SPI Supplies Brand Catalase TEM Test Specimen on 3.05 mm Copper Grid

This already prepared test sample consists of negatively stained catalase crystals on a Formvar/carbon film, revealing both 8.75nm and 6.85nm lattice spacings. These are well known natural materials constants and can be used for resolution, magnification and electron diffraction calibration procedures including image rotation. For those wanting the ultimate TEM calibration sample, consider the Mag*I*cal™ TEM Calibration Test Sample.

Packaging:
Gelatin capsule in a cushioned SPI hinged plastic box.
