Lab label tools
The mechanisms behind the editor, explained: codes, runs, sizes and getting the print to come out at the size you designed.
The parts of the editor worth explaining on their own: scannable codes, batch runs, label sizes and print calibration. Calibration is the one most people need first — a label that measures right on screen but prints a few percent small has met a fit-to-page default somewhere, and one test print gives you the exact factor.
- QR code lab label generator38.1 × 19.05 mmEvery QR code here is computed on your device and drawn as vector modules. No image service, no upload, no request carrying your sample identifiers.
- Barcode lab labels38.1 × 19.05 mmA linear barcode needs length. A tube does not have length. That single fact decides most laboratory barcode questions before anything else does.
- Batch lab label maker25.4 × 12.7 mmMost batch label tools give you a copy count. Real runs are two blanks, three of one thing and three of another — so this one takes a list.
- Label size calculatorLabel size on a tube is set by circumference, not by the tube's length. Two numbers give you the answer.
- Print calibrationIf a label measures right on screen and wrong on the bench, the printer is scaling it. A ruler and one test page tell you by how much.
