儀器介紹與應用
真空冷凍乾燥機是利用凍結與真空的技術將冷凍後的藥物或食品中的溶劑昇華，再使用水蒸氣冷凝成液態水排除，以降低濕度，達到快速乾燥之目的。
- 最低溫度: -90℃, 於室溫25℃
- 冷凝槽容量: 25公升
- 溫度顯示範圍: -100℃~50℃
- 系統真空度: 可達 4x10-1Pa (即3x103 Torr 以下)
- 連接附件口徑: 可達75 mm以上
- 真空顯示: 從大氣壓力至 1x10-1Pa 全域數位LED顯示，採用Pirani真空計

A freeze dryer (or lyophilizer) utilizes freezing and vacuum technology to sublimate the solvent from frozen pharmaceuticals or food products. The resulting water vapor is then condensed into liquid water and removed, which lowers the moisture content and achieves rapid drying.
Minimum Temperature: −90∘C, at an ambient temperature of 25∘C Condenser Capacity: 25 liters Temperature Display Range: −100∘C to 50∘C System Vacuum Level: Can reach 4×10−1 Pa (i.e., below 3×10−3 Torr) Connecting Port Diameter: Can reach 75 mm or more Vacuum Display: Full-range digital LED display from atmospheric pressure down to 1×10−1 Pa, using a Pirani vacuum gauge.
