What is Freeze-Drying Used for?

Freeze-drying is a highly effective preservation and stabilization technique used across a wide range of materials, including organic, composite, and water-sensitive objects. It is commonly applied in the treatment of water-damaged books and paper, archaeological finds, artifacts affected by mold or pests, and materials impacted by floods or fire suppression.

In addition to its role in disaster recovery, our chamber is also used for rapid freezing treatments to assist with pest abatement and mold remediation as part of broader conservation efforts.

Cultural Preservation & Restoration (CPR) provides freeze-drying services to museums, historical societies, libraries, conservators, cultural resource management firms, art collectors, and government agencies.

Our chamber operates using lyophilization, a cold-vacuum dehydration process that freezes objects, lowers the surrounding pressure, and removes moisture through sublimation. This method avoids heat-related distortion and is ideal for delicate or historically significant items.

Fees vary based on object condition, type, and treatment duration. A detailed proposal is provided after consultation.

All freeze-drying projects are conducted in a dedicated chamber to prevent cross-contamination and ensure proper treatment. Some clients use CPR solely for freeze-drying services, while others may require additional conservation support before or after treatment. We’re happy to coordinate based on your needs.
