Printing Racks

Two (2) interchangeable printing racks come with each TubeWriter™ 300 Labeling Systems allowing for rapid switching between lab ware types

  • Configurable for any curved or flat lab ware surface
  • Securely holds lab ware during printing
  • An asymmetric base ensures correct alignment for printing

**Custom racks are not available for the TubeWriter 300 System. Please consider the TubeWriter 400 for custom printing needs.

FAQ - TubeWriter™ 300 Labeling System

The TubeWriter prints on almost any labware. So anything from 0.2mL PCR tubes to 50mL conicals, glass or plastic, side or top. Histology cassettes, plates and microscope slides.

With each system you get to choose four standard racks. So out of the box you can print on any four tubes. But after opening the box, you can purchase more racks for more types of tubes.

The print resolution of our tube labeler is enough for 50 characters on 1.5mL microcentrifuge tubes. Or a 2D barcode on a PCR tube. The quality is such that you can do a barcode read from the tubes.

Depending on your settings, you can print as fast as around a tube a second. In most cases you will want to tradeoff some speed for higher solvency resistance. So plan on labeling a rack of tubes in about five minutes.

Around once per year, you’ll need to service the tube labeling machine.

We find most customers are happy with a standard 2D barcode and a DataMatrix 2D barcode. But we also offer most of the other major symbologies. Please note the barcodes are available at an additional cost with the TubeWriter 300.

You can have one of our experts create a template for you. Just email what you would like where; or draw something on the back of a napkin; or send us a tube to copy.


Or you can change parameters in the software yourself.

As easy as switching paper sizes in your desktop paper printer. Just use a different rack adapter and then select that rack adapter in the pull-down on the software.

The disposable cartridges last for 90 days each.
