Product Overview
Lab245-429 is a laboratory cryogenic label made with a matte white PET polyester film face stock and a single-side cryogenic adhesive coating, maintaining adhesion and legibility from -196 °C LN₂ to 121 °C autoclaving. The official material guide positions T429 as "the ideal choice for labeling frozen surfaces" and specifies a minimum 3 mm overlap at both ends when applied to frozen tube surfaces.
This model is nominally 24 × 6 mm with a 4:1 length-to-width ratio, the longest option in the T429 family at a 6 mm narrow-band height: the height closely matches the available labeling area on microtubes and small-diameter cryovials, while the 24 mm length leaves a wider character capacity for a single line of text, suitable for carrying sample IDs of 10 or more digits or combined "batch + serial" codes—one label per tube, the full line readable at a glance. Continuous die-cut roll feed eliminates manual cutting; 500-1000 labels per roll covers continuous numbering across multiple cryoboxes.
Key Features
L
24 × 6 mm Single-Column Strip
A 6 mm narrow-band height paired with a 24 mm medium-long segment accommodates longer ID numbers and batch codes on a single line without truncation, with noticeably greater character capacity than the 13 × 6 mm ultra-small rectangle.
T
Full Four-Tier Temperature Chain
T429 has passed testing at four tiers—LN₂ -196 °C, freezer -80 °C, water bath 100 °C and autoclave 121 °C—so the label follows the specimen through the entire freeze–thaw and sterilization workflow.
A
End-to-End Overlap on Frozen Surfaces
Per official application guidelines, a minimum 3 mm overlap at both ends is required when applying to frozen tube surfaces or wrapping around tube walls, reducing the risk of edge lifting and detachment after repeated handling at ultra-low temperatures.
R
Continuous Roll Feed
Die-cut on the full roll, peel and apply—no manual cutting; ideal for sequential labeling of full cryoboxes at accessioning.
S
Matched Ribbon and Printer Set
Recommended with BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons and M611, EOS2/3, MACH4S laboratory label printers.

Typical Applications
Wrap-around labeling on cryovial walls
The 24 mm length wraps around the tube wall with sufficient overlap, carrying sample ID and batch code on a single line for easy tube-by-tube verification when cryoboxes are lined up in rows.
Narrow-band labeling on microtubes and small-diameter tubes
The 6 mm height matches the available labeling area on 0.5-2 mL microtubes and small-diameter cryovials without obscuring graduations or the liquid-level viewing area.
Continuous numbering in biobanks
Sequential roll feed enables continuous numbering of full boxes at accessioning, combined with cryobox divider row numbers for two-level positioning by box position and tube number.
Cryobox and transport packaging labeling
The official material table checks T429 for the "packaging labeling" dimension, suitable for cryobox divider row numbering, cryobag sealing and transport box batch seals.
FAQ
Q: Is 24 × 6 mm suitable for printing 1D barcodes?
A: A 6 mm height is rather narrow for 1D barcodes; single-line short IDs, batch codes or dot-matrix characters are recommended. For full barcodes with reliable scanning, choose wider formats such as 25.4 × 9.53 mm or 25 × 10 mm.
Q: Can it be applied to microscope slides?
A: The official application scope of T429 covers cryovials, test tubes and packaging labeling; microscope slides are not checked. The "microscope slide" reference in the page title is inconsistent with the official material table. For microscope slides, T629 nylon cloth labels are recommended; for pathology and solvent-resistant applications, choose T424 with BRS series ribbons.
Q: How does this compare with the 13 × 6 mm and 25 × 5 mm options?
A: 13 × 6 mm (Lab313-429) is the smallest format, suited to the shortest codes and plate well position dots; 25 × 5 mm (Lab336-429) is a two-column side-by-side die-cut, producing two columns per pass, suited to paired tube-body and cap numbering; this 24 × 6 mm model is a single-column strip with the largest per-label character capacity.
Q: The page specification section only states "Material code: cryogenic label series"—how can the material be confirmed?
A: The page title specifies T429, which corresponds to matte white PET polyester film and four-tier temperature coverage in the official material guide. The specification table on this page has been completed per the official table; before ordering, confirm the face stock and adhesive system of the specific batch with customer service.
Selection & Usage Guide
The starting point for selecting Lab245-429 is "how long is the single-line information": for 4-6 digit short codes, choose 13 × 6 mm (Lab313-429); for paired numbering, choose the 25 × 5 mm two-column model (Lab336-429); for single-line IDs over 10 digits or combined "batch + serial" codes, the 24 mm length of this 24 × 6 mm model offers more room. For full barcodes, step up to 25.4 × 9.53 mm (Lab062-429 / Lab190-429) or 25 × 10 mm (Lab094-429); for one-pass labeling of both tube body and cap, choose the combination format Lab038-429; for batch tube labeling, choose the three-column die-cut Lab169-429; for multi-line full information, choose Lab014-429, Lab127-429 or Lab102-429.
Environmental requirements beyond the temperature chain also determine material choice: for ambient freezing above -40 °C only, switch to the economical T419 (gloss white PET) or T329 (matte white PP); for xylene resistance and H&E staining workflows, choose T424 with BRS series ribbons; for full coverage including microscope slides and conical tubes, choose T629 nylon cloth labels. Before running, it is recommended to feed the full roll once to confirm that the narrow-strip die-cut edges do not lift or jam during feeding.
Usage Notes
Note: The page title mentions "microscope slides", but the official application scope of T429 does not include microscope slides; for slide applications, T629 / T424 are recommended. The 24 × 6 mm format is relatively narrow; single-line short IDs are recommended. For reliable scanning, choose a wider format. Before full-scale production, run a small sample proof to confirm print clarity and adhesion.
The "Material code" field in the page specification section only states "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).
