The Thermo Scientific CryoPlus 1 is part of the CryoPlus 7400 Series of automated liquid nitrogen storage systems. Designed for laboratories requiring dependable cryogenic preservation, the CryoPlus 1 provides a compact alternative to larger LN2 storage vessels while offering automated liquid nitrogen management and electronic monitoring.
The Model 7400 features a 90-liter vacuum-insulated storage chamber that minimizes heat transfer between the surrounding laboratory environment and the cryogenic interior. Its stainless steel construction provides a durable storage vessel designed for repeated laboratory use.
The system's automatic liquid nitrogen refill function is a major advantage over manually filled cryogenic storage containers. When connected to an appropriate external liquid nitrogen supply, the CryoPlus 1 monitors the LN2 level and controls replenishment to maintain the selected operating level.
This reduces the need for routine manual filling and helps laboratories maintain more consistent cryogenic storage conditions.
A microprocessor controller provides access to operating parameters and liquid nitrogen level settings. Visual level indicators allow personnel to monitor system status, while alarm functions help identify abnormal operating conditions that may require attention.
The CryoPlus 1 is particularly useful for laboratories that need automated cryogenic storage but do not require the much larger capacity of the CryoPlus 2, CryoPlus 3, or CryoPlus 4 systems.
The Thermo Scientific CryoPlus 1 supports long-term cryogenic preservation of compatible biological materials, including mammalian cell lines, stem cells, hybridomas, microbial cultures, research cell banks, tissue specimens, and other materials requiring storage at liquid nitrogen temperatures.
Cryogenic preservation is frequently used in cell biology, biotechnology, pharmaceutical research, regenerative medicine, molecular biology, microbiology, reproductive research, and biobanking.
For many cell-based applications, cryogenic storage at temperatures below approximately -130°C helps reduce molecular activity and biological deterioration during long-term preservation. Actual storage requirements depend on the sample type, cryoprotectant, storage container, and validated preservation protocol.
The CryoPlus 1 can also serve as the long-term storage component of a broader cryopreservation workflow. Samples may first be prepared and frozen using a controlled-rate freezer before being transferred into an appropriate cryogenic storage system.
The CryoPlus 1 is well suited for biotechnology companies, pharmaceutical research facilities, academic research institutions, cell culture laboratories, biomedical research centers, cell banking operations, biobanks, and specialized clinical research facilities.
Its relatively compact dimensions make it particularly attractive for laboratories with limited available floor space or facilities that need a dedicated cryogenic storage system for a specific research program.
The automated liquid nitrogen management system can also benefit laboratories seeking to reduce routine manual filling and improve consistency in cryogenic storage operations.
Facilities working with valuable biological specimens should evaluate the CryoPlus 1 as part of a complete preservation strategy that includes appropriate monitoring, liquid nitrogen supply management, sample inventory controls, and emergency procedures.
The Thermo Scientific CryoPlus 1 maintains cryogenic conditions through the controlled use of liquid nitrogen rather than a mechanical compressor-based refrigeration system.
The vacuum-insulated stainless steel chamber reduces heat transfer into the storage vessel, helping limit nitrogen evaporation and maintain the extremely low temperatures necessary for cryogenic preservation.
The system's microprocessor controller monitors liquid nitrogen levels and activates the automatic refill system when replenishment is required. Maintaining appropriate LN2 levels is essential for reliable cryogenic storage.
Thermo Scientific specifies a manufacturer-rated static evaporation rate of approximately 3 liters per day for the CryoPlus 1. This rating is measured under controlled static conditions and does not represent guaranteed consumption during normal laboratory use.
Actual liquid nitrogen consumption will depend on lid-opening frequency, sample loading, ambient conditions, storage configuration, transfer-line performance, and the condition of the vacuum-insulated vessel.
The manufacturer also specifies a theoretical static holding time of approximately 30 days. This figure should not be interpreted as a guaranteed unattended storage period or a substitute for continuous liquid nitrogen supply and monitoring.
The CryoPlus 1 supports both vapor-phase and liquid-phase storage arrangements. Vapor-phase storage can reduce direct contact between specimens and liquid nitrogen, while liquid-phase storage provides immersion in LN2. The appropriate configuration depends on the sample, container design, and laboratory protocol.
The CryoPlus 1 provides storage for up to 6,318 standard 2 mL cryovials when equipped with the appropriate inventory system.
For efficient sample management, laboratories should organize cryovials using compatible cryogenic racks, boxes, and inventory identifiers. Storage locations can be assigned according to project, cell line, sample type, collection date, or research group.
Because cryogenic storage systems operate at extremely low temperatures, sample retrieval procedures should be designed to minimize unnecessary lid openings and exposure of stored materials to warmer conditions.
Cryogenic vials and storage containers must be specifically rated for the intended liquid nitrogen storage configuration. Laboratories should verify whether their sample containers are appropriate for vapor-phase storage, liquid-phase immersion, or both.
Sample identification systems should remain readable and secure under cryogenic conditions. Cryogenic labels, compatible rack systems, and electronic inventory records can help reduce retrieval errors.
For valuable or irreplaceable specimens, laboratories should maintain appropriate liquid nitrogen supply arrangements, alarm-response procedures, backup cryogenic storage capacity, and documented emergency sample-transfer plans.

Specifications are based on Thermo Scientific's published CryoPlus 7400 Series literature. Cryovial capacity depends on the installed rack configuration, and liquid nitrogen consumption varies with actual operating conditions. Included racks, transfer hoses, and accessories should be confirmed before purchase.
Unlike compressor-based ultra-low temperature freezers, the Thermo Scientific CryoPlus 1 relies on liquid nitrogen to maintain cryogenic storage conditions.
Its vacuum-insulated stainless steel chamber helps reduce heat transfer and minimize LN2 evaporation, while the automatic refill system maintains the selected liquid nitrogen level when connected to an appropriate external supply.
Thermo Scientific reports a static evaporation rate of approximately 3 liters per day for the CryoPlus 1 under controlled test conditions.
Actual consumption may be higher during routine operation, particularly when the lid is opened frequently or when warm samples and storage accessories are introduced into the chamber.
Operating costs are therefore influenced primarily by liquid nitrogen consumption, local LN2 pricing, delivery arrangements, supply-tank rental, and laboratory usage patterns.
Electrical requirements are comparatively modest because the system uses electricity primarily for monitoring, control, and automated liquid nitrogen management rather than compressor-driven refrigeration.
Laboratories comparing cryogenic storage systems should evaluate both acquisition cost and the ongoing cost of liquid nitrogen supply, storage infrastructure, maintenance, monitoring, and facility safety requirements.
This Thermo Scientific CryoPlus 1 Model 7400 liquid nitrogen storage system is supplied used and refurbished by American Instrument Exchange.
