Rethinking Freeze & Thaw in Biopharmaceutical Manufacturing
Why Freeze & Thaw Matters
Freeze and thaw systems serve as an important link between manufacturing operations, storage, and distribution. These processes allow manufacturers to safely store valuable intermediates, decouple production steps, and support flexible manufacturing strategies across multiple facilities.
However, freezing and thawing biological products presents unique challenges. Temperature gradients, cryoconcentration, protein aggregation, and other physical changes can impact product quality if not carefully controlled. Reliable process design and appropriate equipment selection are therefore essential to ensuring consistent performance at both development and commercial scale.
Innovation from the ZETA TechCenter
At the ZETA TechCenter, research teams work closely with process engineers and customers to develop practical solutions to real-world manufacturing challenges. Recent projects demonstrate how freeze and thaw technology continues to evolve.
Water-Free Thawing
One of the latest innovations is a water-free thawing system that uses stainless steel beads as heat transfer media instead of traditional water baths.
This approach enables gentle and uniform thawing across a variety of packaging formats, including stainless steel containers, glass vessels, and single-use bags. Pilot studies have demonstrated consistent heat transfer performance while reducing some of the operational challenges associated with conventional water-based thawing systems.
Air-Based Freezing
ZETA is also evaluating a next-generation freeze system that uses air as the sole refrigerant, eliminating the need for natural or synthetic cooling gases.
The goal is to develop a future-ready solution that supports evolving environmental regulations while maintaining the process performance required for biopharmaceutical manufacturing. Initial testing has demonstrated promising results, and ongoing validation activities are helping further refine the technology.
From Research to GMP Manufacturing
Innovation is only valuable when it can be applied in real manufacturing environments. ZETA’s freeze and thaw portfolio combines scientific process understanding with scalable equipment solutions that support development, pilot, and commercial production.
The portfolio includes:
