Product Overview
BRD Lab&HC Laboratory Medical Label Series · T429 entry in the official material guide
Lab014-429/50 × 30 mm biobank medical labels use a matte white PET polyester film face stock and are designed for cryovials and specimen packaging labels used from -80 °C ULT freezers down to LN₂ -196 °C, withstanding the rewarming chain of 100 °C hot water and 121 °C autoclaving. The official material guide positions T429 as "the ideal choice for labeling frozen surfaces" and specifies a clear application rule: when applied to frozen tube surfaces, overlap the ends by at least 3 mm to ensure the adhesive does not lift or crack under deep cryogenic conditions.
The 50 × 30 mm format is a medium-to-large size within the T429 family; a single label can fully accommodate three lines of information—barcode, specimen number and collection date—and is suited to large flat application on cryovial bodies. The official guide also checks the "packaging identification" application dimension, so cryoboxes, cryobags and specimen transport outer cartons can use the same label in roll format for low-temperature identification, reducing consumable variety.
Key Features
T
All Four Temperature Tiers Passed
Official guide test criteria: LN₂ -196 °C, freezer -80 °C, hot water 100 °C and autoclaving 121 °C all passed, covering the complete specimen lifecycle from deep-freeze storage to rewarming and inactivation.
O
Overlap Application on Frozen Surfaces
Official T429 usage rule: when applied to frozen tube surfaces, overlap the ends by at least 3 mm so the adhesive bonds to itself to form a closed loop, resisting cryogenic shrinkage stress.
P
Clear Thermal-Transfer Printing
The matte white PET print surface, combined with BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons, delivers high contrast for barcodes and text, and is directly compatible with M611, EOS2/3 and MACH4S laboratory label printers.
C
50 × 30 mm Three-Line Format
The medium-to-large format fits a complete information system of a barcode plus two lines of text on a single label, eliminating secondary labeling; large flat application on cryovials does not obscure the viewing area.

Typical Applications
Batch Labeling of Cryovials in -80 °C Freezers
When cell lines, plasma and tissue specimens are aliquoted and stored, entire racks of cryovials are batch-printed with three-line information (barcode + number + date) and applied flat tube by tube, establishing a unique identity upon storage.
Biobank Packaging Identification
The "packaging identification" dimension checked in the official guide: cryobox position labels, cryobag body identification and low-temperature labels for specimen transport outer cartons, managed with the same label type and roll as tube labels.
Full-Chain Tracking from Deep Freeze to Rewarming
From removal from the -80 °C freezer, rewarming in 100 °C hot water to 121 °C autoclaving, label information remains intact and legible, supporting full-process traceability without gaps.
FAQ
Q: Can Lab014-429 be applied to microscope slides?
A: In the official material guide, the application range of T429 covers cryovials, test tubes and packaging identification, and does not include microscope slides. For microscope slide labels, we recommend T629 nylon cloth labels or T424 labels resistant to xylene and the H&E staining process; please contact the product manager to confirm selection.
Q: The page category says -80 °C freezer label—what is the actual temperature range?
A: The category name only represents the primary temperature segment. According to the official material guide, T429 passes all four tiers: LN₂ -196 °C, freezer -80 °C, hot water 100 °C and autoclaving 121 °C. This page describes all specifications per the official guide.
Q: Why is overlap required when applying to cryovials?
A: At deep cryogenic temperatures, the tube body and adhesive layer shrink at different rates, and flat butt-applied labels tend to lift during freeze–thaw cycles. The official rule is to overlap the ends by at least 3 mm so the adhesive bonds to itself into a loop, shrinking in sync with the tube body without loosening.
Q: Which ribbon and printer should be used?
A: The page specifications pair with BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons and are compatible with M611, EOS2/3 and MACH4S laboratory label printers for thermal-transfer print-and-apply output.
Selection & Usage Guide
- For batch tube labeling with concise single-label information: switch to the 25 × 17 mm three-column die-cut version (Lab169-429) for higher efficiency with multi-column continuous roll output.
- For small-diameter wrap-around or narrow single-line barcodes: switch to the 25.4 × 9.53 mm slim strip (Lab062-429) or the 25 × 10 mm narrow horizontal strip (Lab094-429).
- For dual-zone combination formats with a tube body label plus an additional label: switch to the 40 × 15 + 11 mm combination version (Lab142-429-2A), with the main label on the tube body and the additional label on the cap.
- For economical room-temperature/standard freezer scenarios above -40 °C: switch to T419 gloss white PET or T329 PP self-adhesive versions for better cost efficiency.
- For pathology slides requiring resistance to xylene and H&E staining: switch to T424 labels, used with BRS series ribbons.
- Labeling application: keep the frozen tube surface dry and clean; if frost forms on tubes taken from low-temperature environments, wipe off the frost before labeling and maintain at least 3 mm overlap.
Note: When applying T429 to frozen tube surfaces, the ends must overlap by at least 3 mm; the official guide does not include microscope slide applications—for slide archiving, use T629 or T424 instead. Temperature values are per the official material guide; do not use directly in chemical environments beyond those specified (e.g., xylene).
