Product Overview
Lab111-629-10A is a laboratory cryogenic round label made with T629 nylon cloth face stock, for use from -196 °C LN₂ to 121 °C autoclaving environments. The round die-cut specification is Φ13 mm, 500-1000 labels per roll (page item No. Lab111-648). T629 is the only nylon cloth option in the Lab&HC laboratory medical material guide that covers all four carrier types — ambient temperature, microscope slides, cryovials and conical tubes. It offers good conformability and easy application, and is commonly used as a general-purpose base stock label in biobanks, drug discovery and cell laboratories.
Compared with rectangular labels, the value of Φ13 mm round die-cut lies in point labeling: the top of tube caps, positioning points on the tube body, and round marking positions on one side of slides. No edge trimming or horizontal/vertical layout orientation is needed when labeling — simply peel and apply each label from the continuous roll. In biobank labeling operations requiring batch, same-diameter, position-consistent application, feed and application efficiency is higher than with roll stock that must be cut manually.
Temperature resistance is a hard specification for this series: this T629 nylon cloth model covers four grades — LN₂ -196 °C, freezer -80 °C, hot water 100 °C and autoclaving 121 °C — with no approximate wording. If your workflow does not include ultra-low temperature steps, consider economy models in the -40 °C grade such as T419 / T329.
Key Features
Round
Φ13 mm round die-cut
Ships as individual round pieces — no cutting or edge alignment, just peel and apply. Consistent diameter per roll ensures uniform point height during batch labeling for easy visual verification.
Point
Point labeling on tube cap tops
Round labels suit round points such as cryovial cap tops, and do not obscure the graduations or liquid-level viewing area on the tube body after application.
Cloth
T629 nylon cloth face stock
Cloth-based face stock is flexible and conformable, pressing firmly onto both curved cap surfaces and cylindrical tube bodies. Easy to apply — peel directly from the liner.
Temp
Four-grade performance from -196 °C to 121 °C
Passes all four temperature conditions — LN₂ -196 °C, freezer -80 °C, hot water 100 °C and autoclaving 121 °C. No label change needed across freeze–thaw and sterilization workflows.
Roll
500-1000 labels per roll, continuous feed
Full-roll packaging is compatible with continuous feed on M611 / EOS2/3 / MACH4S models, suitable for batch tube labeling and point re-labeling in biobanks.
Black
Matched with BRL series laboratory cryogenic ribbons
Prints with BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons; face stock and ribbon are the officially recommended combination.

Typical Applications
Point identification on cryovial cap tops
Φ13 mm round labels applied to cap tops form position-read point labels, allowing numbers or color codes to be identified directly from the cap top during biobank retrieval and storage.
Tube body positioning points and narrow-area slide marking
Round labels can be applied directly to round marking positions on the tube body or one side of slides, without occupying the horizontal space required by rectangular labels — ideal for narrow areas and corners.
Batch same-diameter labeling in biobanks
Same-diameter feed per roll ensures consistent label positions. Combined with temperature performance through -196 °C LN₂ and 121 °C autoclaving, labels accompany specimens throughout the workflow.
FAQ
Q: What does the 13 mm round label size refer to?
A: It refers to the diameter of the round die-cut, i.e., each piece is a Φ13 mm round label. The entire roll is the same diameter; peeled labels are finished round pieces requiring no manual cutting.
Q: Can this label be placed directly into LN₂?
A: Yes. The LN₂ temperature resistance of T629 nylon cloth face stock is -196 °C, corresponding to the temperature inside an LN₂ dewar. It also passes freezer -80 °C, hot water 100 °C and autoclaving 121 °C conditions, covering both freeze–thaw and sterilization workflows.
Q: What ribbon and printer are required for printing?
A: Officially matched with BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons, compatible with M611 / EOS2/3 / MACH4S laboratory label printers. The ribbon and face stock combination directly affects print adhesion; this combination is recommended.
Q: Why does the product specification section state "Corner shape: rounded/square optional"?
A: That row is a unified field in the site specification table for the Lab series. This model is a round die-cut piece with no distinction between rounded and square corners; the actual specification is "13 mm diameter." For specific layout and bulk requirements, please contact the product manager.
Selection & Usage Guide
1
Choose shape by labeling point
For cap tops, round marking positions and narrow slide areas, choose Φ13 mm round labels; for horizontal barcodes and multi-line text on the tube body, switch to rectangular models such as 30 × 15 / 35 × 16.
2
Choose size by information volume
Round labels are mainly for numbers, color codes and single-line short information; for QR codes or multiple fields on one label, switch to large-area square labels such as 60 × 40 mm.
3
Choose material by temperature grade
If the workflow includes LN₂ or autoclaving, choose T629; for conventional freezing down to -40 °C only, switch to economy models T419 gloss white PET or T329 matte white PP.
4
Match ribbon and printer model
Use with BRL-80-BK / BRL-110-BK ribbons and M611 / EOS2/3 / MACH4S printers; using them as a set reduces printing and application issues.
- Before labeling, ensure the cap and tube body surfaces are dry, frost-free and oil-free; after applying the round label, press firmly around the edges.
- Store full rolls in a cool, dry place away from direct sunlight and high temperatures to avoid affecting adhesive performance.
- Round label adhesion on curved cap surfaces depends on cap diameter; if cap diameters vary significantly, request a sample for trial confirmation first.
- For custom diameters or pre-printed numbers and color codes, contact the product manager to select according to your biobank coding rules.
Usage Notes
Note: This model uses T629 nylon cloth material with a maximum temperature resistance of 121 °C autoclaving and is not suitable for sterilization processes beyond this range. If the workflow involves higher temperatures or immersion in strong organic solvents (e.g., xylene, H&E staining procedures), please select an alternative; for pathology and histology applications, we recommend chemical-resistant T424 used with BRS series ribbons.
