The Avantor® ACE® C18-AR phase utilises a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for ‘standard’ C18 column separations, but is additionally recommended for separations that involve compounds containing aromatic functionality.

Standard agarose is a purified linear galactan hydrocolloid isolated from agar or agar-bearing marine algae with an Electroendoosmosis (EEO) value of 0.12 making it an essential component in chemical separation techniques.
Standard agarose is a very low electroendosmosis agarose (EEO) which is recommended for sharp resolution of nucleic acid fragments greater than 400 bp and up to 8000 bp. This Standard Agarose may be used at concentrations between 0.8 % and 2 %. Southern and Northern transfers can be performed efficiently from them.
