Liquid nitrogen vesselsare designed to support long-term storage of samples 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.
Liquid Nitrogen Tanks and Styles
Liquid nitrogen tanksare manufactured in two primary styles:
- Pressurized cryogenic freezersfor long-term liquid- or vapor-phase LN2 storage
- 不n-pressurized, benchtop dewarsfor liquid nitrogen transfer.
Cryogenic freezersare designed as sample retrieval systems (with locking lids, low liquid level indicators, and audible alarms) or IATA-approved shipping vessels for global sample transport.

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 - Free-Standing Liquid Nitrogen Systems
Free-standing liquid nitrogen systems最优长期样本存储在一个吗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.

低温氮气储存系统
长期样品存储和检索系统包括与81个单元或100个单元冷冻盒兼容的机架，以最大化样品容量。某些系统包括锁定盖子，用于添加样品保护和轮式基座，以便于运输。低液位警报警告用户当需要LN2 refile时。
Shop LN2 Tanks and LN2 Containers
Low-capacity systems store less than 200 samples while high-capacity systems store more than 10,000 samples. Static holding times vary from less than 20 days to more than 300 days.

B2 - Liquid Nitrogen Transfer Vessel
台式转移船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.

B3 - Liquid Nitrogen Dry Shipper
Dry shipping vesselsmaintain cryogenic conditions for global sample transport. Select units include secure data-logging systems for 21CFR Part 11 compliance.
C - Liquid Nitrogen Vial Storage Capacity
(back to chart)
Cryogenic storage systems利用兼容81单元或100个单元冷冻盒的机架，以最大限度地提高样本容量。样品通常储存在1.5ml或2ml冷冻管或扭转帽小瓶中。低容量系统设计用于储存少于1000个样本，而大容量容器存储超过10,000个样本。
D - 液氮能力
(back to chart)
对于没有液氮递送服务的实验室，低温容器被指定为长期LN2储罐，以供应在整个实验室中使用的样品储存系统和冷陷阱。
For labspurchasing an LN2 holding tank, a critical specification is liquid nitrogen storage capacity. Low-throughput systems store fewer than 50 liters of liquid nitrogen, while high-throughput tanks store more than 200 liters.
E - 液氮静态保持时间
(back to chart)
Static holding time is the length of time listed in days, during which the cryogenic tank retains the supplied volume of liquid nitrogen. This metric, however, presumes that the container is not accessed during the stated period of time. LN2 evaporation will occur each time the cryogenic tank is opened.
Narrow-neck pressurized containersare designed to reduce LN2 evaporation rates, whereas wide-neck dewars allow for greater liquid nitrogen evaporation each time the container is opened.

F1 - Low LN2 Level Alarm for Cryogenic Tanks
Certain cryogenic tanks, such asThermo Fisher Locator Storage Systems, include ultrasonic level monitors with continuous digital LED readouts and audible/visual alarms when liquid nitrogen levels fall below set-point.

F2 - Liquid Nitrogen Rack System
Sample storage systems accommodate stainless steel and aluminum racks for easy retrieval of cryo-storage boxes. Racks are compatible with 81-cell or 100 cell boxes for 2 ml cryo-tubes or 1.5 ml twist-cap vials. Certain models offer racks compatible with 5 ml high-capacity vials.
F3 - 液氮锁定系统
For high-security sample storage, certain LN2 containers include locking lids equipped with optional padlocks, keypads or fingerprint scanners.
