The production of reference samples, which have to be stored long-term stable and have to be marked, requires a suitable tube. Especially for this demand, we produce NMR tubes with pretapered melting positions, which simplifies sealing the tubes. Due to the tapered position the tubes can be ablated more quickly and with minimal heat exposure, which leads to a protection of the reference samples and simplifies the handling of the tubes for users. In addition, the tubes can be marked with 2D DataMatrix Code, which ensures an identification of the sample, even after years, thanks to the unique number. The code can be customized and be read without any problems with an appropriate camera and set-up. Since the marking is worked directly into the glass, the labeling is irreversible.
