Product Description

Formvar coated grids without a carbon layer are suitable for TEM applications up to 100kV. The films are available on grids made of copper, nickel or gold.

Supplied as 25 grids in a grid box.

Gold

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

Optimized Support for TEM Specimens

Designed for electron microscopy, these Formvar-coated gold slot grids provide exceptional support for fragile samples. Their rectangular slot shape and ultra-thin Formvar film ensure high transparency and minimal interference with specimen imaging, enabling clearer visualization and analysis at microscopic levels.

Premium Materials for Consistent Performance

Manufactured from pure gold and high-purity Formvar, these grids offer superior chemical stability and physical robustness. The precision coating method produces a continuous, smooth film, guaranteeing uniform surface quality and consistent results across every grid in the pack.

Safe Handling and Reliable Storage

To maintain film integrity, grids should be handled with antistatic tweezers and stored in a dry, room-temperature environment away from direct sunlight. Following these guidelines ensures the longevity and performance required for demanding laboratory and microscopy experiments.

FAQs of Formvar on 2mm x 1mm Au Slot Grids (Pack of 25):

Q: How should Formvar on Au slot grids be handled to prevent film breakage?

A: Use antistatic tweezers when handling the grids to avoid damaging the delicate Formvar film. This reduces static discharge and ensures the film remains intact for specimen mounting.

Q: What is the typical usage of these Formvar-coated gold slot grids?

A: They are primarily used for mounting biological or particulate samples for transmission electron microscopy (TEM), supporting precise imaging and specimen analysis.

Q: When is it necessary to use Formvar on gold slot grids instead of standard mesh grids?

A: Formvar on gold slot grids is preferred when specimens require a smooth, continuous film and an inert metallic substrate for enhanced sample stability and imaging clarity, which may not be achievable with standard mesh grids.

Q: Where should these grids be stored to maintain their quality?

A: Store the grids in a dry container at room temperature and keep them away from direct sunlight to preserve the smoothness and uniformity of the Formvar film.

Q: What benefit does the pure gold construction provide for TEM applications?

A: Pure gold offers chemical inertness, physical stability, and excellent conductivity, preventing sample contamination and delivering high-quality results during electron microscopy.

Q: How does the coating process affect grid uniformity?

A: The continuous Formvar film coating method creates a smooth, uniform surface over the slot, ensuring consistent transparency and specimen support for each grid in the pack.

Q: What solvents can dissolve the Formvar film on these grids?

A: Formvar is insoluble in water but can be dissolved in aromatic hydrocarbons and chlorinated solvents, useful for removal or chemical studies.
