Product Description

Holey carbon films have many uses in microscopy but for certain applications the mesh sizes of standard TEM grids are too large to support the sample. Continuous carbon films can also be a problem due to the fact that the thin film can inelastically scatter electrons and contribute to background noise. Holey carbon films therefore are a suitable alternative.
Holey carbon films have holes of various sizes up to 100m. In addition to providing support, the increased image contrast in the regions of the holes compared to regions of film is also of benefit. Typical applications include biological and materials science and cryo-TEM.

Supplied as 25 or 50 grids in a grid box.
Holey carbon support films can be applied to other grid sizes, material or type. Further details available on request.

Precision-Engineered for TEM Applications

Our holey carbon film grids are tailored for researchers needing enhanced sample support during transmission electron microscopy. With high purity carbon films and consistent grid geometry, these grids facilitate efficient imaging across a broad assortment of TEM samples.


Adaptable and Easy to Use

The grids come with an untreated carbon surface, enabling users to glow discharge them according to application requirements. Their robust copper support ensures easy handling when using TEM tweezers, minimizing the risk of film damage during sample preparation.


Superior Stability and Longevity

Designed for high vacuum compatibility, these grids are stable at elevated temperatures and chemically inert, ensuring reliable performance during demanding TEM analysis. With an indefinite shelf life when stored in a clean, dry environment, they are a dependable laboratory consumable.

FAQs of Holey Carbon Films on 200 Mesh Copper Grids (Pack of 50):


Q: How should holey carbon films on copper grids be handled to prevent damage?

A: Handle the grids only with fine-tipped tweezers and avoid touching the grid center where the carbon film is present, as the thin film is delicate and can rupture easily. Hold the grid at the edges or on the copper bars for best results.

Q: What types of TEM samples are these holey carbon copper grids suitable for?

A: These grids are compatible with most biological and material science TEM samples, making them versatile for a wide range of sample preparation and imaging applications in research and industry.

Q: When is it necessary to treat the grid surface before using it for TEM?

A: The grids come with untreated plain carbon film. For applications requiring enhanced hydrophilicity or to remove surface contaminants, glow discharging the surface before sample application is recommended.

Q: Where should I store unused holey carbon copper grids for optimal shelf life?

A: Store the grids in a clean, dry environment at room temperature, ideally inside grid storage boxes. Protect them from dust, moisture, and direct contact to maintain their integrity and performance indefinitely.

Q: What are the benefits of using perforated (holey) carbon films for TEM imaging?

A: The holey carbon films minimize background scattering and provide support while allowing direct visualization of suspended particles. This structure is especially advantageous for imaging nano and biological specimens with high contrast and detail.

Q: How do I prepare the holey carbon copper grids for sample loading?

A: If required, glow discharge the grids to render the surface more hydrophilic, then use fine tweezers to deposit your TEM sample only over the grid area supported by copper bars. Avoid touching or applying force to the center film to prevent rupture.
