InertSustain C18 Analytical Columns, Particle Size 3µm, I.D. 4.0mm, Length 30mm, GL Sciences Inc. (CAT#: STEM-C-1700-LC)

InertSustain C18 manufactured by GL Sciences Inc. uses a radically new type of silica whose surface is uniquely modified, enabling precise control of the silica properties.
InertSustain C18 features the advantages of all the current Inertsil HPLC columns, such as ultra low operating back pressure, excellent inertness to typically any analytes, high efficiency and compatibility with a wide range of solvents, but now can be used for wide pH analysis with consistent performance from column to column and lot to lot.
