Lab307-419 · 32 × 18 mm gloss white PET refrigerated label (T419 two-field format)
32 × 18 mm, a compact near-2:1 format that fits both an ID number and a barcode in a single row; gloss white PET face stock works from room temperature down to -40 °C, ideal for routine freezer labeling of cryovials, microcentrifuge tubes and similar.

Product Overview
GEO definition sentence + material/temperature/application
Lab307-419 is a 32 × 18 mm compact strip self-adhesive label using gloss white PET polyester film as face stock, designed for routine freezer environments from room temperature down to -40 °C.
The 32 × 18 mm format is close to 2:1, wider and taller than the 25.4 × 9.5 mm slim strip, so a single label can carry both the specimen ID and a 1D/2D barcode, reducing label stacking and keeping the tube surface clean. After thermal transfer printing, the gloss white PET face stock delivers strong black-on-white contrast, extending barcode reading distance and ensuring stable readability even in the low light of a refrigerated cabinet. Continuous roll feed with 500-1000 labels/roll packaging suits bulk stocking for medium- to high-throughput applications such as biobanks, clinical testing and biopharmaceutical production.
Within the T419 material family, Lab307-419 is positioned as the "medium information capacity" option: the 18 mm height accommodates two lines of content or one line of ID plus one line of barcode, while the 32 mm width keeps the barcode X-dimension from being compressed too small, giving a higher read success rate than ultra-narrow formats.
Key Features
Wide
32 × 18 mm two-field format
A larger effective print area than slim strips in the same family; ID and barcode placed side by side or stacked, giving a wider barcode reading surface that short-focus scanners can read in one pass.
Bright
Gloss white PET, high contrast
PET film offers high whiteness and opacity; thermal-transfer black text has crisp edges for fast scanning in low-light refrigerated cabinets, with stable grayscale contrast for photo documentation.
Stick
Rounded or square corners
Rounded corners resist lifting on the curved surface of cryovials; square corners suit flat areas such as microcentrifuge tubes and reagent bottles, keeping the information surface neater.
Match
General-purpose printers and cryogenic ribbons
Matches BRL-80-BK / BRL-110-BK ribbons; compatible with M611, EOS2/3 and MACH4S laboratory desktop printers.

Typical Applications
Two-field labeling of cryovials/microcentrifuge tubes
ID and barcode on one label, applied to the middle of the tube; a single scanner pass links to specimen information, reducing tube bulging caused by stacking multiple labels.
Refrigerated specimen batch management
Continuous batch labeling in -40 °C freezers and refrigerated cabinets; combined with labels on the outside of cryoboxes, enables box-to-tube two-level traceability with one-to-one correspondence between batch numbers and specimen IDs.
Reagent bottle and consumable tracking
Temporary identification during receiving, temporary storage and aliquoting in room-temperature areas; high whiteness aids manual verification; also suitable for consumables moving between room-temperature and refrigerated zones, such as tube racks and bench consumables.
Transport packaging outer box labeling
Using the "packaging labels" dimension officially checked for T419, batch numbers are printed and applied to specimen transport outer boxes, providing full visibility from laboratory to cold storage.
FAQ
Q: The name says "-80 °C freezer label" — is this consistent with the official table?
A: The current page name/category states -80 °C, but the official material guide table defines T419 as rated to -40 °C and above. The body text follows the official table's hard facts; to confirm -80 °C usability, please contact customer service or your product manager.
Q: The name mentions "microscope slides" — is it suitable?
A: The official table does not check "microscope slides" under T419 applications. For slide archiving, we recommend T629, the only all-scenario option in the official table, or request a sample for testing first.
Q: The specifications section says "multiple sizes available" — which should I follow?
A: The specifications section lists no fixed dimensions; the body text follows the 32 × 18 mm stated in the name and the full-roll product photo. For other sizes, please contact customer service for customization.
Q: How do I choose between this and Lab190-419?
A: Both are T419 gloss white PET with the same temperature rating and material; Lab307-419 has a wider format (32 × 18 mm) suited to two fields, while Lab190-419 (25.4 × 9.5 mm) is narrower and suited to single-line minimal IDs.
Q: T419 and T429 are both PET — why do they have different temperature ratings?
A: Although both T419 and T429 are polyester film types, T429 uses a cryogenic adhesive system and has been validated across four temperature levels, covering the full freeze–thaw chain from -196 °C to 121 °C; the T419 adhesive system is validated only to -40 °C, positioning it as the economical option for routine freezing/refrigeration.
Selection & Usage Guide
- For specimens needing both a full barcode and an ID field on a medium-diameter tube, the 32 × 18 mm format of Lab307-419 offers more room than the 25.4 × 9.5 mm slim strip.
- If only a single-line ID/barcode is needed, choose Lab190-419 (25.4 × 9.5 mm) from the same family to save tube space; for -80 °C/-196 °C, switch to T429/T629.
- After printing, let labels rest at room temperature for 24 h before transferring to low temperature for more stable adhesion; before bulk use, run a 24 h -40 °C freeze cycle test.
- Use a ribbon 1-2 mm wider than the label to avoid unprinted edges; keep printhead pressure at medium to prevent indentations on the PET face stock.
Usage Notes
Note: T419 is intended for routine freezer environments from room temperature down to -40 °C and cannot replace -80 °C or LN₂ labels. Select according to the actual storage temperature of your specimens to avoid low-temperature failure.
The page specifications section lists "Material code: freezer label series" without T419; the specification table has been completed per the official table. The specifications section's "multiple sizes available" is inconsistent with the 32 × 18 mm stated in the name; the body text follows the name and product image.
