Supplier: HAMILTON BONADUZ

PRP-h5 polimeric reversed phase columns are ideal for applications that require a high degree of column-to-column and batch to batch consistency (quality assurance, clinical trials). Unlike C8 or C18 columns, PRP-h5 has no stationary phase coating. The integral reversed phase characteristics of the PRP-h5 column eliminate the need for special coating techniques. Since there is no stationary phase to hydrolyse, the column maintains its performance characteristics longer than many C8 or C18 columns. PRP-h5 columns are packed with a poly(styrene-divinylbenzene) material.
