Product Description

Ultra-thin support films are carbon films with a removable Formvar backing on the opposite side of the grid. The Formvar is then removed by dipping in solvent and the pure carbon film remains. These films are stable under all EM operating conditions and can be used where the presence of a Formvar layer is not acceptable. As thin pure carbon films alone have the tendency to be more delicate than those with Formvar backing support they require more delicate handling during specimen preparation. Leaving the Formvar in place until sample preparation is complete ensures the carbon film remains intact.

These carbon films are available on 3.05mm dia copper grids.



Atomic-Scale Smoothness for Imaging Precision

The ultra-thin carbon support film features superior atomic-scale smoothness and uniformity, making it exceptionally well-suited for high-resolution transmission electron microscopy. This homogeneity ensures minimal background interference and optimal imaging clarity, especially critical in applications like structure determination or nanomaterial analysis.


Superior Electron Transparency for High-Resolution TEM

Designed for exceptional electron transparency, this 3nm support film allows clear visualization of fine sample structures. By providing a minimal and stable support background, the film enhances contrast and detail in biological and materials science TEM studies, supporting advances in research across multiple disciplines.


Precision Handling and Safe Storage

Due to its fragile nature, the film must be managed with fine, anti-static precision tools to prevent rupture or wrinkling. Each grid is delivered in a vacuum-sealed, dust-free container to maintain its cleanliness and quality. Proper storage in a dry, contaminant-free environment is crucial for long-lasting performance and reliability in laboratory settings.

FAQs of Ultra-thin carbon support film, 3nm:


Q: How should I handle the ultra-thin carbon support film to avoid damage?

A: Handle the support film using precision tools such as anti-static tweezers, and avoid touching the surface directly. The film is extremely fragile and can be easily ruptured or wrinkled by improper handling or physical force.

Q: What benefits does the 3nm film thickness provide for TEM applications?

A: Its ultra-thin, uniform structure offers high electron transparency, minimizing background signal and improving resolution for high-precision TEM imaging, including biological and material sample analyses.

Q: When is this carbon support film most effectively used?

A: The film is optimized for high-resolution transmission electron microscopy, cryo-EM sample preparation, and electron microscopy analysis, particularly when fine structural detail and high contrast are required.

Q: Where should I store the support grids to maintain maximum performance?

A: Store the grids in their original vacuum-sealed, dust-free storage box in a dry, clean, dust-free environment, away from static discharge and potential contaminants.

Q: What is the process for cleaning the carbon support film surface?

A: Each film is plasma cleaned during manufacturing, resulting in a hydrophilic and contaminant-free surface ready for immediate use in sample preparation and imaging.

Q: How does the carbon film adhere to different EM grids?

A: The carbon support film exhibits excellent adhesion to standard 3.05mm EM grids made of copper, nickel, or gold, ensuring reliable support and minimal detachment during sample handling.

Q: What are the key advantages of using this ultra-thin carbon support layer in research?

A: Researchers benefit from its high electron transparency, atomic-scale smoothness, consistent film uniformity, and robust purity, all contributing to clearer imaging, reproducible results, and versatility across various analytical scenarios.
