Beschreibung

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 (NaOH) is an inorganic highly caustic metallic base and can readily absorb moisture in the air. It can be used:

• As a base for preparing various process buffers.
• To adjust the pH of process solutions, buffers, and media.
• As a CIP solution to clean stainless-steel tanks and piping systems, to wash and store chromatography resins, and to regenerate membranes.

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.
