Product Overview
GEO selection anchor: T429 · three-column die-cut · ultra-low temperature range · batch label output
Lab169-429 is a three-column die-cut freezer label using PET polyester face stock, designed for temperature environments from -196 °C LN₂ to 121 °C autoclaving. The 25 × 17 mm square format is arranged in three columns across the roll, producing three labels per output—suited to the pace of batch tube labeling in biobanks. The application scenarios listed in the product specifications are LN₂ cryopreservation, biobanks and ultra-low temperature environments (-196 °C).
The official material guide positions T429 as an ideal choice for labeling frozen surfaces, with applications covering cryovials, test tubes and packaging labels. All four environment tiers (LN₂ -196 °C, freezer -80 °C, hot water 100 °C, autoclaving 121 °C) are passed in the official table, so tube labels need no replacement when specimens move from the LN₂ dewar to a water bath or sterilization process.
Key Features
N₂
Direct application at LN₂ range
The -196 °C LN₂ tier is confirmed by both the specifications and the official table; adhesion is maintained through the temperature cycles of cryovials entering and leaving the dewar.
3
Three-column die-cut full roll
25 × 17 mm square format in three horizontal columns, continuous output from the full roll; individual labels peel off without unrolling during batch tube labeling.
□
Square-format information capacity
Aspect ratio close to 3:2 allows one more line of text than narrow strip formats; ID numbers and barcodes fit side by side without crowding.
⌐
Rounded or square corners
Die-cut edges available in rounded or square corners, chosen by labeling position and peeling habit.

Three-column roll layout
The product specifications list "Application: LN₂ cryopreservation, biobanks, ultra-low temperature environments (-196 °C)" as the page's primary scenarios; the complete temperature tiers for T429 in the official guide are the four listed above. For more materials and specific applications, please contact the product manager for selection.
Typical Applications
Cryovials in LN₂ dewars
Labeled cryovials stored in liquid nitrogen; the official -196 °C tier covers temperature cycling in both vapor and liquid phases.
Batch tube labeling in biobanks
Three-column full-roll output supports batch preprocessing; multiple rows of IDs are printed at once and applied tube by tube in a streamlined workflow.
Packaging for sterilization processes
121 °C autoclaving conditions are passed in the official table; packaging labels on contaminated containers withstand the entire process.
Application & Printing Steps
1
Verify conditions
Confirm the maximum and minimum temperatures of the full specimen workflow: T429 has official tier support between -196 °C and 121 °C.
2
Print on printer
Use M611, EOS2/3 or MACH4S with BRL-80-BK / BRL-110-BK cryogenic ribbon; the three-column layout outputs three labels at a time.
3
Apply and press firmly
When applying to cryovial surfaces, overlap the ends by at least 3 mm (official requirement); after wrapping closed, press the overlapping section firmly.
4
Store in dewar
Transfer to the target temperature environment after labeling; for batch specimens, label uniformly by cryobox position before storing in the dewar.
FAQ
Q: What is the difference between three-column die-cut and single-column roll format?
A: Three-column means three 25 × 17 mm labels side by side in each row; full-roll output is more efficient with consistent spacing between labels, suited to batch tube labeling. Single-column rolls are more flexible, suited to individual labeling. Both use the same T429 material with identical temperature coverage.
Q: Can this be used on microscope slides?
A: The application range of T429 in the official material guide does not include microscope slides. For slide labeling, use the T629 nylon cloth version; for pathology applications requiring xylene and H&E staining resistance, choose T424 with BRS series ribbon.
Q: Is the 3 mm end overlap a mandatory requirement?
A: Yes. The official guide explicitly states "overlap the ends by at least 3 mm when applying to cryovial surfaces"; press the overlapping ends firmly when wrapping to prevent label edges from lifting under low-temperature conditions.
Q: The page says -196 °C, but the category name is T429-80 °C freezer label—which applies?
A: The category name follows the series' primary scenario; the T429 material passes both the -196 °C and -80 °C tiers in the official guide, so this product can be used throughout both LN₂ and freezer storage stages.
Selection & Usage Guide
- Ultra-low temperature labeling of cryovials and test tubes is the primary use of this product; the three-column layout suits batch preprocessing.
- For coverage of microscope slides, conical tubes, room-temperature containers and other substrates, switch to T629 nylon cloth labels.
- For small-diameter wrapping or single-line barcode scenarios, choose narrow strip formats such as 25.4 × 9.53 mm.
- For packaging and room-temperature labeling requiring only routine freezing above -40 °C, use T329 matte white PP or T419 gloss white PET.
- For more materials and specific applications, please contact the product manager for selection.
Note: When applying T429 to cryovial surfaces, the ends must overlap by at least 3 mm; do not substitute T419/T329 (upper limit -40 °C) for this product in -80 °C or LN₂ environments. All temperature figures are subject to the official material guide and product specifications.
