Technology for critical freezing and thawing steps. Product-specific. Designed to protect.

We offer a range of equipment for controlled freezing, transport, storage and thawing of sensitive substances like proteins and other biopharmaceuticals. ZETA Freeze & Thaw Systems consist of mobile stainless-steel vessels coupled with sophisticated refrigeration systems. In addition, we offer specific laboratory and pilot scale devices to support QbD-compliant, PAT-ready development and scale-up of the freezing process.
