Great for 3ml custom peptide vials!
Ordered the Laser Silver labels for our 3ml custom peptide vials in the lab. The stock film is highly resilient—completely survived the -20°C standard freezer storage without any edge curling or fading from chemical smudges. The M2 thermal transfer system is an absolute lifesaver for small-batch clinical test prep.

Perfect for our laboratory workflows
Flawless adhesion on micro-vials. We required specialized medical vial labeling for our biological samples, and this package delivered exactly what we needed. The text is crisp and entirely chemical-proof against standard lab alcohol smudging. Will definitely reorder the replacement rolls from officekoala!
