Redesigned 2D Tubes
The innovative SAFE® 2D tubes have been thoroughly redesigned to offer top performance and user-friendliness.
Clearly identifiable racks and tubes secure your samples for decades when stored correctly.
In addition to visual differentiation through various cap colors, the tube features fixed coding, space for individual coding, and space for your logo/study project or similar. The tube coding ensures that your samples are triply secured and can be identified both visually (HR code) and by using the appropriate SAFE® readers (2D/1D code).

The LVL Tube Laser Marker TLM 864:
Although the automation-friendly Data-Matrix code on the bottom of storage tubes has been standard for many years—and has greatly simplified sample handling—many users want to mark the tubes with their specific information. At the same time, they want to move away from time-consuming and unreliable labeling methods.
For this need, LVL has developed a fully automatic tube laser marker. The TLM 864 can automatically laser-mark SAFE® tubes in SBS 96, SBS 48, and SBS 24 formats from two sides and link the information in a database with the 2D code previously lasered during production. Up to 500 tubes per hour can be coded from nine SBS/ANSI positions.
