Product Overview
Lab312-429 is a laboratory cryogenic label using matte white PET polyester film as face stock, coated on one side with cryogenic pressure-sensitive adhesive, maintaining adhesion and legibility from -196 °C LN₂ to 121 °C autoclaving. The official material guide positions 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.
This item is designated 30×10-3L, i.e., 30 × 10 mm small rectangular three-column die-cut: three labels side by side across the roll width, dispensing three labels simultaneously in a single pass, suitable for bulk labeling of full rows of cryovials. The 10 mm height matches the available labeling area on 0.5–2 mL cryovial walls without obscuring graduations or the liquid-level viewing area; the 30 mm length provides moderate capacity for single-line short IDs, batch codes, or short barcodes. Continuous roll feed greatly improves numbering efficiency during biobank accessioning.
Key Features
3
Three-column die-cut, three per pass
30 × 10 mm small rectangles die-cut in three parallel columns, three labels per pass, ideal for bulk labeling of full rows of cryovials.
N
10 mm height, no view obstruction
The 10 mm narrow-band height matches the available wall area of narrow-diameter cryovials and microtubes without obscuring graduations or the liquid-level viewing area.
T
Full four-tier temperature chain
T429 has passed testing at -196 °C LN₂, -80 °C freezer, 100 °C water bath, and 121 °C autoclaving, staying with specimens through the entire freeze–thaw and sterilization workflow.
A
End overlap on frozen surfaces
Per official application guidelines, apply with at least 3 mm overlap at both ends on frozen tube surfaces to reduce the risk of edge lifting and detachment after repeated ultra-low temperature handling.
K
Matched ribbon and printer set
Recommended with BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons and M611, EOS2/3, MACH4S laboratory label printers.

Typical Applications
Bulk biobank accessioning
Three-column die-cut, three labels per pass, for continuous labeling of full rows of cryovials; ideal for large-scale accession numbering in biobanks.
Single-line ID on cryovial body
30 × 10 mm small rectangle applied to the front of the tube body, carrying a single-line short ID or short barcode without obscuring tube graduations.
Rack labeling around 96-well plates
Three small rectangles can be grouped onto racks or around 96-well plates to form row/column position markers.
Freezer-stage transfer packaging labels
The official material table checks T429 for the "packaging labeling" dimension; suitable for cryobag seals and transfer box batch identification.
FAQ
Q: What does "3L" in 30×10-3L mean?
A: "3L" means the roll is die-cut into three columns (3 lanes), dispensing three 30 × 10 mm small rectangular labels simultaneously in a single pass, suitable for bulk tube labeling; the exact number of columns and die-cut layout are subject to the actual roll.
Q: Is the three-column die-cut suitable for barcode printing?
A: The 30 × 10 mm format is relatively short, so 1D barcode character length must be controlled; short IDs, short barcodes, or 2D codes are recommended. For wider barcode capacity, choose 25.4 × 9.53 mm, 25 × 10 mm, or 30 × 20 mm (Lab032-429) formats.
Q: Can it be applied to microscope slides?
A: The official application scope for T429 covers cryovials, test tubes, and packaging labeling; microscope slides are not checked. The "microscope slide" reference in the page name is inconsistent with the official material table; for slide applications, T629 nylon cloth label is recommended.
Q: The page specification section only states "Material code: cryogenic label series" — how do I confirm the material?
A: The page name specifies T429, and the official material guide corresponds to matte white PET polyester film with four-tier temperature coverage. The specification table on this page has been completed per the official table; before ordering, please verify the face stock and adhesive system of the specific batch with customer service.
Selection & Usage Guide
The starting point for selecting Lab312-429 is "bulk operation efficiency": when rapid continuous numbering of full rows of cryovials is required, the three-column die-cut delivers three labels per pass, reducing the number of passes compared with single-column versions.
If barcode characters are longer, widen horizontally to 25.4 × 9.53 mm (Lab062-429 / Lab190-429) or 25 × 10 mm (Lab094-429); if dual fields (ID + barcode) are needed, choose 30 × 20 mm (Lab032-429) or 35 × 25 mm (Lab112-429-3); for paired numbering, choose the 25 × 5 mm two-column version (Lab336-429) or the 25.4 × 12.7 + 9.53 mm combination format (Lab063-429). For room-temperature freezing above -40 °C only, switch to the economical T419 (gloss white PET) or T329 (matte white PP); for microscope slides and full-scenario coverage, choose T629 nylon cloth.
Usage Notes
Note: The page name includes "microscope slide," but the official application scope for T429 does not check microscope slides; for slide applications, switch to T629 / T424. The 30 × 10 mm format is relatively short, so short IDs/short barcodes are recommended; before formal bulk runs, please proof a small batch to verify print clarity and bulk separation performance.
The "Material code" in the page specification section only states "cryogenic label series" and does not directly specify T429; the material and temperature specifications on this page follow the official material guide (T429: matte white PET polyester, -196 °C / -80 °C / 100 °C / 121 °C).
