液氮容器旨在支持长期储存sampl吗es at cryogenic temperatures (-196°C to -210°C). The process of cryo-preservation is widely used in clinical diagnostics, immunotherapy development, food and beverage, and semiconductor storage. Samples prepared with cryo-protectants, such as DMSO, can remain viable for up to a decade when stored in liquid nitrogen.
液氮罐和样式
液氮罐are manufactured in two primary styles:
低温冰柜are designed as sample retrieval systems (with locking lids, low liquid level indicators, and audible alarms) or IATA-approved shipping vessels for global sample transport.
A-液体氮容器设计

A1 - Benchtop
台式液氮容器are designed for point-of-use, short-term sample storage or transfer of LN2 into a shipping vessel or cold trap. Benchtop dewars store fewer than 10 liters of liquid nitrogen and do not include sample storage racks. Certain benchtop vessels include carrying handles for easy transport and vented lids to prevent over-pressurization.
A2-独立式液氮系统
独立的液氮系统are optimal for long-term sample storage within a cryogenic environment. Select models include cryo-box racks for easy sample identification, low liquid level alarms to maintain cryo-preservation conditions, and locking lids for high-security areas. High-capacity, free-standing systems are designed to store more than 10,000 samples and over 300 liters of liquid nitrogen.

B1-长期存储系统
低温药物的氮储存系统
长期样品存储和检索系统包括与81细胞或100细胞低温盒兼容的机架，以最大化样品容量。某些系统包括锁定盖，以增加样品保护和轮式底座，以方便运输。当需要LN2补充时，低液位警报警告用户。
Shop LN2 Tanks and LN2 Containers
低容量系统存储少于200个样品，而高容量系统则存储了10,000多个样品。静态存放时间从不到20天到300天不等。
B2 - Liquid Nitrogen Transfer Vessel
台式转移容器are designed to transport liquid nitrogen from a holding tank to a sample storage system or shipping vessel. Select transfer vessels are compatible with pressurized liquid withdrawal devices to prevent LN2 spillage and evaporation.
Thermo Fisher Scientific的液氮转移容器
B3-液氮干托机
Dry shipping vesselsmaintain cryogenic conditions for global sample transport. Select units include secure data-logging systems for 21CFR Part 11 compliance.
C-液体氮小瓶存储容量
（返回图表）
Cryogenic storage systems利用与81个电池或100细胞冷冻箱兼容的机架来最大化样品容量。样品通常存储在1.5 mL或2 mL的冷冻管或扭曲帽小瓶中。低容量系统旨在存储少于1,000个样品，而高容量容器存储了10,000多个样品。

F-液氮特异性特征
（返回图表）
F1 - Low LN2 Level Alarm for Cryogenic Tanks
某些低温坦克，例如热渔民定位器存储系统, include ultrasonic level monitors with continuous digital LED readouts and audible/visual alarms when liquid nitrogen levels fall below set-point.
F2-液体氮架系统
样品存储系统可容纳不锈钢和铝制架，可轻松检索冷冻储物盒。架子与81杆或100个蜂窝盒兼容，可容纳2毫升冷冻管或1.5毫升扭曲帽小瓶。某些型号提供与5毫升高容量小瓶兼容的机架。
F3-液氮锁定系统
对于高安全性样品存储，某些LN2容器包括配备可选挂锁，键盘或指纹扫描仪的锁定盖。
