?冷凍干燥機(jī)是將含水物品預(yù)先凍結(jié)，然后將其水分在真空狀態(tài)下升華而獲得干燥物品的一種技術(shù)方法。經(jīng)過冷凍干燥處理的物品易于長期保存，加水后能恢復(fù)到凍干前的狀態(tài)并保持原有的生化特性及物質(zhì)結(jié)構(gòu)。對(duì)于熱敏物質(zhì)如抗菌素、疫苗、血液制品、酶激素和其它生物制品，冷凍干燥技術(shù)更能顯示其優(yōu)越性。

??田楓FD實(shí)驗(yàn)室真空冷凍干燥機(jī)系列采用風(fēng)冷冷凝式制冷系統(tǒng)，冷阱可作預(yù)凍，不銹鋼結(jié)構(gòu)，透明干燥室，便于觀察冷凍干燥的全過程。
