Biobanks are entrusted with the critical mission of long-term preservation and standardized management of precious specimens. As the foundation of specimen information traceability, specimen labeling directly affects the accuracy and safety of sample management. With their outstanding performance, BRD BradyLAB LAB series cryogenic labels have become the first choice of many biobanks.
1. Adaptability to Extreme Low-Temperature Environments
Common preservation methods in biobanks include -80 °C ULT freezers and -196 °C liquid nitrogen. In low-temperature environments, ordinary labels are prone to adhesive failure, face stock embrittlement, and information loss. Through special material formulations and process treatment, BRD BradyLAB LAB series cryogenic labels maintain stable adhesion and information legibility under extreme low temperatures.
2. Multiple Materials and Specifications Available
Based on different specimen containers and management requirements, BRD BradyLAB offers cryogenic labels in a variety of materials including polyester (PET), polypropylene (PP), and nylon (Nylon), as well as multiple sizes, colors, and shapes, meeting the labeling needs of microcentrifuge tubes, cryovials, microplates, reagent bottles, and other containers.
3. Printing and Identification Compatibility
The labels are compatible with thermal-transfer, laser, and other printing methods, and support barcodes, 2D codes, RFID, and other information carriers, facilitating integration with LIMS and sample management systems for full specimen lifecycle traceability.
4. Balance of Quality and Cost
While ensuring performance, BRD BradyLAB LAB series cryogenic labels effectively reduce customer procurement costs through a domestic supply chain and large-scale production, making them a high-quality alternative to imported labels.
5. Localized Service Response
Compared with imported brands, BRD BradyLAB can provide faster response for sample testing, technical support, and custom services, helping customers quickly resolve practical application issues.
Related Compliance Standards
The selection of biobank cryogenic labels should meet the requirements of ISO 20387:2018 for specimen identification traceability and durability. Label barcode quality shall be implemented with reference to ISO/IEC 15416 (1D) and ISO/IEC 15415 (2D).

FAQ
Q: What key indicators should be considered when selecting cryogenic labels for a biobank?
Four key indicators: low-temperature range, low-temperature holding adhesion of the adhesive, barcode readability (after frosting), and chemical resistance.
Q: What grade should biobank label barcodes achieve?
1D barcodes are recommended to achieve ISO/IEC 15416 Grade C (1.5/10) or above, and 2D codes are recommended to achieve ISO/IEC 15415 Grade C or above, ensuring stable scanning after long-term cryopreservation.
Q: Are there differences between cryovial and cryobox labels?
Yes. Cryovial labels are small and applied to curved surfaces, requiring liquid nitrogen resistance; cryobox labels have a larger flat surface, with emphasis on batch printing efficiency and information capacity. The adhesive requirements are the same for both.
Cryogenic Label Selection Quick Reference
When selecting cryogenic labels, it is recommended to answer four questions first, then use the table below to quickly identify the appropriate solution.
| Decision Question | Option | Corresponding Selection |
|---|---|---|
| Storage temperature? | Liquid nitrogen -196 °C | Polyimide PI face stock + low Tg adhesive |
| Storage temperature? | -80 °C ULT | Polyester PET face stock + cryogenic adhesive |
| Application surface? | Plastic/glass/metal | Match adhesive by surface energy |
| Printing method? | Thermal transfer/laser/inkjet | Match face stock and ribbon combination |
Four Common Selection Pitfalls
Pitfall 1: Looking only at nominal temperature resistance while ignoring the match between adhesive and actual surface; Pitfall 2: Ignoring freeze–thaw cycles—the process of moving from ambient to low temperature and back is where label detachment most often occurs; Pitfall 3: Mismatching printing method and face stock, resulting in blurred or easily rubbed-off print; Pitfall 4: Bulk purchasing without actual testing, only to discover detachment or unscannable labels after cryopreservation.
Post-Selection Verification Loop
After selecting labels, it is recommended to follow a three-step process: "small-batch testing → full verification → bulk procurement." Draw 5% of samples for cryopreservation at the target temperature with freeze–thaw cycles, check detachment rate, barcode readability rate, and adhesion strength with reference to GB/T 2792-2014 and ISO/IEC 15416. Only after all criteria are met should bulk use begin, preventing specimen labeling failure risks at the source.
Complete Decision Process for Cryogenic Label Selection
Cryogenic label selection is recommended to follow a "five-step method": Step 1, clarify storage temperature and operating environment; Step 2, confirm the material and surface energy of the application surface; Step 3, determine the printing method and ribbon type; Step 4, assess whether special properties such as chemical resistance and freeze–thaw resistance are required; Step 5, conduct small-batch proofing and actual testing at the target temperature. After completing these five steps, selection risk is largely under control.
Selection Reference for Common Scenarios
| Scenario | Recommended Face Stock | Printing Recommendation |
|---|---|---|
| Liquid nitrogen cryopreservation -196 °C | Polyimide PI | Thermal transfer + resin-based ribbon |
| ULT -80 °C | Polyester PET | Thermal transfer + resin/wax-resin |
| Standard freezing -20 °C | Polyester/polypropylene | Thermal transfer + wax-resin |
| Refrigerated 2~8 °C | Synthetic paper/laminated | Thermal transfer or laser |
Balancing Cost and Performance
Selection also requires balancing cost and performance: for liquid nitrogen and ULT scenarios, reliability comes first—prioritize PI/PET; for scenarios above -20 °C, more cost-effective polypropylene or synthetic paper can be used. In the long run, the per-unit cost of labels is extremely low, while the loss from a single specimen failure far exceeds the label itself. Therefore, in critical scenarios, "prioritize reliability, do not compromise" is the wiser strategy.
Continuous Improvement After Selection
Label selection is not a one-time action. As specimen types, storage equipment, or printing systems change, label requirements may also change. It is recommended to periodically review actual label performance (detachment rate, scan success rate) and retain quality records for each label batch to provide data support for continuous improvement and change decisions.
Recording and Reviewing Selection Decisions
It is recommended to keep decision records for cryogenic label selection: operating condition description, candidate solutions, test data, and final conclusions. Periodically reviewing label performance (detachment rate, scan success rate) can provide a data basis for subsequent changes and bulk procurement, avoiding repeated trial and error based on experience alone.
