Print sample barcodes from Excel
Do this in the free app: app.mylabelmaker.com. No signup. Design the label, then print on a Zebra or download PNG / PDF / ZPL.
Sample IDs already live in a sheet. Design one small sticker in the free label maker, barcode {{sample}}, add {{lot}} and {{date}}, then print the tray.
Good to know: This is a design-and-print sticker. It is not a LIMS, chain-of-custody system, or certified lab label.
