The world's largest selection of TEM grids for transmission electron microscopy is found on the SPI Supplies website including copper, nickel, gold, and other materials of construction.
Nuclepore polycarbonate filters contain uniform, cylindrical pores, preferentially etched into the membrane, allowing for an even distribution of a collected sample in one plane across the entire exposed membrane surface. Contaminant-free, these microporous screens are biologically inert, and offer excellent chemical resistance and thermal stability.
Vacuum greases with outstanding performance under conditions of extreme temperatures and chemical environments. Perhaps best known for their high chemical inertness, the Braycote line of high vacuum greases has been developed to cover a wide range of temperature and chemical environments and are used in a very wide range of applications. Braycote greases are
