200–400 Mesh Square-Hole Copper TEM Grids with Carbon Support Film

Product Description
Square-hole TEM grids provide a wide viewing area and are commonly
used for biological specimen preparation.
They are often used to pick up ultrathin sections from a water bath.
The high open-area ratio allows more specimen areas to be characterized.

Grid Material Comparison
| Grid Material | Characteristics |
|---|---|
| Copper Grids | Widely used and relatively inexpensive. Non-magnetic. Copper is reactive at low pH values. |
| Nickel Grids | Stable performance and high strength. Magnetic and may adhere during handling. Non-magnetic tweezers are recommended. |
| Gold Grids | Less likely to react with other substances. Gold is soft, easily deformed, less dimensionally precise and relatively expensive. |
| Molybdenum Grids | Low coefficient of contraction, high strength and high hardness. Suitable for research in high-temperature inert environments, where the supported specimen is less likely to deform. |
