Product Description

These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on gold 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 as 25 or 50 grids in a grid box.

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

Exceptional Sample Support for TEM

These grids are designed to meet rigorous TEM grid industry standards, offering ultrathin, stable films for high-resolution imaging. The combination of Formvar and carbon coating enhances sample adherence, minimizes background interference, and ensures electrical conductivity, all while maintaining structural integrity on the sturdy gold substrate.

User-Oriented Design and Reliable Handling

With a flat, slotted gold grid format, the support films are easy to handle using antistatic tools or tweezers. Each pack contains 25 grids, clearly labeled with a lot number for traceability. Their dust-free state and visual contrast between black support film and a bright gold grid aid in precise sample placement and inspection.

FAQs of Formvar/Carbon on 2mmx1mm Gold Slots (Pack of 25):

Q: How should I handle Formvar/Carbon on Gold Slot grids to avoid damage?

A: You should always handle these grids using antistatic measures and tweezers to prevent static adherence and physical damage. Touching the support film directly is discouraged as it can compromise film integrity.

Q: What is the main benefit of using Formvar/Carbon support films for TEM?

A: Formvar/Carbon support films provide an ultrathin, conductive, and dust-free surface ideal for TEM sample preparation. The carbon layer enhances electrical conductivity, reducing imaging artifacts, while the high-purity Formvar ensures stable specimen support.

Q: When should I replace TEM grids to maintain sample quality?

A: Replace your Formvar/Carbon on Gold Slot grids after 23 years, or sooner if signs of contamination or film deterioration appear, as shelf life depends on storage under dry, room-temperature conditions away from sunlight.

Q: Where are these grids commonly used in laboratory settings?

A: These grids are primarily used in transmission electron microscopy laboratories for sample preparation in research, quality control, and diagnostic facilities across academic and industrial environments.

Q: What process should I follow to store the grids for extended shelf life?

A: Store grids at room temperature in a sealed, moisture-free container, away from direct sunlight. Proper storage preserves their cleanliness and maintains the ultrathin support films integrity.

Q: Which TEM holders are compatible with Formvar/Carbon on Gold Slot grids?

A: These grids are designed to fit most standard TEM holders due to their industry-standard size and shape. Always verify holder specifications before use for optimal compatibility.

Q: What are the benefits of using ultrathin Formvar/Carbon films on gold slot grids?

A: Ultrathin films provide high transparency for electron beam passage, minimize scattering, and reduce background noise during imaging. The gold grid adds mechanical strength and chemical inertness, enhancing durability and sample reliability.
