Symmetry Series
Exceed the standards for an HPLC Column

Symmetry® LC Columns are manufactured using high purity silica and tightly controlled manufacturing processes to ensure that you receive a column that exceeds the standards for HPLC column performance.  No other silica-based LC column brand can match the column-to-column and batch-to-batch reproducibility of the Symmetry family.
