Comprising of 13
types with mesh repeat values ranging from 50 lines/inch to 600
lines/inch. The overall thickness of the grid depends on the mesh
repeat, and as a general guide the lower the mesh repeat, the
thicker the grid. The variation in thickness and bar/hole width in
a population of 100 grids (1 vial) again increases with a lower
mesh repeat.
Overall thickness variation :
• G50 : 25 microns, +/- 5 microns
• G600TT : 6 microns, +/- 2 microns
|
|

As an alternative to square mesh,
hexagonal mesh grids offer a higher support factor for a given
mesh repeat distance.
Overall thickness variation :
• G50HEX : 25 microns, +/- 5 microns
• G400HEX : 10 microns, +/- 2 microns |

14 types offer a
wide choice of specimen support. Parallel bar grids are
particularly useful for obtaining information from sequential
ribbons of sections.
Overall thickness variation :
• G50P/PB : 27 microns, +/- 5 microns
• G400P/PB : 12microns, +/- 2 microns
|

Comprising of 2
types, offering a different pattern of support.
|
|

Comprising of 6
different types, offering a wide choice of slot options for film
support. The larger the slot dimensions, the thicker the grids,
for maximum rigidity.
Overall thickness variation :
• G1X0.2 : 25 microns, +/- 3 microns
• G2X1.5 : 60 microns, +/- 6 microns
|

Comprising of 10
types, Aperture grids consist of one central circular hole. The
larger the aperture dimension, the thicker the grid, for maximum
rigidity.
Overall thickness variation :
• GA75 : 25 microns, +/- 3 microns
• GA2000 : 50 microns, +/- 5 microns

The 'HS' series are a development
from the earlier 'HH' ultra-high transmission grids. They offer an
alternative to the standard square mesh grid for use in
applications where it is important that the maximum area of
specimen is available for viewing in the microscope.
The open area of a G200HS is 40% greater than that of a standard
G200 |
The 'HH' series offers a very high
transmission value with the additional support of a hexagonal
pattern. They offer an alternative to the standard hexagonal mesh
grids for use in applications where it is important that the
maximum area of specimen is available for viewing in the
microscope. |
The Finder range of grids are
useful in applications where specific areas of mesh need to be
uniquely identified. These areas range from blocks of 1 to 9 grid
cells, and can typically be relocated using an alphabetical and/or
numerical code built into the mesh. |

Double grids, offering a
combination of mesh support values, are used primarily in
metallurgical applications for supporting thin metal foils. Two
grids are joined by a thin 'hinge', allowing one grid to be folded
on top of the other, trapping the specimen between them. The grids
have a curved securing tab which folds to the curvature of the
doubled grid. |
