Product Overview
Lab190-429 is a laboratory cryogenic label using matte white PET polyester film as face stock, with a matte-finished surface and single-side cryogenic adhesive coating, 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 requires a minimum 3 mm overlap at both ends when applied to frozen tube surfaces.
This model is nominally 25.4 × 9.53 mm, i.e., an exact imperial 1″ × 0.375″ conversion, consistent with the dimensional standards of many imported cryogenic consumables and existing laboratory label templates, so no layout adjustment is needed when reusing existing templates and replacing label consumables. The matte white surface reduces glare under strong light and low-temperature frosting conditions, delivering more stable performance in barcode scanner reading and imaging documentation. Continuous full-roll feed is suitable for long serial numbering by box and by batch in biobanks.
Key Features
寸
Imperial Exact-Value Standard Strip
25.4 × 9.53 mm corresponds to an exact 1″ × 0.375″ conversion; the dimensional standard matches imported cryogenic consumables and existing label templates, so the original layout can be retained when switching consumables.
哑
Matte White Face Stock
Matte surface treatment reduces glare interference under strong light and condensation frosting conditions, facilitating barcode reading and imaging documentation, with sharper printed character edges.
序
Long Serial Full-Roll Feed
Continuous numbering across the full roll, enabling sequential specimen numbering by box and by batch; 500-1000 labels/roll covers numbering tasks for multiple cryoboxes.
温
Full Four-Tier Temperature Chain
T429 covers four tiers: LN₂ at -196 °C, freezer at -80 °C, hot water at 100 °C, and autoclaving at 121 °C, so the label accompanies specimens through the entire freeze–thaw and sterilization workflow.
贴
End Overlap on Frozen Surfaces
When wrap-around labeling the tube body, wrap fully around the tube wall with a minimum end overlap of ≥3 mm; following the official application guidelines reduces edge lifting and detachment after ultra-low temperature handling.

Typical Applications
Biobank Serial Numbering
Full-roll serial number feed, enabling continuous numbering of incoming specimens by box and by position, combined with cryobox divider row numbers to form two-level positioning of box position and tube number.
Wrap-Around Labeling of Cryovial Bodies
The 25.4 mm length wraps horizontally around the tube wall with sufficient overlap, while the 9.53 mm height carries a single line of numbering and batch code without obstructing the liquid-level observation area.
Microplate and Box Identification
The matte surface does not reflect light within the field of view of imaging and recording instruments, making it suitable for identification positions requiring photographic documentation, such as microplate racks and cryobox bodies.
Freezer Transfer and Packaging Identification
The official material table checks T429 for the "packaging identification" dimension, used for cryobag sealing and transfer box batch identification, flowing with specimens through the -80 °C chain.
FAQ
Q: The page name states "-80~-40 °C"; what temperatures does T429 actually cover?
A: In the official material guide, T429 covers four tiers: LN₂ at -196 °C, freezer at -80 °C, hot water at 100 °C, and autoclaving at 121 °C; the -40 °C tier belongs to T419 (gloss white PET) and T329 (matte white PP), two economy materials with different temperature coverage and must not be conflated. This model follows the official T429 specification.
Q: What is the difference between matte white and gloss white PET?
A: Both belong to the PET polyester face stock family; the differences lie in surface treatment and temperature coverage: matte treatment reduces glare, suitable for biobank scenarios requiring barcode scanning and imaging documentation; gloss white PET corresponds to T419, resistant to environments above -40 °C, and is not suitable for -80 °C freezer and -196 °C LN₂ chains.
Q: Can it be applied to microscope slides?
A: The page name mentions "microscope slide", but the official application scope of T429 covers cryovials, test tubes and packaging identification, and does not check microscope slides. For microscope slides and conical tubes requiring all-scenario identification, we recommend T629 nylon cloth label; for pathology solvent-resistant scenarios, we recommend T424 with BRS series ribbon.
Q: How does it differ from Lab062-429, which is also 25.4 × 9.53 mm?
A: Both share the same dimensions and temperature chain; the differences lie in face stock surface treatment and primary application scenarios: this model is matte white, targeting biobank long serial numbering and imaging documentation scenarios; please confirm the surface treatment and stock of specific batches with customer service when ordering.
Selection & Usage Guide
The starting point for selecting Lab190-429 is "whether the layout needs to follow existing templates": if the existing layout is designed in imperial 1″ × 0.375″, or if you need to replace imported consumables of the same specification, this model is a direct match. If the biobank emphasizes continuous serial numbering and photographic documentation, the low-glare matte white surface treatment is more suitable; if only a standard cryogenic strip is needed, the same-size Lab062-429 can be selected based on stock.
For dual-field (number + barcode) requirements, choose 25 × 10 mm (Lab094-429) or 30 × 20 mm (Lab032-429); for three-line full information, choose 50 × 30 mm (Lab014-429); for single-pass labeling of both tube body and cap, choose combination format Lab038-429; for micro dot labels, choose the 9.53 mm dot version (Lab270-429-5D); for ultra-narrow dual-column, choose 25 × 5 mm (Lab336-429). For environments above -40 °C only, choose T419 / T329 economy models; for xylene resistance and H&E staining processes, choose T424 with BRS series ribbon; for microscope slides and all-scenario coverage, choose T629 nylon cloth. When wrap-around labeling frozen tube bodies, always follow the official application guideline of ≥3 mm end overlap.
Usage Notes
Note: The "-80~-40 °C" stated in the page name is inconsistent with the four-tier coverage of T429 in the official material table (-196 °C / -80 °C / 100 °C / 121 °C); the -40 °C tier belongs to T419 / T329 economy materials. When selecting, please use the temperature chain as the primary criterion, and run a small-batch sample proof to verify adhesion and print quality before formal bulk orders.
The "Material No." in the page specification section only states "cryogenic label series" and does not directly indicate T429; the material and temperature specifications on this page follow the official material guide (T429: matte white PET polyester).
