SPI Slim-Bar® Grids
Designed for maximum open area for maximum sample information!
Introduction:
The SPI Slim-Bar® Grids were designed for those who want the very
maximum of open area when viewing their important samples. In addition to the bars
being thinner than conventional grids, in order to get them that thin, the grid
itself is overall thinner in the thickness direction. This is a real attraction
for anyone doing stereo electron microscopy.
Remember that with the thinner bars, the grid square size is larger for a given mesh
size. Hence, if you want to keep the hole size constant relative to conventional
grids, if you were using 200 mesh regular grids presently, then you might want to
use 300 mesh Slim-Bar.
Just how "slim" are the SPI Slim-Bar® Grids?
We are talking about 5µm instead of the typically 30 µm for "regular" grids.
Summary of advantages:
- Ultra-high transmission grids: offering the highest percent open area available. (Up to 88%!)
- Plenty of specimen support power with minimal edge effects.
- Ideally suited for working with small, delicate cryo-section fragments.
- All grids are 3.05 mm diameter, with a solid border for easy handling.
Order numbers include a code letter that indicates metal type:
- C=Copper
- N=Nickel
- G=Gold
- GC=Gold Plated Copper
- GN=Gold Plated Nickel
- Available in regular square, variable rectangular and hexagonal mesh.
- Try Slim Bar® grids from SPI: you'll see the difference!
- Gold plated copper and gold plated nickel grids inertness of gold, but
for a much lower price
- Thickness of all SPI Slim Bar® Grids: 0.008 mil (20.3 µm)
- Tab easily "snipped off" with the
SPI Tab Snip-It™
Be sure also to consider Coated Grids and the Custom Coating Service
from SPI Supplies. Remember we can coat virtually any grid you might
select, not just the "examples" that are shown in the coated grid section.
And upon special order (and a slightly higher premium in price) we can also
coat onto just about any grid you might select, the
Quantifoil® holey carbon support films.
