for transmission electron microscopy - packed in anti-static vials - useful for EDX analysis, high temperature and cryo applications
These grids are available in molybdenum, titanium, aluminum and stainless steel 316. The grids are made by a high precision etch-
ing process. The thickness is approximately 25µm for Mo and Al, 15µm for Ti and 12µm for stainless steel. The pattern with the 350-
400µm wide rim on the PELCO® grids provide greater stiffness and improves handling of the grids. All grids have a standard diameter of
3.0 to 3.05mm. Available styles are: square mesh, hexagonal mesh, double folding grids, tabbed grids, slotted and aperture grids. The
square mesh and double folding grids have a center mark. For standard grid materials such as Cu, Ni and Au, please go to the PELCO®
Grids page. Packaging: Mo, Ti, Al and Stainless Steel grids are packaged in 25grids/vial.

Gilder

The Gilder grids are available in 50 to an unrivalled 2000 mesh. The Gilder grids
feature well defined grid bars, shiny (smooth) and matt side difference and are
packaged in custom anti-static vials. They are made with precision electroplat-
ing technologies. An additional feature of the Gilder grids are the rim and centre
marks to aid in the orientation on the grid and identification of each side. Most
Gilder grids have a rim mark and many grids also have center marks. Wide selec-
tion of grid styles to support virtually every application with standard diameter of
3.05mm. Available materials are Cu, Ni, Au, Mo and Cu/Pd. Standard Mesh Grids with

Three .54mm x .95mm slots in a 3.05mm copper grid. Extra bars provide better support over a large
area. If a supporting film is ruptured in one area it may not effect the other 2 areas. This is an advantage
compared to one slot grids.

StrataTek™

StrataTek™ TEM Grids

The StrataTek™ TEM grids for Transmission Electron Microscopy have a thickness of 25um and are manufactured using a micron-preci-
sion etching process of thin foils. This method produces sturdy and rigid TEM grids. Both sides have the same surface characterization.
StrataTek™ grids have a slightly higher density than grids made by electroplating. Corners where bars meet tend to be rounded.
Available in coarser mesh sizes only, with configurations in square and hexagonal mesh, slot, hole and folding grids. Grids have stan-
dard diameter of 3.05mm.

Reference Finder Grids

Relocating a particular grid square or area by a logical alphabetical or numeric (or both) arrangement can reduce the time spent for
specimen analysis. Exact grid square definition may even be a requirement in forensic and asbestos analysis. Certainly there can be
greatly increased confidence by the electron microscopist that a precise grid square can be found where a feature is of interest while
moving about the other parts of the specimen on the grid.
Your need or wish can most likely be filled with one or more reference grid styles listed below.

number symbols appear on the bottom grid bars along the horizontal axis. Zero is represented by a
short pillar and one by a longer pillar. The enlarged section shown is of grid square no. 9 - a long pillar
at the extreme right represents decimal 1 and a long pillar fourth from the right represents decimal 8.

Athene grids production started 60 years ago, about 1948, and still retain the qualities which made the pioneer electron microscopists
appreciative: Sharp burr-free bars and corners, and close quality inspection. Different styles have been added over the years. Styles
available are square mesh, honeycomb and slots. Standard diameter is 3.05mm and materials are in Cu, Ni and Au.

The SynapTek™ grids are made of a special alloy (beryllium copper) which
makes these grids extremely sturdy and gives perfect stability for coat-
ing with a support film. These grids are easy to clean, contamination
free and reusable after cleaning. The thickness of the SynapTek™ grids
is 100µm (4 mil), diameter is 3.05mm. Standard oval slot size is 1x2mm. Notched SynapTek™ Grids permit easier grasping by tweezers.
The DOT type is also available with a slot size of 0.5x2mm. The gold
plated SynapTek™ grid (GILDED) has been developed for special applica-
tions such as immunology research. This innovative design may increase your confidence with grid handling.
DOT: One side of the grid is marked with 2 dots for clear identification, visible to the naked eye.
NUM: A number stamped on the grid for identification. Numbers are in random order and may be duplicated.
NOTCH: An indentation is stamped on one side of the grid to enable easy grasping by tweezers.

Formvar Ni, 200 mesh Hex Mo, 300 mesh Cu or Au, 300 mesh Hex Mo, and 400 mesh Cu.
Grid Support films on the finer mesh grids can withstand considerable handling during specimen
preparation. Those on slot and 75 mesh grids require more gentle handling and are ideal for
those applications requiring large viewing areas without grid bar interference.
Our popular line of NetMesh™ Grids (our trademarked lacey films) are available on 200 and 300
mesh grids. These robust films allow for viewing of specimens without interference from under-
lying support film material.
The complete PELCO® line of support films meets the requirements of most applications in all
fields of electron microscopy.
We Offer Seven Types of Support Films
1. Formvar
2. Formvar, Stabilized with Carbon
3. Carbon Type-B
4. Carbon Type-A
5. Pure Carbon Film
6. Silicon Monoxide
7. Lacey Support Films - NetMesh™ Grids

n 2. Formvar, Stabilized with Carbon: A Formvar film covered with a “light” layer of carbon. The heat and
electrical conducting properties of carbon help to stabilize the Formvar films when exposed to the electron beam. This is a resilient, all-
purpose specimen support film, ideal for mounting thin sections and for applications using lower ranges of magnification. The 200M-
TH grids (Prod. No. 01803 and 01803-F) are thicker and more rigid than normal and useful for many applications - particularly where

of the grid. When the Formvar is removed, by dipping in solvent, a pure carbon film remains. (Note: The
Ultrathin Carbon Film on a Holey Carbon Support Film, Prod. No. 01824, has no Formvar backing.) These

n 6. Silicon Monoxide: Silicon monoxide produces a highly resilient support film which can withstand vigorous specimen
preparation techniques. It has low background contrast, is stable under the electron beam and is less hydrophobic than carbon. We
offer two types of silicon monoxide support films:
(a) Formvar Stabilized with Silicon Monoxide: A Formvar film coated with a “light” layer of silicon monoxide.

n 7. Lacey Support Films - NetMesh™ Grids: Lacey Support Film

A lacey network support film. The holes in the lacey support film vary in size from less than a
quarter micron to more than 10 microns making them ideal for any type of specimen. Lacey
support films are strong and withstand vigorous specimen preparation treatment. The speci-
men material is supported by the film network but lies across or protrudes into the holes of
the mesh. This allows high definition imaging without the effects of underlying support ma-
terial. Lacey films can be used for specimens ranging from large crystals and other particu-
Lacey Support Film 0.26µm dia. Latex on a
late material to virus particles. Smaller particles, such as viruses or bacteria, tend to adhere Lacey Support Film, ex-
around the inner edges of the holes, an ideal situation for high resolution microscopy. Lacey ample of application
films are also ideal for selected area electron diffraction imaging. We offer three types of Molybdenum Trioxide

(b) Lacey Carbon Type-A: A Lacey carbon film with a removable Formvar backing on the opposite side of the grid. When the For-
mvar is removed, by dipping in solvent, the Lacey carbon film remains. These films are stable under all EM operating conditions and for
use where the presence of Formvar can not be tolerated. Pure Lacey Carbon is more delicate than those with Formvar backing and re-
quire more careful handling during specimen preparation.
