Hot resin and chemical resistant labels for embedding in the resin capsule or mold, alongside the sample. The small size of the ResiTAG® label can accommodate various sizes of embedding capsules commonly used in electron microscopy facilities. When printed with our recommended chemical-resistant resin ribbon (XAR-class, GA International), the ResiTAG® label and printout withstand histological resins and oven incubation up to 150°C. In addition to the resin itself, the printout can also withstand ethanol and other alcohols, xylene, toluene, acetone, formalin as well as other harsh chemicals, solvents and histological stains.


  • Chemical-resistant labels withstand embedding in histological resins used in microscopy and can withstand incubation in temperatures up to +150°C
  • Small size accommodates various sizes of embedding capsules & molds
  • Withstand alcohol, xylene, toluene, formalin as well as histological stains exposure
  • Available on 1” or 3” cores for printing with all major brands of thermal-transfer printers

Frequently Asked Questions

Yes, ResiTAG® labels are thermal-transfer printable and require a ribbon to be printed. To achieve the proper printout, these labels require a xylene and solvent-resistant XAR-class ribbon of the same width or larger.

Yes, the labels are intended to be placed directly inside the resin capsule or mold, along with the sample, prior to curing, providing a safe, secure, and long-lasting identification solution.

Yes, these labels are designed for identifying samples embedded in resin capsules, intended for use in electron microscopy. For more information consult our experience support team.

Yes, the resin does not interfere with the scanning of the barcode once it has been hardened.

Yes, ResiTAG labels do not acquire colors from histological stains such as hematoxylin or eosin Y, and can be used to identify microscope slides. For more Histology labeling solutions see here.

Yes, these labels come with a permanent adhesive. However, they can be folded unto themselves, creating an adhesive-free tag.

Barcoding or label design software can be used to create templates that conform to the size of your label. You can then insert design elements within the template, for easy printing.

Yes, we can provide our chemical-resistant ResiTAG labels preprinted with full-color graphics and logos, as well as variable or serialized information from a database. Learn more about our custom printing options.
