Why Automated Sample Management Systems Have Special Requirements for Labels
With the rapid growth in biobank scale and rising laboratory automation levels, automated sample management systems (ASMS) have become standard equipment for large biopharmaceutical companies and medical research institutions. These systems integrate automated cold storage, robotic tube-picking systems, automated barcode scanning devices, and sample management software, enabling sample storage and retrieval, inventory counting, data entry, and location management under unattended conditions.
However, automated systems place far stricter requirements on labels than manual operation. BradyLAB BRD LN₂ labels have been verified for compatibility with multiple mainstream automated sample management platforms, meeting the strict specifications of automated equipment in terms of label dimensional accuracy, barcode contrast, surface flatness, and low-temperature performance. BradyLAB BRD labels help laboratories achieve a fully automated closed loop in sample management, significantly reducing manual errors and improving sample storage and retrieval efficiency.
Data Integration Between LIMS and BradyLAB BRD Labels
The laboratory information management system (LIMS) is the core data management platform of the modern laboratory. The coding system of BradyLAB BRD labels integrates seamlessly with mainstream LIMS platforms, supporting the following data integration methods:
Built-in encoding logic in label templates: BradyLAB BRD provides templates compatible with label design software such as Brady Codesoft, BarTender, and Nicelabel. Users can directly call fields such as sample number, storage location, and collection date from the LIMS within the templates, enabling batch printing and automatic data population. BradyLAB BRD label templates support 1D barcodes, 2D codes, and multi-code combinations, allowing a single label to carry both human-readable information and machine-readable codes.
API data interface integration: For customized LIMS, BradyLAB BRD provides REST API documentation, enabling the LIMS to directly invoke label printing commands, covering the full automated data flow from sample registration → label printing → scan-based storage → storage/retrieval records → disposal.
CSV batch import: BradyLAB BRD label printing software supports CSV/Excel batch import of sample information, generating hundreds of labels with one click—ideal for initial database creation and periodic inventory counting in large biobanks.
Automated Equipment Compatibility Verification
The BradyLAB BRD technical team has completed full compatibility testing on mainstream automated sample management platforms:
Hamilton BiOS automated cold storage: BradyLAB BRD labels completed 2,000 robotic tube-picking cycles in a Hamilton BiOS -80 °C automated cold storage system. Labels showed no wear and no displacement, with a barcode recognition success rate of 100%. Label surface flatness deviation ≤ 0.02 mm, meeting the precise positioning requirements of robotic vacuum suction heads.
Brooks BioStore automated LN₂ system: In a Brooks BioStore -196 °C automated LN₂ storage system, BradyLAB BRD labels completed 500 storage/retrieval cycles. Labels maintained complete adhesion in the LN₂ gas-phase environment (approximately -190 °C), and barcodes were immediately readable under the robotic system's built-in scanner.
Thermo Fisher ALS automated tube-picking system: BradyLAB BRD labels are compatible with the Thermo ALS series automated tube-picking systems, with label dimensions and positioning deviation controlled within ±0.1 mm, ensuring precise operation of the automated tube-picking robot.
Key Performance Indicators of BradyLAB BRD Labels in Automated Systems
To ensure label reliability in automated sample management systems, BradyLAB BRD performs factory testing of the following key indicators on every batch of labels:
Dimensional accuracy: Label cutting accuracy ±0.1 mm, ensuring precise matching with automated labeling machines and scanning equipment. For SBS-standard cryovials, BradyLAB BRD offers full-wrap and half-wrap specifications to match the rack designs of different automated storage and retrieval systems.
Barcode readability: Printed barcode quality grade ≥ ANSI/ISO Grade B (factory standard), barcode contrast (PCS value) ≥ 90%. After LN₂ storage, barcode grade degradation ≤ 1 grade, still meeting the reading threshold of automated scanning equipment.
Surface flatness: Surface flatness deviation after label application ≤ 0.02 mm (measured with a 3D optical profilometer). This indicator is critical for vacuum-adsorption tube picking by automated robotic arms—a raised label edge can cause suction failure and dropped tubes.
Overall Advantages of BradyLAB BRD Automated Labeling Solutions
Compared with imported brand labels, BradyLAB BRD offers significant overall advantages in automated sample management systems. BradyLAB BRD labels have short lead times—standard models can be produced and shipped within 24 hours of order receipt, eliminating the 8–12 week lead time bottleneck of imported brands that constrains laboratory timelines. BradyLAB BRD provides free automated system compatibility testing—customers can mail in sample tubes and cryovial samples, and the BradyLAB BRD technical team will complete label compatibility testing in a simulated automated environment and issue a compatibility report.
In terms of cost, BradyLAB BRD label prices are only 40%–60% of comparable imported products. For large biobanks managing tens of thousands to hundreds of thousands of samples, annual label expenditure can be significantly reduced. BradyLAB BRD also offers custom label sizing, free from the standard specifications of imported brands, fully matching the rack and fixture designs of existing laboratory automated equipment.
Automated sample management is an inevitable trend in laboratory development, and a reliable, precise, and traceable sample identification system is the foundation of automation success. BradyLAB BRD LN₂ labels, with verified automation compatibility and full-process technical service, help laboratories achieve truly unmanned sample management.

FAQ
Q: How are labels integrated with automated sample management systems?
Through unified coding rules, label barcodes correspond one-to-one with system database fields, and together with automated scanning equipment, automatic identification of sample check-in and check-out is achieved.
Q: What additional requirements does automated management place on labels?
Barcodes must meet the readability requirements of high-speed machine scanning, preferably Grade B or above per ISO/IEC 15416, and label positions must be standardized and consistent.
Q: How should a labeling solution for an unmanned biobank be designed?
Use a layered identification approach of "box-level RFID + tube-level barcode," combined with automated robotic arms and scanning stations, to achieve full-process unmanned tracking.
LN₂ Label Integration with Automated Systems
Automated sample management systems (such as automated cold storage and robotic storage/retrieval) place higher demands on label positioning accuracy and barcode readability: labels must be applied at fixed positions with consistent barcode orientation to facilitate machine vision recognition. For batch reading scenarios, RFID can be introduced to enable rapid whole-box inventory counting.
Efficiency Gains from Integration
Once labels are integrated with automated systems, sample storage and retrieval upgrade from manual searching to system-based positioning, improving inventory counting efficiency by orders of magnitude. Combined with LIMS, real-time sample location mapping, automatic check-in/check-out records, and exception alerts can be achieved, greatly reducing manual errors.
