TubeWriter provides direct-to-surface printing systems for laboratories that need to identify samples on tubes, vials, and other containers. Instead of using adhesive labels, TubeWriter prints directly onto plastic and glass labware, including microcentrifuge tubes, cryovials, HPLC vials, and conical tubes. The printed information is resistant to freezing, heating, solvents, and physical abrasion. TubeWriter is used in research, clinical, and manufacturing labs to improve sample traceability and reduce labeling errors during high-throughput workflows.
