Frequently Asked Questions
-
What label size is best for peptide vials?
The best label depends on the size of your vial, your thermal printer, and the conditions the labeled vial will encounter. Many popular peptide vials use label sizes around 1.75" x 1".
-
What is the difference between direct thermal and thermal transfer peptide labels?
Direct thermal printers use heat to create an image directly on the label and do not require a ribbon. Thermal transfer printers use a ribbon to transfer the printed image to the label. Direct thermal labels are popular for peptide labels for their low price point. Thermal transfer printing is generally a better option when longer-lasting print is important.
-
Do thermal transfer peptide labels require a ribbon?
Yes. Thermal transfer printers use a ribbon to transfer the printed image onto the label. Be sure to select a ribbon that is compatible with both your printer and label material.

Are peptide labels available for both desktop and industrial thermal printers?
