custom synthesis of a wide variety of resorbable polymers in addition to our PURASORB product line. Purac Biomaterials offers design, (co)-

development and ICHQ7 compliant commercial scale production of PURASORB resorbable polymers.

Capabilities We offer custom synthesis within our current capabilities. These capabilities

include: • Homopolymers and co-polymers of lactide (L,D,DL), glycolide and/ or

ε-caprolactone. • Various end group chemistries & catalysts

• Different polymerization technologies & purification • Molecular weights ranging from a few thousand to several

million g/mol (inherent viscosity up to 8 dl/g). • ICHQ7 compliant batch sizes from 5 kg up to 100 kg and larger.

• GLP batch sizes up to 1.5 kg. • Custom designed specifications and Certificates of Analysis.

• Analytical services

We offer co-development and contract manufacturing of custom polymers

outside these capabilities under customer specific agreements.

Lead time The lead time for a custom-synthesized GMP batch varies between 6 and 26

weeks, depending on your requirements.

We can also supply new polymer compositions in small scale batches manufactured under GLP conditions for your initial evaluation. Lead times are

4 to 8 weeks.
