Purify complex bio-based solutions with these new resins

Lewatit PH 1074 HEP (photo) is the newest product in this company’s portfolio of ion-exchange resins for the pharmaceutical and bioprocessing industries. In addition to the decolorization of fermentation broths and sugar solutions, the new resin is particularly suited to the purification and intermediate storage of heparin. The macroporous, strongly basic anion-exchange resin, which meets food-quality standards, is based on a cross-linked polyacrylate. It has a special pore structure and resin matrix, which has been exclusively developed for the capture of high-molecular-weight compounds. Lewatit PH 1074 HEP is suitable for the treatment and purification of products derived from biomass, because it supports the reliable capture and removal of organic substances with a high molecular weight. This means that liquid sugar syrups or complex process solutions, such as fermentation broths, for example, can be purified and treated. The macroporous structure and special polymer matrix of the new Lewatit PH 1074 HEP help achieve optimum adsorption capacity and desorption properties. This is advantageous in the recovery of high-molecular-weight hydrophilic anionic organic substances. — Lanxess AG, Cologne, Germany
