LC Silica Columns

High purity, amphoteric alundum, specially treated with selenium for use in determination of amino and cyanide nitrogen. Four mesh granule size, iridescent bluish black color.

Application Useful as a support for immobilizing substrates on silica gel.

Bottoms are 60% thinner than conventional polystyrene plates, resulting in lower background fluorescence and enabling readings down to 340nm Opaque walls to prevent well-to-well crosstalk Optically clear flat well bottom permits direct microscopic vi
