Product Description

These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on copper grids. The composite films have extra resilience and strength compared with carbon films. They are recommended for use where the grid has to undergo several processing steps during specimen preparation.

Supplied either in packs of 25 or 50 grids in a grid box depending on each particular product.

Formvar carbon support films can be applied to other grid sizes, material or type. Further details available on request.

High-Quality Construction for Reliable Results

Each grid is manufactured from high-purity copper with a Formvar and carbon support film, ensuring minimal background interference and optimal sample integrity. The grid structurea 2mm x 1mm rectangular slotfacilitates easy placement and analysis of TEM specimens. With EM grade quality, these grids support both biological and material sciences research with consistent results.

Convenient Packing and Storage

Grids come in packs of 50, securely protected within anti-static boxes to prevent contamination and preserve film quality. Their robust design maintains surface cleanliness and hydrophilicity, streamlining preparation and handling in demanding lab environments. Storage in dry, dust-free conditions ensures long-term usability.

FAQs of Formvar/Carbon on 2mmx1mm Slot Copper Grids (Pack of 50):

Q: How should Formvar/Carbon coated slot copper grids be handled during TEM specimen preparation?

A: Handle grids with clean, non-magnetic tweezers to avoid damaging the thin Formvar/Carbon film. Always hold the grid by its edge to maintain a clean, hydrophilic surface and reduce the risk of contaminating the film prior to sample application.

Q: What are the benefits of using Formvar/Carbon on 2mmx1mm slot copper grids in electron microscopy?

A: These grids provide a strong, conductive support surface, improving image clarity and sample stability during TEM analysis. Their clean, hydrophilic film ensures reliable sample adherence and compatibility with standard stains and reagents, supporting high-contrast and precise imaging.

Q: When is it appropriate to use slot grids rather than mesh grids?

A: Slot grids are ideal for supporting larger or elongated specimens that may be incompatible with finer mesh patterns. Their open rectangle slot enables optimal visualization of whole-mount samples, filaments, or elongated cell structures in both biological and materials research.

Q: Where is the best place to store these grids to maintain quality?

A: Store the grids in their anti-static box within a clean, dry, and dust-free environment. This prevents surface contamination and prolongs the integrity of the Formvar/Carbon film, ensuring consistent experimental performance.

Q: What process is used to create the Formvar/Carbon coating on the copper grids?

A: First, a thin layer of Formvar (polyvinyl formal) is deposited on the grid, followed by carbon evaporation to enhance stability, strength, and conductivity. This dual-layer approach ensures the film meets the demanding needs of TEM analyses.

Q: How compatible are these grids with common electron microscopy stains and reagents?

A: The hydrophilic Formvar/Carbon coating is engineered to resist standard electron microscopy stains and reagents. This compatibility allows for successful specimen contrasting and preparation without compromising film integrity.

Q: What are some typical applications of Formvar/Carbon slot copper grids?

A: These grids are used as specimen supports in TEM for both biological samplessuch as cells, viruses, and proteinsand material science applications, including nanomaterials and polymers. Their versatility makes them suitable for a wide range of academic and industrial studies.
