Catalase Crystals
Catalase crystals, negatively stained, are mounted on a grid.
They display very clear lattice plane spacings in the TEM and STEM of 8.75nm and 6.85nm.
Wrigley, J, (1968). Ultrastructure Res, 24, 454.
Valuable for high magnification calibration.

Ferritin
Resolution of the tetrad of this molecule indicates an instrument resolution better than 1.25nm.
The ferritin is dispersed on a formvar/carbon substrate supported by a G400, 400 square mesh copper Gilder grid.

Gold on "Holey" Carbon Film
The spaces formed between "islands" of evaporated gold are ideal for checking
TEM/STEM (3mm grid) resolution. The holes allow for simultaneous astigmatism correction.
Made on a G400, 400 square mesh copper Gilder grid. |

Evaporated Platinum / Iridium
Evaporated Pt/Ir on perforated holey carbon film. Support film provides holes for ease of focus and astigmatism correction.
The grains of evaporated metal provide dense particles for TEM resolution checks by the particle separation test.
