Efficient and Safe Biobanking Solution: Smart Large-Capacity Vapor Phase Liquid Nitrogen Tank

This model of vapor phase liquid nitrogen tank is designed for the long-term active preservation of vaccines, microbial cultures, cells, as well as human and animal organs and samples.

1. Key Technical Specifications:

· Storage Modes: Compatible with both vapor phase and liquid phase storage.

· Internal Volume: ≥1750L.

· Storage Capacity: Can hold over 93,000 2ml cryovials.

· Design Features: Utilizes vacuum insulation and offset tubing design, with a total capacity of 1770L. Below the cryovial rack platform, the liquid nitrogen capacity is ≥296L. In vapor phase storage, it maintains an internal temperature below -185°C, ensuring long-term preservation of biological samples while minimizing liquid nitrogen consumption.

· Temperature Monitoring: Equipped with two platinum probes to monitor internal temperatures in real-time, displaying both the temperature beneath the lid and inside the tank with an accuracy of ±1.0°C. Users can set custom temperature alarms to monitor maximum and minimum temperatures.

· Liquid Level Measurement: Features a differential pressure measurement system at the bottom of the rotating disk with an accuracy of ±13mm and a resolution of 2.5mm. This system offers more precise liquid level detection compared to traditional sensors.

· Hot Gas Bypass Control: Before initiating liquid nitrogen filling, the system redirects warmed nitrogen gas from the tank and piping to the environment until the desired temperature is reached, reducing additional liquid nitrogen consumption.

· Structural Design: Includes a dual-layer, foldable step design that lowers the standing position relative to the tank opening, making sample retrieval easier and safer.

· Control System: Operated by an intelligent microprocessor controller with a large LCD screen displaying real-time maximum and minimum temperatures, liquid levels, and daily liquid nitrogen consumption. The controller has a password lock to prevent unauthorized parameter changes.

· Defogging Function: A one-touch defogging feature allows for quick sample retrieval.

· Data Interface: Equipped with two RS485 data output interfaces and a remote alarm output, enabling data collection and system monitoring. Multiple tanks can be linked through the RS485 interface for synchronized control, parameter adjustments, and automatic liquid nitrogen filling.

Third-Party Probe Compatibility: A dedicated interface for third-party monitoring probes is available on the outside of the tank.

· Certification Standards: Compliant with CE certification standards.

• Wireless Monitoring Module and Remote Alarm System:

· Functional Features: Provides real-time temperature monitoring and remote alarm capabilities.

Wireless Transmission: Utilizes the 434MHz frequency band for scientific/medical equipment in China, with a transmission range of up to 400 meters indoors and 700 meters in open outdoor areas. (Proof required)

· Compliance Certification: Meets standards such as FDA 21 CFR Part 11, ISO 17025, and cGxP, with optional IQ/OQ certification services. (Proof required)

· Receiver Configuration: Offers USB and TCP/IP interfaces, supporting up to 50 receivers per system, with each receiver capable of managing up to 50 monitoring modules.

· Independent Monitoring Module: Features an LCD screen displaying current readings, battery life, and signal strength. The built-in memory can store up to 3,000 data points, which can be synced to software on a schedule or manually to prevent data loss during communication disruptions or power outages.

· Monitoring Range and Power: The temperature monitoring range is -100°C to +150°C; powered by an internal lithium battery with a lifespan of over 1 year.

· Monitoring Software: Includes features for data collection, alarm threshold adjustments, permission settings, data charting, and user permissions management. Monitoring data can be exported in Word, Excel, or PDF formats.

· Alarm System: Supports various alarm methods, including on-site alarms (sound, light, print reports) and remote alarms (phone, email, fax notifications).

· Temperature Monitoring Workstation: Includes two workstations equipped with Intel Core i7 CPUs, 8GB of memory, 1TB hard drives, 22-inch HD monitors, and color printers for real-time printing of temperature monitoring reports.
