General information

Ion Exchanger

The ion exchanger offered in our range differ depending on their application and requirements. Three different types are available:

  • Mixed bed ion exchanger
  • Cation and anion exchanger
  • Cation and anion exchanger for analytical purposes
  • Water treatment
  • Pharmaceutical industry and biochemistry
  • Production and purifying of chemicals
  • Classical laboratory analysis

ROTI®Change Ion Exchanger

Our product range ROTI®Change contains ion exchanger, which are particularly suitable for analytical purposes. The corresponding polystyrene based resins were specially purified to reduce extractable residues to less than 1 mg/g resin.

Cation exchange resins

Our cation exchange resins are available as 4 % and 8 % divinylbenzene (DVB) cross-linked polymers with sulphonate as active group. All cation exchange resins are provided in hydrogen (H+) form. Typical applications are: removal of ethidium bromide/propidium iodide from DNA samples; separation and preconcentration of amino acids, peptides and nucleotides; desalting (removal of cations) and separation of metal ions.
