IntelliXmark is designed to directly print text, linear barcodes, 2D codes and graphics onto plastic sample tubes, substituting the need for labels or marker pens which can be less reliable. With IntelliXmark there is no longer a need to use 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. Printing straight to the tube surface is much easier and faster than marking by hand.
