Design printable cryogenic labels with QR codes
This browser-based lab label maker lays out sample IDs on common cryogenic label-sheet formats with exact row and column positioning. Edit one label, select a range, paste a batch of sample names, create repeated copies, enumerate labels, or apply find-and-replace operations before printing.
QR mode converts the exact text of each non-empty label into a code with high error correction and a white quiet-zone border. Short, unique identifiers usually produce larger modules and are easier to scan on small tubes. A full URL can be encoded when a phone should open a LIMS, ELN, or sample record directly.
Tips for cryogenic tube labels
- Choose the template code that matches the physical label sheet and run a plain-paper alignment test before using cryogenic stock.
- Keep the most important identifier readable as text even when a QR code is included.
- Use a printer, ribbon or toner, and label material rated for the intended temperature, moisture, solvent, and storage duration.
- Scan a sample after printing and again after applying it to the actual tube geometry.
After labeling tubes, their row-and-column locations can be recorded in the freezer box inventory and sample tracker.
Lab label maker FAQ
Can the label maker print QR codes?
Yes. Enable QR codes to encode each label's text. Short sample IDs are recommended for small labels because they create less-dense codes.
Can I import a list of sample names?
Yes. Import CSV data or use Bulk Fill with one label per line. You can also choose how many consecutive copies of each label to create.
Can I send a label sheet to someone else?
Yes. "Share Link" copies a URL that contains the entire sheet—template, font, QR setting, and every label—encoded after the #. Opening it recreates the sheet in the recipient's browser. Because fragments are never transmitted to a web server, the label text is never uploaded anywhere; it only travels wherever the link itself is sent. The copy is independent, so later edits on either side are not shared.
Will the labels survive liquid nitrogen storage?
Survival depends on the physical label stock, adhesive, print method, tube surface, and application procedure—not the layout software. Use cryogenic-rated materials and validate them under the conditions used by your lab.
