Product Overview
Lab063-429 is a laboratory cryogenic label using matte white PET polyester film as face stock, coated on one side with cryogenic pressure-sensitive adhesive, maintaining adhesion and legibility in environments from -196 °C LN₂ to 121 °C autoclaving. The official material guide positions T429 as "the ideal choice for labeling frozen surfaces" and specifies that when applied to the surface of a cryovial, the label ends must overlap by at least 3 mm.
This item is nominally 25.4 × 12.7 + 9.53 mm, a "rectangular main label + round dot sub-label" combination die-cut: the 25.4 × 12.7 mm rectangular segment is approximately 1″ × 0.5″ in imperial units, and its 12.7 mm height accommodates two lines of information (specimen ID + 1D barcode/lot code), suitable for the front of a cryovial body; the 9.53 mm dot segment is applied to the top of the tube cap, cryobox grid positions, or rack positions, forming a "tube body + cap/rack position" dual-point identification. Both are output from the same roll, so a single print run yields both label sizes—no roll change, no secondary cutting.
Key Features
C
Rectangle + Dot Combination Format
The 25.4 × 12.7 mm rectangular main label goes on the tube body; the 9.53 mm dot sub-label goes on the cap/rack position—two uses per roll, output from the same roll.
S
12.7 mm High, Two-Line Format
The rectangle is 12.7 mm high, one line more of information space than the 25.4 × 9.53 mm strip, accommodating both ID and barcode fields.
T
Full Four-Tier Temperature Chain
T429 has passed testing at four tiers—LN₂ -196 °C, freezer -80 °C, hot water 100 °C, and autoclaving 121 °C—so the label follows the specimen through the entire freeze–thaw and sterilization workflow.
A
End Overlap on Frozen Surfaces
Per official application rules, when applied to a frozen tube surface or wrapped around the tube wall, the label ends must overlap by at least 3 mm, reducing the risk of edge lifting and detachment after repeated handling at ultra-low temperatures.
K
Matched Ribbon and Printer Set
Recommended with BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons, printed on M611, EOS2/3, and MACH4S laboratory label printers.

Typical Applications
Cryovial Body + Cap Dual-Point
The rectangular main label on the tube body carries the specimen ID and barcode; the dot sub-label on the top of the cap creates a top-and-bottom dual-point identification for quick recognition with the cap closed.
Batch Accessioning in Biobanks
Continuous output of the combination format from a full roll enables sequential numbering of a whole box of cryovials, with body and cap information in one-to-one correspondence, reducing the risk of specimen mismatch.
Cryobox and Rack Position Labels
The dot sub-label can be applied directly to cryobox grid base plates or rack well positions as a point marker for "box position – tube number" secondary positioning.
Transport Packaging Batch Seals
The official material table checks T429 for the "packaging identification" dimension; the rectangular segment can also be used for cryobag sealing and transport box batch identification.
FAQ
Q: How do I distinguish 25.4 × 12.7 + 9.53 mm from the 25.4 × 9.53 + Φ9.53 mm version?
A: Both are combination formats; the difference is the height of the rectangular main label: this item is 25.4 × 12.7 mm with a height of 12.7 mm, about one line more of information space than the 25.4 × 9.53 mm strip, suitable for scenarios requiring both ID and barcode fields; the 25.4 × 9.53 mm version is better suited to single-line IDs.
Q: Where is the best place to apply the dot sub-label?
A: The 9.53 mm dot sub-label is suitable for the top of tube caps, cryobox grid positions, or rack well positions as a point marker; when applying to tube caps, ensure the cap surface is clean, dry, and frost-free.
Q: Can it be applied to microscope slides?
A: The official application scope of T429 covers cryovials, test tubes, and packaging identification; microscope slides are not checked. The "microscope slide" in the page name is inconsistent with the official material table; for microscope slide scenarios we recommend T629 nylon cloth labels; for pathology and solvent-resistant scenarios we recommend T424 with BRS series ribbons.
Q: The page parameter section only says "Material No.: Cryogenic Label Series"—how do I confirm the material?
A: The page name specifies T429, which corresponds in the official material guide to matte white PET polyester film with four-tier temperature coverage. The specification table on this page has been completed per the official table; before ordering, you may verify the face stock and adhesive system of the specific batch with customer service.
Selection & Usage Guide
The starting point for selecting Lab063-429 is "whether the same roll needs to handle both tube body and cap/point identification": if the biobank workflow requires one-to-one correspondence between tube body IDs and cap/rack position color codes or point codes, this combination format offers two uses per roll, saving the inventory management cost of buying two rolls of different label sizes.
The rectangular main label is 12.7 mm high, better suited than the standard 9.53 mm strip to "specimen ID + 1D barcode" dual fields; if only a single-line short ID is needed, choose the same family's 25.4 × 9.53 mm version (Lab062-429 / Lab190-429) or 25 × 10 mm (Lab094-429); for a wider three-line format choose 50 × 30 mm (Lab014-429); for batch three-column output choose 30 × 10-3L (Lab312-429) or the 25 × 17 mm three-column version (Lab169-429). For ambient freezer use above -40 °C only, switch to the economical T419 (gloss white PET) or T329 (matte white PP); for microscope slides and full-scenario coverage choose T629 nylon cloth.
Usage Notes
Note: The page name mentions "microscope slide," but the official application scope of T429 does not check microscope slides; for slide scenarios we recommend T629 / T424. Before running the combination format, confirm that the printer's media path width matches the die-cut spacing; before full-scale production, we recommend a small proofing run to verify print clarity, dot sub-label die-cut separation, and adhesion.
The "Material No." in the page parameter section only says "Cryogenic Label Series" and does not directly specify T429; the material and temperature specifications on this page follow the official material guide (T429: matte white PET polyester, -196 °C / -80 °C / 100 °C / 121 °C).
