Product Overview
BRD 博锐迪 Lab&HC laboratory and medical label series · Official material guide, T429 entry
Lab127-429/60x30mm matte white PET polyester biobank label uses matte white PET polyester film as face stock and is a cryovial and test tube label for -80 °C ULT freezer environments, resistant to LN₂ -196 °C, 100 °C hot water and 121 °C autoclaving; the product page also states it supports handwriting. The official material guide defines 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.
60x30mm is a 2:1 long banner layout, the largest nominal width in the T429 family: the 60mm horizontal capacity accommodates long barcodes and full specimen numbers side by side, or long numbers and sampling dates on separate lines. The coexistence of printing and handwriting means primary information is batch-printed by thermal transfer while temporary fields can be added by hand, suited to biobank workflows where intake peaks and emergency re-labeling coexist.
Key Features
轨
Print + handwriting dual track
Page states hand-writable: primary information is batch-printed by thermal transfer; variable fields such as batch numbers and temporary notes are added by hand, so emergency re-labeling does not depend on equipment.
幅
60mm long barcode capacity
The 2:1 long banner has the longest horizontal capacity in the T429 family, with ample room for long barcodes, full numbers and dates side by side or on separate lines.
温
All four temperature levels passed
Per the official table: LN₂ -196 °C, freezer -80 °C, hot water 100 °C and autoclaving 121 °C all passed; information does not detach during rewarming and sterilization.
接
Official 3mm overlap rule
Minimum 3 mm overlap at both ends when applied to frozen tube surfaces; the adhesive bonds to itself to form a ring that resists deep low-temperature shrinkage — the unified application standard for the T429 series.

Typical Applications
-80 °C freezer long-number labeling
For cryovials with long biobank accession numbers, the 60mm banner holds the full barcode and number without truncation, enabling single-scan identification on check-in and check-out.
Print-primary, handwriting-supplement mixed workflow
Batch-print primary tube labels during high-volume intake; for sporadic re-labeling such as extra testing or temporary aliquoting, write directly by hand — the hand-writable face stock stated on the page keeps emergency scenarios running.
Deep-freeze–rewarming–sterilization chain
From -80 °C storage to 100 °C rewarming and 121 °C autoclaving disposal, label information remains readable throughout, meeting specimen handling traceability requirements.
FAQ
Q: What pen should be used for handwriting, and will it rub off?
A: The product page states this item supports handwritten additions. For actual writing, use a marker on the label face stock area and, per standard laboratory practice, let the writing dry before exposure to low temperatures; for large-volume handwriting scenarios, we recommend requesting a sample for hands-on testing first.
Q: Can it be applied to microscope slides?
A: In the official material guide, the application scope of T429 covers cryovials, test tubes and packaging labeling, and does not include microscope slides. For slide archiving, switch to T629 nylon cloth labels; for pathology scenarios requiring resistance to xylene and H&E staining processes, switch to T424 with BRS series ribbons.
Q: Can it be used in LN₂ environments?
A: Yes. The category name "-80 °C freezer label" only indicates the primary temperature range; the official table shows T429 also passes testing in LN₂ -196 °C environments — simply apply following the 3mm overlap rule.
Q: How do I choose between this and the 50x30mm version?
A: For longer numbers and greater horizontal barcode capacity, choose this 60x30mm version; for a more compact layout with all information in three lines, compare the 50x30mm version (Lab014-429). Stocking both rolls covers different tube types.
Selection & Usage Guide
- Full-surface coverage for small single-tube layouts: switch to 20x15mm two-column die-cut (Lab168-429-3) or 25x17mm three-column die-cut (Lab169-429).
- Single-line wrap for narrow tubes: switch to 25.4x9.53mm (Lab062-429) or 25x10mm narrow strip (Lab094-429).
- Primary + secondary label dual-zone combination: switch to 40x15+11mm combination (Lab142-429-2A) for tube body and cap labeling in one pass.
- Economical ambient/standard freezer scenarios above -40 °C: switch to T419 gloss white PET or T329 PP adhesive labels.
- Application notes: ensure tube surfaces are dry and clean before labeling; maintain at least 3mm overlap at both ends for deep low-temperature scenarios; store rolls in a cool, dry place away from direct sunlight.
Note: When applying T429 to frozen tube surfaces, a minimum 3mm overlap at both ends is required; the official table does not include microscope slide applications — for slide archiving, use T629 or T424 instead. The handwriting attribute reflects the page statement; before formal volume adoption, we recommend proofing with your actual writing instruments.
