Intelligent LN2 Bio-Bank

The Intelligent Liquid Nitrogen Storage System serves as the core of the platform, providing a stable, low-temperature environment for the preservation of high-value biological samples such as cells, tissues, stem cells, blood samples, genetic materials, vaccines, and clinical specimens.

For enhanced accuracy and full traceability in cryogenic biobanking operations, the system integrates two major subsystems:

● Biological Sample Preservation Information Management Subsystem

• Tracks the full life cycle of every sample

• Ensures real-time monitoring of storage conditions

• Supports barcode/RFID identification, batch management, and sample location mapping

• Enables strict quality control and compliance with international biobanking standards (ISO 20387)

● Biological Sample Operation Management Subsystem

• Standardizes sample access, registration, transfer, retrieval, and return

• Ensures error-free sample handling through guided workflows

• Provides audit trails and operator permissions for secure biobank management

• Improves efficiency in large-scale biobank operations

The storage solution can be configured as vapor-phase LN2 storage for contamination prevention or full-liquid LN2 storage for ultra-low temperature requirements.
This flexible design meets the diverse needs of clinical biobanks, gene banks, IVF centers, stem cell banks, and more.

The Automatic Liquid Nitrogen Refilling System ensures an uninterrupted and stable cryogenic environment—critical for long-term sample preservation and avoiding temperature fluctuations caused by manual operations.

To achieve secure and continuous automated refilling, the system integrates three high-precision technologies:

● Liquid Level Monitoring System

• Real-time LN2 level measurement with high-accuracy sensors

• Prevents overfilling or depletion

• Supports multi-point monitoring and alarm notifications

● Automatic Refilling System

• Fully automated LN2 replenishment without manual intervention

• Ensures consistent and reliable LN2 supply for all cryogenic tanks

• Compatible with centralized LN2 supply pipelines or external LN2 tanks

● Intelligent Algorithm System

• Predictive refilling based on consumption patterns

• Optimizes LN2 usage to reduce operational costs

• Ensures stable cryogenic temperature across large-scale biobank storage

This automated system is essential for large biobanks, ensuring a safe, hands-free LN2 supply and supporting 24/7 continuous cryogenic preservation.

To ensure complete traceability and systematic management of biological samples, SERLNG provides a fully integrated Biobanking Information Management System, designed to meet modern biobank digitalization needs.

It includes two critical subsystems:

● Biological Sample Preservation Information Management Subsystem

• Records preservation conditions, storage time, and LN2 tank parameters

• Supports intelligent sample positioning and quick retrieval

• Ensures compliance with traceability and regulatory requirements

● Biological Sample Operation Management Subsystem

• Manages sample intake, retrieval, transfer, and disposal

• Provides permission control and operational logs

• Enhances workflow automation and minimizes human error

This information management system ensures end-to-end traceability, data integrity, and accurate sample tracking, forming the digital backbone of an intelligent LN2 biobank.
