For decades, cryopreservation has been used for plant cells, unfertilized (oocytes)/fertilized (zygotes) human and animal eggs, and male sperm cells. The cryopreservation process typically involves using liquid nitrogen to quickly deep freeze the cells to -196°C allowing all metabolic processes to stop, preserving them for storage, shipping, or future use.When thawed, the cells resume their normal metabolic processes. 數(shù)十年來，冷凍法一直被人們用來保存細胞卵子受精卵精子等冷凍過程是用液氮將細胞快速冷卻到-196度以便使細胞停止代謝，這樣就可以方便地進行儲存，運輸以備將來使用一旦解凍，細胞恢復代謝 制冷加熱水浴 賽默飛 SC100 - S14P 恒溫水浴 制冷加熱循環(huán)水浴AC 200-G 50 冷卻循環(huán)器小型 賽默飛 SC150L - S49 恒溫水浴 賽默飛 SC100 - S12T 恒溫水浴 賽默飛 SC150 - A25B 恒溫水浴 賽默飛 SC100 - A28 恒溫水浴 SC 100-S 6T 恒溫水浴 賽默飛 PC200 - S30 恒溫水浴 賽默飛 SC100 - A28F 恒溫水浴 賽默飛 AC200 - S7 恒溫水浴 賽默飛 PC200 - G50 恒溫水浴
