SAFE® TLM FAQ –
Tube Laser Marker for Permanent Tube Labeling
The SAFE® Tube Laser Marker TLM 864 from LVL technologies is a fully automated system for permanent laser marking of 2D tubes in SBS format. This FAQ section answers key questions about functionality, marking performance, supported SBS formats, data integration, traceability, and cryo-stability of the material-integrated tube labeling.
The SAFE® TLM complements the existing 2D DataMatrix code with additional visual information such as text, study codes, internal IDs, or symbols. The original tube ID remains unchanged. Unlike labels, the marking is directly engraved into the material and remains fully legible even under cryogenic conditions down to −196 °C.
Especially in biobanking, clinical trials, pharmaceutical research, and regulated laboratory environments, the SAFE® Tube Laser Marker ensures reliable integration of machine-readable identification, visual verification, and digitally traceable sample management.
Basics & Functionality
The TLM 864 is an automated laser system for lateral or additional marking of 2D tubes.
It supplements existing 2D DataMatrix codes with additional information such as:
- Text
- Study codes
- Internal identification numbers
- Symbols
The original 2D ID on the tube bottom remains unchanged.
The 2D DataMatrix code primarily serves machine-readable identification.
Additional laser marking provides visual identification in daily laboratory workflows.
This is particularly useful for:
- Manual interim steps
- Rack transfers
- Visual verification during workflow
The laser engraving is permanently integrated into the material and not applied as a surface label.
No.
The laser process adds markings laterally or additionally without altering the 2D DataMatrix code at the tube bottom.
The unique tube ID remains fully intact.
Technical Specifications
The TLM 864 supports SAFE® 2D tubes in SBS formats 24, 48, and 96.
This enables integration into existing rack and automation workflows.
The TLM 864 can mark up to 500 tubes per hour.
It is suitable for medium- to high-volume applications in biobanking and pharmaceutical research.
The system has multiple insertion positions (up to nine), supporting continuous workflow.
Labeling data can, for example, be imported via CSV files.
This allows structured data transfer from LIMS or database systems.
Traceability & Data Integration
The TLM 864 enables the assignment of additionally laser-engraved information to the existing 2D ID.
This creates a consistent data trail without requiring a separate identification logic.
The material-integrated laser marking is permanent and abrasion-resistant.
Combined with LIMS integration, this supports traceable and consistent documentation in regulated environments.
Laser marking is:
- Material-integrated
- Abrasion-resistant
- Resistant to condensation
- Cryo-stable down to −196 °C
Unlike labels, it does not peel, bubble, or become brittle under cold or humid conditions.
Workflow & Automation
The TLM is designed as a stand-alone system but can be integrated into structured laboratory workflows.
SBS standardization of the tubes facilitates integration into existing infrastructure.
The Tube Laser Marker is suitable for:
- Biobanking
- Clinical studies
- Pharmaceutical research
- Applications requiring additional visual marking
It is especially relevant when permanent visual marking is needed alongside machine-readable identification.
Permanent marking reduces the risk of sample mix-ups during manual processes.
Combining 2D DataMatrix codes with laser marking links machine-readable and visual identification.
Yes.
The laser engraving is directly integrated into the material and remains stable and legible even at −196 °C.
No delamination or peeling occurs.
