Working Principle

Freeze-dehydration (lyophilization) involves three core stages:

Freezing: Materials are rapidly cooled below their triple point, forming stable ice crystals.

Primary Drying (Sublimation): Under high vacuum (typically <0.1 mbar), ice directly sublimates into water vapor, which is condensed by a cold trap.

Secondary Drying (Desorption): Bound moisture is removed by raising the temperature, ensuring residual moisture is below 1–4%.
This process preserves cellular structure, making it superior to traditional drying methods for heat-sensitive items.

Features

Compact & Durable:

Stainless steel chamber with double-seal door ensures airtightness and corrosion resistance; small footprint suits lab or workshop spaces.

Intelligent Control:
