What size label fits a 3mL peptide vial?

The standard label sizes for 3mL borosilicate crimp vials (16mm diameter) are 1.5 x 0.75 inches (OnlineLabels OL1067, 60 per sheet), 1.75 x 0.5 inches (Avery 5167, 80 per sheet), or 40x20mm and 30x15mm rolls for Niimbot and Phomemo thermal label makers. These dimensions wrap cleanly without overlapping the crimp cap or hiding the liquid meniscus.

How do I print peptide vial labels on a Niimbot or Phomemo thermal printer?

Select your thermal roll size (40x20mm, 30x15mm, or 50x30mm) in the top dropdown on PeptideLabelMaker.com, customize your compound and reconstitution math, and click the 300 DPI PNG button on your label card. Open the downloaded PNG image inside the Niimbot or Phomemo app to print at 1:1 resolution.

How do I calculate U-100 insulin syringe units for reconstituted peptides?

Divide the total lyophilized vial mass (in mg or IU) by the bacteriostatic water volume (in mL) to get your concentration per mL. Multiply your target dose divided by concentration per mL by 100 to get exact U-100 syringe units. PeptideLabelMaker.com calculates and stamps this onto your vial label automatically.

What is the best waterproof sticker paper for refrigerator and freezer vials?

For inkjet and laser printers, weatherproof matte polyester (such as Maestro OL1067) or printable waterproof vinyl full sheets resist condensation at 2-8°C and -20°C freezer storage without smudging.

❓ Frequently Asked Questions (Vial Sizes, Thermal PNGs & Reconstitution Math)

What size label fits a 2mL, 3mL, or 10mL peptide vial?
Standard 3mL & 5mL vials (16mm–22mm diameter) fit 1.5" × 0.75" (OL1067), 1.75" × 0.5" (Avery 5167), or 40×20mm thermal rolls. Micro 2mL vials and 3mL pen cartridges fit 1.5" × 0.5" (OL1100) or 30×15mm thermal rolls. 30mL BAC water bottles and storage cases fit 2.625" × 1.0" (Avery 5160).

How do I prevent inkjet or laser vial labels from smudging in the refrigerator?
Use weatherproof matte vinyl or polyester sheets rather than standard paper address labels, and allow ink to dry for 60 seconds before applying to cold glassware.

How are U-100 syringe units calculated from mg and Bacteriostatic Water mL?
Concentration (`mg/mL`) equals total vial mass (`mg`) divided by diluent volume (`mL`). On a standard U-100 syringe (`100 Units = 1.0 mL`), `10 Units = 0.10 mL`, and your draw units equal `(Target Dose ÷ Concentration per mL) × 100`.

Can I reuse a partially printed 8.5"×11" sticker sheet?
Yes—enter the number of already-peeled stickers in the "Skip First X Empty Stickers" box so printing starts on your first fresh sticker slot.
