Refurbishment and Testing Process
At American Instrument Exchange, each refurbished cryogenic storage system is inspected and evaluated by our technicians prior to shipment. Testing procedures may include controller operation verification, display functionality testing, alarm system evaluation, lid and seal inspection, physical vessel inspection, monitoring system assessment, and general operational testing. Components showing excessive wear are addressed as needed to help ensure reliable operation. Final cleaning and inspection are completed before packaging and shipment.
Shipping and Installation Considerations
The Thermo CryoPlus 2 should be installed in a well-ventilated area suitable for liquid nitrogen storage applications. Buyers should verify facility requirements for liquid nitrogen supply, oxygen monitoring systems where applicable, and safe handling procedures for cryogenic materials. Adequate space should be provided around the unit for sample access and routine maintenance. The vessel should be transported and installed in accordance with accepted cryogenic equipment handling practices.

The Thermo CryoPlus 2 is a liquid nitrogen (LN₂) cryogenic storage system designed for long-term preservation of biological samples at ultra-low temperatures. It is commonly used in research laboratories, biobanks, clinical labs, and pharmaceutical facilities to store materials such as cell cultures, stem cells, tissue samples, and DNA libraries.
The system uses liquid nitrogen to maintain extremely cold conditions in either liquid phase or vapor phase storage, helping preserve biological integrity for extended periods.
How does the CryoPlus 2 maintain ultra-low temperatures?
The system maintains cryogenic temperatures using liquid nitrogen stored inside a vacuum-insulated stainless-steel chamber. The LN₂ gradually evaporates, keeping the internal environment extremely cold.
The CryoPlus series includes microprocessor-controlled autofill capability, which automatically replenishes liquid nitrogen from a supply tank when levels drop below preset thresholds.
This automated refill system helps maintain consistent storage temperatures while reducing manual maintenance.
What types of samples are typically stored in the CryoPlus 2?
The CryoPlus 2 is commonly used to store a wide variety of cryogenically preserved materials, including:
Mammalian and bacterial cell lines
Stem cells and primary cells
Tissue samples and biopsies
Blood and serum samples
DNA, RNA, and other biological reagents
Cryogenic storage systems like the CryoPlus 2 are especially important for long-term sample preservation in biobanking and molecular biology research.
What advantages do the CryoPlus 2 and other autofill systems offer compared with manual LN₂ storage tanks?
Compared with traditional manual-fill cryogenic tanks, the CryoPlus 2 provides several operational advantages:
Automated liquid nitrogen refill system
Continuous electronic monitoring of temperature and nitrogen levels
Remote alarm capability for lab safety
Large, organized storage capacity with rack systems
Improved workflow for high-volume sample storage
These features make the CryoPlus series suitable for laboratories that require reliable long-term cryogenic storage with minimal manual intervention.
What is the difference between liquid phase and vapor phase cryogenic storage?
Cryogenic storage systems can store samples in either liquid nitrogen (liquid phase) or nitrogen vapor (vapor phase).
Liquid phase storage
Samples are immersed directly in liquid nitrogen
Provides the lowest possible temperature (-196 °C)
Vapor phase storage
Samples are stored above the liquid nitrogen surface
Maintains temperatures typically below -150 °C
Reduces risk of cross-contamination between samples
Many laboratories prefer vapor-phase storage for clinical samples and biobanking applications.
What is LN₂ evaporation rate in cryogenic storage tanks?
Evaporation rate refers to how quickly liquid nitrogen naturally boils off from a storage vessel.
Typical evaporation rates range from 2 to 10 liters per day depending on:
Tank size and insulation quality
Ambient laboratory temperature
Frequency of lid openings
Amount of stored material
Lower evaporation rates indicate more efficient cryogenic insulation.
Can LN₂ storage tanks be connected to remote monitoring systems?
Many modern cryogenic storage systems include remote alarm contacts and monitoring capabilities.
These features allow laboratories to:
Monitor temperature and nitrogen levels remotely
Receive alerts for low nitrogen levels or system issues
