TubeMarker™ 2

Includes: 4 tube adaptors (see below), AC adaptor 18W 18VDC (input 100-240VAC), USB A-B cable, operation manual, software (on USB-Stick), 12 months warranty



The TubeMarker™ 2 is designed to directly print text, linear barcodes, 2D codes and graphics on plastic laboratory tubes using patent pending Thermal Pixel Printing technology.

  • Prints directly on the surface of tubes from 0.2 ml to 50 ml - Labels or stickers are not required

  • Clearer and more durable marking compared to marker pen - Consistently legible text and barcodes at high resolutions

  • Resistant to alcohol, water, liquid nitrogen and mechanical abrasion - Long lasting sample identification at competitive “per mark” cost.


There is no need for using labels or marker pens. Marking is resistant to ethanol, isopropanol, methanol, DMSO*, pure haematoxylin, water, liquid nitrogen and mechanical abrasion. The prints are also stable over a wide temperature range (-196°C to 100°C). Markings do not transfer when touching the tubes.

Several lines of text can be printed, for example sample name, sampling site, your name, date, time etc. All TrueType fonts available on the connected computer can be printed with different font types and sizes determining the maximum printed content. Bold and italic type is also possible.

The instrument also prints linear barcodes, 2D codes and graphic files (monochrome .bmp, .gif, .tiff) such as logos. Print orientation can be vertical or horizontal (except for barcodes which print vertically only). 

Printing straight to the tube surface is much easier and faster than marking by hand.

  • No more smudged, illegible writing on tubes! 

  • No more disappearing labelling after each ethanol wash step! 

  • No more fiddling with tiny labels! 

  • Clean, fuss-free and durable labelling of all common tube formats with the TubeMarker™ 2!

Instrument Features

  • Prints directly on the surface of plastic laboratory tubes - labels and stickers are not required
  • Most 0.2 ml - 50 ml volume tubes with a smooth surface can be used 
  • Both vertical and horizontal markings are possible
  • Prints text, linear barcodes, 2D codes and graphic files (monochrome .bmp, .gif or .tiff) such as logos
  • Labels printed in seconds
  • Easy import of data from Microsoft® Excel files
  • Tube profiles created in the TubeMarker™ 2 software can be saved for future reference

Printing Quality

  • Clearer and more durable marking compared to marker pen
  • Marking is resistant to ethanol (70%), isopropanol (70%), methanol (>98.5%), DMSO*, pure haematoxylin, liquid nitrogen, water and mechanical abrasion**
  • Marking is temperature resistant up to 100°C and down to -196°C (liquid nitrogen)
  • Patent pending Thermal Pixel Printing technology


  • Metallic blue, black and white ink ribbons available to print on all kind of tube colours and tubes with dark coloured content
  • Changing the ink ribbon is quick and easy
  • Wide range of adapters available for different diameter tubes

Economic Efficiency / Prints per Ribbon

A 300 m ink ribbon can be used to mark up to 100,000 tubes*** - competitive “per mark” cost

The maximum number of prints per ribbon depends on the horizontal length of the print.
For example, a horizontal print of 3 mm in width (e.g. one line of vertical text) will allow you to print close to 100,000 tubes (300 m ribbon length / 3 mm print).
With a 6 x 6 mm datamatrix (2D) print, you can print close to 50,000 tubes (300 m ribbon length / 6 mm print).
There is minimal waste between the prints.

* Blue ribbon is resistant to 70% DMSO. Black and white ribbons are 100% resistant.
** Marking is non-resistant to Xylene and less resistant to Acetone. 
*** Depending on horizontal dimensions of the print. E.g. when printing a 6 x 6 mm 2D code, one ribbon is sufficient for 50,000 prints.


Tube Compatibility

The TubeMarker™ 2 delivery package contains tube adaptors with hole diameters of 8.5 mm, 11.5 mm and 12.7 mm. These tube adaptors are compatible with the most common centrifuge tubes, such as 1.5 ml/2 ml tubes, 0.5 ml tubes, 2D cluster tubes and cryo tubes. Adaptors for 2 ml screw cap tubes with 10 mm in diameter, 15 ml tubes, 50 ml tubes and Matrix tubes are available separately, see ordering information. To support tubes in the tube adaptor, the tubes require a “lip” as they are not supported from the bottom. Please contact our customer service for any custom adapter you may need.
