Product Overview
Lab142-429-2A cryogenic freezer labels use T429 matte white PET polyester as the face stock and are laboratory labels for -196 °C LN₂ to 121 °C autoclave environments, combining a 40 × 15 mm main label with an 11 mm secondary label to identify cryovials and biobank containers.The main label is a horizontal strip with an aspect ratio of about 2.7:1; its 40 mm length accommodates a complete sample ID plus one barcode. The secondary label zone is a separate segment, output on the same roll as the main label, for cap, rack position or other zone identification.
The application scope stated on this page is laboratory cryovials, biobanks and -80 °C environments, corresponding to ULT freezers and low-temperature cold storage rather than LN₂ dewars: sample access is more frequent and more tubes are counted per check, so labeling needs center on long IDs, fixed positions and no tube-by-tube searching during inventory. The main label carries the ID and barcode, the secondary label carries zone information, both completed in one pass per roll, reducing the step of applying two rolls of labels per tube.
Face stock and temperature resistance follow the T429 row of the official material guide: matte white PET polyester film, officially described as "the ideal choice for labeling frozen surfaces," passing all four tiers — -196 °C LN₂, -80 °C freezer, 100 °C hot water and 121 °C autoclaving — with official applications checked for cryovials/test tubes and packaging labeling. Four-tier coverage means a single label can accompany a sample through the entire pre-processing chain of cryopreservation, rewarming and sterilization/inactivation without re-labeling or replacement.
Key Features
幅
40x15mm long horizontal main label
2.7:1 horizontal layout; the 40 mm length fits a complete sample ID plus one barcode without truncating ID digits due to limited space.
区
Main + secondary dual-zone design
The 11 mm secondary label is output on the same roll as the main label, completing tube body and cap/rack position labeling in one pass and eliminating consumable changes.
温
All four temperature tiers passed
The T429 row of the official guide covers -196 °C LN₂, -80 °C freezer, 100 °C hot water and 121 °C autoclaving.
贴
Flat-adhesion design for frozen surfaces
The matte white PET polyester film surface is flat; text and barcode edges remain clear when applied to the flat section of cryovials and stay readable after handling in -80 °C freezers.

Typical Applications
Sample storage in ULT freezers
The main label on the tube body carries the full ID and barcode; the secondary label marks the rack or box position, so inventory checks read the rack number first, then the tube ID.
Cryovial cap zone labeling
Cap space is narrow and unsuitable for long fields; the 11 mm secondary label is dedicated to cap position marking, with the cap label for position and the tube body label for ID, forming two-level identification.
Batch handover in biobanks
Continuous output per roll with main and secondary labels fed as a group; one batch of samples completes both ID and zone information, so handover checks need no separate list.
Low-temperature transport and packaging labeling
Official applications include packaging labeling; cryobags and transport box exteriors can be labeled under the same ID system, with outer labels matching tube IDs one-to-one.
Labeling & Output Notes
1
Defrost and dry the tube surface
After removing samples from -80 °C, defrost and dry the tube surface so the cryogenic adhesive achieves initial adhesion on a dry, clean surface, avoiding a condensed-water film layer.
2
3mm end overlap
Official rules require at least 3 mm end overlap when T429 is applied to cryovial surfaces. If the 40 mm main label is wrapped around a small-diameter tube, confirm the seam position and overlap allowance first.
3
Plan main and secondary zones
Define field assignments for the main and secondary labels before output; write the ID in only one place to avoid duplicating space across both zones.
4
Finalize the ID template once
Before batch output, lock the ID digit count, barcode symbology and secondary label fields; use the same template across batches of a project for long-term traceability and retrieval.
FAQ
Q: In the 40x15+11mm combination format, which part is the 11mm?
A: The page name specifies a combination format consisting of a 40x15mm main label plus an 11mm secondary label. The specific die-cut shape of the secondary zone (round or square) is subject to the die-cut drawing confirmed in the order and the delivered product; before ordering, you may provide the target tube diameter for our product manager to confirm the layout.
Q: How does this compare with the 25.4x9.53mm narrow strip version?
A: Both are horizontal strips; the difference is structure and information capacity. This version has a 40mm main label plus an 11mm secondary label, so the main label fits a complete long ID and barcode and provides cap/rack zone separation; the 25.4x9.53mm is a single-zone narrow strip using wrap-around overlap, suited to small-diameter tubes that need only one ID segment or a short barcode. Both use T429 face stock with the same temperature tiers.
Q: Can it be used in LN₂ environments?
A: The T429 row of the official guide covers all four tiers — -196 °C LN₂, -80 °C freezer, 100 °C hot water and 121 °C autoclaving — so it is usable in LN₂ scenarios. Official rules require at least 3 mm end overlap when applied to cryovial surfaces; in LN₂ scenarios also allow sufficient overlap and press the seam firmly.
Q: Does the labeling remain legible after sample rewarming or autoclaving?
A: T429 passes all four temperature tiers; when printed with BRL-80-BK or BRL-110-BK cryogenic ribbon, the transferred layer can accompany samples through freezing, rewarming and sterilization. Actual legibility depends on print density, symbology and the sterilization program; small-batch verification is recommended first.
Selection & Usage Guide
Related options in the same family: for a large label area fitting a QR code and multiple field lines on a single label, choose the 35x25mm version; for streamlined fields prioritizing labeling throughput, choose the 25x17mm three-column die-cut version; for narrow strips with wrap-around overlap on small-diameter tubes, choose the 25x10mm or 25.4x9.53mm strip version; for routine freezing above -40 °C only with cost priority, choose T419 gloss white PET or T329 matte white PP; for all-scenario general use and microscope slide archiving, choose T629 nylon cloth; for pathology xylene resistance and H&E staining processes, choose T424 with BRS series ribbon. For more materials and specific applications, please contact our product manager for selection.
- Before ordering, provide the target tube diameter and cap dimensions to confirm that the end overlap after wrapping the main label meets the official 3mm requirement, and confirm the secondary zone shape.
- For long ID layouts, standardize the digit count and barcode quiet zone distance; use the same template across batches of a project to reduce scan-reading variation.
- After printing and labeling, let labels rest per laboratory procedures before entering low-temperature environments; adhesion performance is subject to actual usage conditions.
Note: The temperature tiers, face stock and official application scope on this page are subject to the T429 row of the official material guide and the product specifications section; the die-cut shape of the secondary label in the combination format is subject to order confirmation.
