General description

Every bio-manufacturing process involves buffer preparation, pH adjustment, and cleaning. All our respective GMP (IPEC/EXCiPACT) products are manufactured under Excipient GMP conditions and feature low bioburden levels, backed by our Emprove® Program for exceptional quality and documentation support.
As a result, you can integrate our products directly into your biopharmaceutical production process. In addition to our comprehensive portfolio, we also offer custom manufacturing services to meet your exact needs.

Application

Sodium hydroxide pellets can be used:
  • As a raw material to prepare various buffer solutions and reagents required for cell culture, purification, and formulation steps.
  • In viral inactivation steps due to its strong denaturing properties.
  • In cleaning in place (CIP) applications as well as for pH adjustment.

Features and Benefits

  • Comprehensive, up-to-date documentation you need to navigate regulatory challenges, manage risks, and improve processes.
  • Suitable for higher-risk applications where the lowest microbiological and endotoxin levels are of utmost importance.
  • Emprove® products are designed to facilitate compliance with global regulations (e.g., ICH Q7, EU GMP, USP, EP).
  • Detailed supply chain and manufacturing information helps ensure traceability and continuity, which is critical for GMP manufacturing.
