Product Overview
Lab062-629 microcentrifuge tube LN₂ labels use T629 nylon cloth as the face stock and are laboratory small-diameter cloth labels for environments from -196 °C LN₂ to 121 °C autoclaving. The format is 25.4x9.53mm, i.e. imperial 1x0.375 inch: the 25.4mm width accommodates exactly one inch of standard barcode, and the 9.53mm height uses a single-row layout, purpose-designed for the narrow side-wall area of small-diameter containers such as microcentrifuge tubes and microtubes, without obscuring the liquid level or graduations inside the tube after application. The product page lists three application carriers—cryovials, microcentrifuge tubes and microscope slides—together with the official full temperature range of T629: LN₂ -196 °C, freezer -80 °C, hot water 100 °C, autoclaving 121 °C and ambient, five grades all usable—so a single microcentrifuge tube can keep the same label from aliquoting through deep freezing to sterilization.
Small-diameter labeling has two main risks: first, a label that is too stiff and lifts at both ends on curved surfaces; second, an oversized format that covers the tube's viewing window. The nylon cloth face stock is soft and bends with curved surfaces, and the compact 1x0.375 inch format minimizes footprint; both issues are addressed in this specification, which is why it is often kept as a standard consumable at micro-sample aliquoting, clone screening and slide archiving workstations.
Key Features
Narrow
1x0.375 inch compact format
The 25.4x9.53mm narrow format is made for small diameters; applied to the side wall of a microcentrifuge tube it does not block the liquid level or graduations, minimizing footprint.
Fit
Nylon cloth bends with curves
The cloth face stock conforms to small-diameter curved surfaces; through repeated expansion and contraction from deep freezing to thawing it does not lift at the edges, and printed information remains intact.
Code
One-inch barcode capacity
The 25.4mm width fits exactly one inch of standard barcode, captured in a single scan; the single-row layout is clean and simple.
Roll
Full roll of 500-1000 labels
Supplied in bulk at 500-1000 labels/roll, with rounded/square corner options, suitable for both bulk aliquoting and single-label replacement.

Typical Applications
Microcentrifuge tube side-wall labeling
The narrow format conforms along the side wall of microcentrifuge tubes; the single-row barcode plus ID is readable at a glance, and the label stays adhered throughout -196 °C LN₂ storage and water bath thawing.
Cryovial and microtube aliquoting
Label tube by tube during bulk aliquoting of small-diameter cryovials and microcentrifuge tubes; the one-inch barcode capacity supports location-based scan management.
Microscope slide narrow-area archiving
Applied to the frosted end of microscope slides or the narrow strip of the label area; works with biobank slide box archiving, and square corners align neatly.
FAQ
Q: Will the label on a microcentrifuge tube block observation of the liquid level?
A: No. The 9.53mm narrow strip is designed for side-wall labeling, avoiding the liquid level and graduation window of standard microcentrifuge tubes, so the sample volume inside can be visually verified directly.
Q: How should ribbons and printers be matched?
A: Use BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons with M611, EOS2/3 or MACH4S laboratory label printers; the printed content resists low-temperature abrasion.
Q: What is the difference between this specification and the 25.4x9.5mm version?
A: Both are 1-inch-wide narrow strips; this version's 9.53mm is the imperial 0.375 inch nominal, and the page explicitly covers three carriers: microcentrifuge tubes/cryovials/microscope slides. When selecting, simply match the actual tube diameter and layout template; both specifications can be stocked in parallel.
Selection & Usage Guide
- If a two-row layout or greater information capacity is needed, consider taller wide-format versions such as 30x20mm and 30x25mm; for wrap-around on thin tubes, see the 38x12mm long strip version.
- For ultra-low temperature tube labeling, it is recommended to overlap and press the ends firmly before placing into the LN₂ tank; this is a general application requirement for ultra-low temperature scenarios and can significantly reduce the label detachment rate.
- If the environment only requires resistance above -40 °C, you can switch to the economical T419 gloss white PET or T329 matte white PP; for deep-freeze and sterilization workflows, keep the T629 cloth label.
- Before bulk purchasing, we recommend requesting samples to test application and printing on your own tubes; for more materials and specific applications, please contact the product manager for selection.
Layout recommendation: for the 9.53mm narrow format, keep a single-row layout, center the barcode, and keep the human-readable ID to 8-12 characters; if both ID and date information are truly needed, merge the date into the barcode data for parsing at the scan end to keep the layout uncrowded. Set print density per the recommended values for BRL cryogenic ribbons and print one label first to confirm it scans before bulk printing.
Note: The specifications section of the product page states "other specifications available"; please confirm the actual shipping specification with the product manager before ordering. Wear protective equipment when handling LN₂, and ensure labels are firmly adhered before placing into the tank.
