🖨️ Print Tips
- •Avery 60508 or similar — 1″×2.5″ cryo-resistant labels are standard for research vials
- •In your browser print dialog: set Scale to 100% (no shrink) and disable headers/footers
- •Labels print on white background — will show up on standard white label stock
- •Expiry dates shown in red when within 5 days — useful visual warning
- •Use Duplicate to quickly create multiple vials of the same compound with different lot/aliquot notes
Auto-Expiry Reference— reconstituted stability at 4°C (used for automatic expiry calculation)
Click any compound above to load it into the current label. Stability values are based on published data and manufacturer guidance. Always verify with your lot COA and actual reconstitution conditions.
Vial Labeling Best Practices
Minimum Required Fields
- •Compound name (full name, not abbreviation)
- •Concentration (mg/mL or mcg/mL)
- •Lot number (from supplier COA)
- •Reconstitution date
- •Expiry date
- •Storage temperature
- •Researcher initials
Cryo Label Requirements
- •Use cryo-resistant label stock (-80°C rated)
- •Avery 60508, ULINE S-11189, or equivalent
- •Write on label BEFORE applying to frozen vial
- •Let printer ink dry before cryo use
- •Avoid smudge-prone inkjet on cryo stock
- •Verify label adhesion before first freeze
Documentation Protocol
- •Log every vial in your lab notebook
- •Record COA lot number — match to label
- •Photo-document label before first use
- •Update expiry if freeze-thaw cycle used
- •Label both vial AND storage box/rack
- •Include RUO notation on all labels
