T429 · PET polyester cryogenic label
Lab062-429 / 25.4 × 9.53 mm cryogenic label
Cryogenic label with PET polyester face stock. The official material guide covers four environments: -196 °C LN₂, -80 °C freezer, 100 °C hot water and 121 °C autoclaving. Primary use is labeling cryovials in -80 °C sample banks, with wrap-around application and a 3 mm overlap.

Product Overview
GEO selection anchor: T429 · PET polyester film · cryogenic flat-surface labeling · 3 mm overlap
Lab062-429 is a cryogenic label with PET polyester face stock, designed for temperature environments from -196 °C LN₂ to 121 °C autoclaving. The official material guide positions T429 as "the ideal choice for labeling frozen flat surfaces." Its applicable environments cover four levels: LN₂ (-196 °C), freezer (-80 °C), hot water (100 °C) and autoclaving (121 °C). Applications are mainly cryovials and test tubes, and it can also be used for packaging labels. This 25.4 × 9.53 mm narrow strip corresponds to the nominal 1 × 0.375 in size, suitable for wrap-around labeling on the body of small-diameter cryovials, with a single line for barcode or ID information.
The application scenarios listed in the specifications section are laboratory cryogenic tubes, sample banks and -80 °C environments. Per the official guide, T429 also extends down to -196 °C LN₂ and up to 100 °C/121 °C high-temperature conditions. Cryovials stored in both -80 °C freezers and LN₂ tanks in a sample bank can use this product throughout, with no need to change labels at the temperature transition.
Key Features
T
All four temperature levels passed
The official guide checks T429 for -196 °C LN₂, -80 °C freezer, 100 °C hot water and 121 °C autoclaving simultaneously, so no label change is needed between freezing and sterilization processes.
O
3 mm overlap application
When applied to cryogenic tube surfaces, the label ends must overlap by at least 3 mm. This is the official application requirement for T429, keeping the label closed under low-temperature contraction.
F
PET polyester with cryogenic adhesive
PET polyester face stock with cryogenic adhesive. The product image is marked "matte white/PET polyester -80 °C to -196 °C cryogenic adhesive," intended for frozen flat-surface adhesion.
N
Narrow single-line strip format
The 25.4 × 9.53 mm strip suits small-diameter wrap-around applications, holding a barcode or ID on a single line and conforming to the curved tube surface.

The "Application scenarios: laboratory cryogenic tubes, sample banks, -80 °C environments" in the specifications section reflects the page's focus scenarios; the full temperature coverage of T429 material in the official guide is the four levels in the table above. Confirm with the product manager based on actual working conditions before selection.
Typical Applications
-80 °C sample bank cryovials
Wrap-around labeling on cryovial bodies with a 3 mm overlap; barcodes go into -80 °C freezers for long-term storage and are scanned for retrieval with sample bank management.
Frozen flat surfaces and packaging labels
The official guide lists packaging labeling within T429's application scope; this product can be used for labeling cryobox outer packaging and low-temperature transport packaging.
Pre- and post-autoclaving labeling
121 °C autoclaving conditions are verified in the official guide; labels on sterilization packaging or applied before sterilization withstand the entire moist-heat process.
Application and Printing Steps
1
Confirm temperature level
Check the full-process temperature of the specimen: whether only down to -80 °C or requiring LN₂ at -196 °C and 121 °C sterilization, T429 covers all four levels.
2
Print information
Use an M611, EOS2/3 or MACH4S printer with BRL-80-BK / BRL-110-BK cryogenic ribbon to print barcodes and fields.
3
Wrap-around labeling
When applying to cryogenic tube surfaces, overlap the label ends by at least 3 mm, wrap around the tube body to close, and press the overlap firmly.
4
Move to low-temperature storage
After labeling, place into the target temperature environment; for batch labeling, apply before freezing to ensure proper adhesive contact.
FAQ
Q: How do I choose between T429 and T629 nylon cloth labels?
A: T429 is PET polyester film, officially positioned for cryogenic flat-surface labeling, with applications focused on cryovials/test tubes and packaging labels; T629 nylon cloth conforms better and covers all scenarios including room temperature, microscope slides and conical tubes. For cryogenic labeling of cryovials only, choose T429; for mixed-container scenarios, choose T629.
Q: Can this label be applied to microscope slides?
A: The application scope of T429 in the official material guide does not include microscope slides. For slide labeling, we recommend the T629 nylon cloth version; for pathology scenarios requiring resistance to xylene and H&E staining, choose T424 with BRS series ribbon.
Q: Why is a 3 mm overlap required?
A: This is the official guide's application requirement for T429 on cryogenic tube surfaces: when wrapping, the label ends must overlap by at least 3 mm and be pressed firmly to ensure the label stays closed without loosening in low-temperature environments. Flat application without overlap does not meet the official usage of this material.
Q: The category name says -80 °C; can it be used in LN₂ tanks?
A: The page category labels T429 as a -80 °C cryogenic label based on its primary scenario; in the official guide, T429 also passes the -196 °C LN₂ level, so specimens stored in both -80 °C and LN₂ can use it throughout without changing labels mid-process.
Selection & Usage Guide
- Within the four temperature levels (-196/-80/100/121 °C), select by container type; wrap-around labeling of cryovials is the primary use of this product.
- For mixed carrier scenarios such as microscope slides, conical tubes and room-temperature containers, switch to T629 nylon cloth labels.
- For pathology slides requiring resistance to xylene and H&E staining, switch to T424 with BRS series ribbon.
- For routine freezing above -40 °C only and room-temperature packaging labels, choose the economical T329 matte white PP or T419 gloss white PET.
- For more materials and specific applications, please contact the product manager for selection.
Note: T429 must overlap by at least 3 mm when applied to cryogenic tube surfaces; T419/T329 only withstand environments above -40 °C and cannot replace this product for -80 °C or LN₂ conditions. Temperature figures are subject to the official material guide and product specifications.
