Holey Carbon Film TEM Grids with Continuous Carbon Coating

Introduction

Holey Carbon Film TEM Grids with Continuous Carbon Coating combine the advantages of perforated carbon support with an additional continuous carbon reinforcement layer. This dual-structure configuration enhances mechanical stability, improves conductivity, and reduces charging effects while preserving the benefits of open imaging regions.

These grids are widely used in cryo-electron microscopy (cryo-EM), nanoparticle analysis, and advanced materials characterization.

Film Structure and Design

This configuration consists of:

• A holey (perforated) carbon support film
• An additional thin continuous carbon coating

The perforated base film provides random open areas for suspended specimen imaging, while the continuous carbon layer increases structural integrity and beam resistance.

This design improves overall durability compared to standard holey carbon films.

Key Advantages

Holey Carbon Film TEM Grids with Continuous Carbon Coating offer:

• Enhanced mechanical stability
• Reduced charging during imaging
• Improved beam resistance
• Reinforced hole edges
• Greater handling durability
• Maintained open imaging areas

Applications

These grids are particularly suitable for:

• Cryo-EM sample preparation
• Single-particle analysis
• Nanoparticle suspension imaging
• Structural biology
• High-resolution TEM
• Materials science investigations

Available Base Grid Materials

• Copper TEM grids
• Molybdenum TEM grids

Multiple mesh sizes (e.g., 200, 300, 400 mesh) are available to match your imaging requirements. Copper and molybdenum substrates are available as standard. Additional base materials - including tungsten, nickel, titanium, and nylon - are available upon request. Please contact us to discuss custom grid configurations.
