Product Overview
Lab162-629 cryovial labels use T629 nylon cloth as the face stock and are cloth-based cryogenic labels for identifying biobank cryovials in environments from -196 °C LN₂ to 121 °C autoclaving.The nominal page specification is 40 × 20 mm, with a landscape-to-portrait ratio of about 2:1 — the longest in the rectangular family: the 40 mm clear width is enough to lay out a long specimen ID barcode horizontally, or to place a 2D code and ID side by side, leaving a complete quiet zone for barcode scanner reading.
Face stock properties follow the T629 row of the official material guide: nylon cloth labels are easy to apply, withstand high and low temperatures, and conform well. All five grades are tolerated: -196 °C LN₂, -80 °C freezer, 100 °C hot water, 121 °C autoclaving, and ambient. The cloth substrate deforms in sync with the cryovial diameter as it expands and contracts during freeze–thaw cycles, unlike rigid films whose edges lift after rewarming — making it the right choice for cryovials that repeatedly travel between LN₂ tanks and water baths.
Specification note: the product name states 40 × 20 mm, while the specifications section notes "multiple specifications available, see product detail images." This page organizes selection information based on the nominal 40 × 20 mm; if the actual container size does not match your existing template system, contact the product manager to customize other specifications.
Each roll provides 500–1000 labels in continuous feed and is compatible with BRL-80-BK / BRL-110-BK cryogenic ribbons and M611, EOS2/3, MACH4S laboratory label printers — a single roll covers batch tube-labeling during biobank intake season.
Key Features
Long
2:1 long landscape capacity
The 40 mm horizontal clear width leaves a quiet zone for long ID barcodes or side-by-side 2D codes, enabling single-scan reads and reducing rescans.
Fit
Nylon cloth conforms to curves
The cloth face stock conforms to the curved cryovial surface without lifting, flexing with the tube during freeze–thaw cycles and resisting adhesive failure.
Resist
Five-grade environmental resistance
Official guide T629 row: passes -196 °C LN₂, -80 °C freezer, 100 °C hot water, 121 °C autoclaving, and ambient.
Bulk
Economical full-roll output
500–1000 labels/roll in continuous die-cut format; no frequent roll changes during batch printing, lowering roll stock costs in intake season.

Typical Applications
Long barcode cryovial labeling
For systems with many specimen ID fields (ID + batch + sub-position), the 40 mm landscape width fits the entire barcode on one line without wrapping.
2D code + ID side by side
Mixed layout with the 2D code on the left and human-readable ID and date on the right, enabling dual-channel verification by scan and visual check.
LN₂ tank zone management
Label by rack/cryobox zone; identification remains attached during long-term storage at -196 °C, with scan-based location during retrieval.
Recovery and autoclaving workflows
The cloth identification remains intact and legible through downstream steps such as water bath rewarming and 121 °C autoclaving — no relabeling between steps.
FAQ
Q: The name says 40 × 20 mm, but the specifications section says "multiple specifications available" — which applies?
A: The 40 × 20 mm in the page name is the nominal size for this item, and this page's selection information is organized accordingly. If the cryovial diameter, slide label area, or existing template does not match this size, contact the product manager to confirm other available specifications and custom sizes.
Q: How do the 40 × 20 mm and 38 × 20 mm versions differ?
A: Both use T629 nylon cloth with the same temperature grades. The 40 × 20 mm offers 2 mm more horizontal width, advantageous for side-by-side long barcodes and 2D codes; the 38 × 20 mm focuses on dual cryovial/slide use and two-line layouts. Choose based on printed content width.
Q: Are there pretreatment requirements before applying to cryovials and placing in LN₂?
A: Keep the labeling surface dry and clean, press out air bubbles, and the vial can go into LN₂. Before batch operations, we recommend test-applying one label through a complete freeze–thaw cycle to confirm adhesion and legibility before scaling up.
Q: Which ribbon and printer should be used?
A: Use BRL-80-BK or BRL-110-BK laboratory cryogenic ribbon; compatible printers are M611, EOS2/3, MACH4S laboratory label printers. For other thermal-transfer models, test-print first to confirm.
Selection & Usage Guide
Family selection reference: for two-line text layouts or dual slide use, choose the 38 × 20 mm; for narrow tube wrap-around overlap, choose the 35 × 16 mm / 30 × 15 mm narrow-width versions; for combined rectangular + circular formats, choose Lab038-625 / Lab179-672; for cap-top labeling, choose the Phi13mm circular label; for applications above -40 °C only, choose the T419 / T329 economical versions. For more materials and specific applications, contact the product manager for selection.
- Before printing a full roll, confirm the ribbon width covers the 40 mm format to avoid edge print gaps.
- Apply labels away from graduation lines and liquid-level viewing windows; a consistent mid-tube position facilitates scanning.
- For batch intake, pre-arrange the ID sequence by cryobox level so printing and labeling order match, reducing secondary sorting.
Note: The temperature grades and face stock information on this page are subject to the T629 row of the official material guide and the product specifications section; page images contain promotional banner elements, and actual delivered specifications are subject to order confirmation. Wear cryogenic gloves when handling LN₂ and follow laboratory biosafety procedures.
