Sign stands for maximum flexibility and future-proof laboratory automation.
The system reliably processes tubes and vials ranging from 0.5 ml to 50 ml – regardless of whether they are made of glass or plastic and independent of type, size, or manufacturer. This is enabled by the innovative 4-back gripper, which automatically adapts to a wide variety of containers, providing true freedom and flexibility in everyday laboratory operations.
For professional and durable identification, Sign features a high-performance labeling module with a print resolution of 600 dpi. Text, numbers, logos, linear barcodes, and QR codes are applied with exceptional clarity. Multiple import options for label designs and job data ensure fast, error-free and seamless integration into existing IT and laboratory workflows.
With a capacity of up to 12 racks, the system can process up to 1,152 tubes in a single run, depending on the rack type. Sign supports standard SBS rack formats as well as customer-specific rack configurations. This allows the system to scale with your requirements – today and in the future.

With the TwinCode barcoding system and seamless integration into ERP and LIMS environments, Sign enables controlled and standardized workflows. Designed for use in regulated laboratories, the advanced user and job management with integrated audit trail ensures maximum transparency and traceability, supporting customers in meeting compliance requirements.
