Peptide Vial Label Maker

Design a vial label sized for NIIMBOT and Phomemo thermal printers, then print it straight to a NIIMBOT over Bluetooth or download it as a print-ready PNG. Open it from any PepRecon calculator and the label fills itself in, including a QR code that reopens the exact calculation or links to your COA.

QR code

"This calculation" encodes the share link handed over by the calculator, so scanning the vial reopens the exact math. "Custom URL" is handy for linking the batch COA. Tip: run the COA through our COA Reader first and paste its share link here, so scanning the vial opens the parsed, checked report with the lab's verification, not a raw PDF.

How to print it

NIIMBOT + Chrome or Edge: use the Print via Bluetooth button above. The label goes straight to the printer, no app needed. Works on desktop and Android; pair nothing in advance, just pick the printer from the popup.

Everything else (Phomemo printers, iPhone, Firefox/Safari):

  1. Download the PNG (on a phone it lands in your photos or downloads).
  2. Open the NIIMBOT app or the Phomemo app (Print Master / Labelife).
  3. Choose the app's image / photo print option, pick the PNG, and print. The image is already sized for your label at 203 dpi, so print at 100% with no scaling.

Label your vials like you mean it

A reconstituted vial with no label is a coin flip two weeks later. This tool turns the math you just did in a PepRecon calculator into a clean thermal label: compound, vial strength, BAC water volume, concentration, the exact syringe draw, and the reconstitution date, sized for the label stock that NIIMBOT (D11, D110, D101, B1, B21, M2) and Phomemo (D30, D35, Q30, M110, M120) printers actually take.

The QR code is the part your future self thanks you for. Point it at the shared calculation and scanning the vial with any phone camera reopens the exact reconstitution math, or point it at the certificate of analysis for the batch so the paperwork is one scan away. Labels export as pure black-and-white 203 dpi PNGs, which is exactly what a thermal printhead lays down, so what you preview is what prints.
