Specialty chemicals company LANXESS is extending its portfolio to include the new Lewatit PH 1074 HEP, designed for the decolorisation of fermentation broths and sugar and the purification and intermediate storage of heparin.

The new Lewatit PH 1074 HEP can be used in the bioprocess and pharmaceutical industries. It is a macroporous, strongly basic anion exchange resin that meets food quality standards and is based on a cross-linked polyacrylate.

It has a special pore structure and resin matrix, developed for the capture of highly molecular compounds. Lewatit PH 1074 HEP is suitable for the treatment and purification of products derived from biomass, as 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.

Sugar polymer heparin is used to prevent blood coagulation and venous thrombosis. Lewatit PH 1074 HEP helps extract the heparin from this complex mixture and purify it. The ion exchanger can also be used to stabilise the heparin for transport and storage.
