yes, the Graham-Field Grafco Micro Cover Glasses come in the standard 22 x 22 mm square size, making them compatible with common microscope slides. These cover glasses are essential for microscopy, as they flatten liquid specimens using surface tension and protect the objective lens from contact with the sample. They are available in two specific grades, differentiated by thickness, to suit various applications: * Grade #1 (0.13 – 0.18 mm Thickness): Recommended for oil immersion or high-resolution work where precise optical thickness is crucial.* Grade #2 (0.17 – 0.25 mm Thickness): Ideal for general laboratory applications and standard observation.

Yes, these Grafco Micro Cover Glasses are highly suitable for various laboratory uses. Specifically, the #2 cover glass (0.17 - 0.25 mm thickness) is designed for general applications, while the #1 cover glass (0.13 - 0.18 mm thickness) is recommended for oil immersion or high-resolution work. They are ideal for clinical laboratories, research facilities, and educational settings.
