Bare TEM Grids – Double Folding (Oyster Type)
Double folding TEM grids designed to securely hold samples by sandwiching them between two grid layers.
Description
🔹 Description
Double folding TEM grids consist of two grid layers connected by a hinge, allowing the grid to be folded and closed to trap the specimen securely between them.
This design is particularly useful for samples that cannot adhere to standard TEM grids, such as metal foils or larger particles.
🔹 Specifications
| Product: | Transmission electron microscopy (TEM) grids / copper (Cu) grids |
