Lab121-459 · 66.68 × 15.24 mm ultra-thin polyester self-laminating label
Clear-tail self-laminating construction; the 66.68 mm long format carries long ID numbers and long barcodes on a single label; after folding, it protects the printed content and leaves a clear window for liquid-level observation. Passes all four tiers from -196 °C LN₂ to 121 °C autoclaving.

Product Overview
Lab121-459 is a laboratory label made with ultra-thin polyester (PET) face stock and a clear-tail self-laminating construction, nominal size 66.68 × 15.24 mm (imperial 2.625″ × 0.6″), packaging 500-1000 labels/roll. The official material guide positions T459 as "an ultra-thin polyester label with a clear tail self-laminating construction that protects printed content and leaves a clear window for observing the liquid level." Temperature coverage spans all four tiers: LN₂ -196 °C, freezer -80 °C, hot water 100 °C, and autoclaving 121 °C. The application range checks both "cryovial/test tube" and "cell" columns. Self-laminating means the label carries a clear tail: after printing the variable fields, the clear tail is folded over the printed surface and pressed down, so the thermal-transfer ribbon layer is fully covered by the clear film and does not rub directly against the outside, while a clear area remains for observing the liquid level in the tube. The 66.68 mm long proportion lets the "print area + clear tail" fit on a single label, so one label accommodates a long specimen ID and a long barcode without truncation. Printing is matched with BRL-80-BK / BRL-110-BK laboratory cryogenic ribbons, compatible with M611, EOS2/3, and MACH4S laboratory label printers.
Key Features
覆
Clear-tail self-laminating protection
After printing, fold the clear tail over and press down; the printed surface is fully covered by the film layer, so the thermal-transfer print is not directly exposed; resistant to scuffing under repeated freeze–thaw handling and ethanol wiping (official wording: protects printed content).
窗
Clear liquid-level observation window
The clear tail covers only the print area; the clear section of the label stays transparent, so the liquid level can be read directly when applied to the tube wall; sample remaining volume can be judged in the tank without removing the cap (official wording: leaves a clear window for observing the liquid level).
幅
66.68 mm long-format capacity
The 66.68 × 15.24 mm (imperial 2.625″ × 0.6″) long proportion fits a long specimen ID and a long barcode horizontally, with no need to shrink fonts or cut fields to save space; one label per tube, no overlapping.
档
All four temperature tiers passed
The official table checks all four tiers: LN₂ -196 °C, freezer -80 °C, hot water 100 °C, and autoclaving 121 °C. From ultra-low temperature storage to autoclaving, one label follows the sample throughout without relabeling.

The product name mentions "conical tubes," but the official material guide checks the "cryovial/test tube" and "cell" columns for T459 and does not check conical tubes; this page follows the official table. Conical tube surfaces are an irregular-surface application; we recommend proofing first to verify conformability. The product page specification section lists "Material No.: self-laminating series" without a T459 material number; the specification table is completed per the official table.
Typical Applications
Long ID labeling on tube body
The 66.68 mm width fits a long "batch-project-serial" ID in one line, applied flat on the tube body without wrapping or overlapping; after the clear tail is folded over, the ID section is protected by the film layer and shows no scratches from handling in the LN₂ tank.
Direct liquid-level reading
The clear section left by the label aligns with the liquid-level zone on the tube wall, so the liquid level and sample remaining volume can be judged in the tank without opening the lid, reducing temperature disturbance from repeated opening.
Cell specimen labeling
The official table checks the "cell" application column; one label covers the entire labeling of cell cryovials from preparation and temporary storage in the -80 °C freezer to long-term storage in LN₂, with no relabeling or supplementary labels needed.
FAQ
Q: How do I apply the self-laminating label correctly?
A: First print the variable fields, then fold the label's clear tail over the print area and press it flat and firm. Covering the printed content with the clear tail is the core action of this label; without folding, the film protection and window division lose their purpose.
Q: Does the clear window affect barcode scanning?
A: The clear section is outside the print area; both the barcode and ID fall on the white printed surface, and the scanner reads the opaque area. When applying to the tube, align the barcode area with a flat part of the tube body and avoid curved transitions.
Q: Can it be autoclaved with the container?
A: The official table checks all four temperature tiers for T459, including 121 °C autoclaving, so it can go through the sterilization process with the container. This is the key difference from T509 (121 °C not checked) and T419, T329 (-40 °C only).
Q: Can it be used on conical tube surfaces?
A: The product name mentions "conical tubes," but the official table does not check the conical tube column for T459's application range, only cryovial/test tube and cells. Conical surfaces are an irregular-surface application; we recommend requesting a sample and proofing to verify conformability before bulk ordering.
Q: What ribbon and printer are needed for printing?
A: Matched with BRL-80-BK or BRL-110-BK laboratory cryogenic ribbon, compatible with M611, EOS2/3, and MACH4S laboratory label printers; before finalizing the long barcode section, we recommend a test print to confirm scannability.
Selection & Usage Guide
- Need high information capacity per label with long IDs and long barcodes not truncated: this 66.68 × 15.24 mm model is a long format in the T459 family with ample horizontal capacity.
- Need small labels and long labels from the same roll: switch to Lab115-459 (9.53+65 × 9.53 mm combined format), one for the tube body and one for the cap or rack position.
- Need an economical -40 °C tier for routine freezing: switch to T419 (gloss white PET) or T329 (matte white PP).
- Need to wrap thin tubes without autoclaving: switch to the T509 vinyl wrap-around model; need all-scenario general use for room temperature/microscope slides/conical tubes: switch to the T629 nylon cloth label.
- Before labeling, wipe oil, dirt, and moisture from the tube body; press firm after folding the clear tail; final performance at low temperatures is subject to actual proofing results.
Usage Notes
Note: The product name mentions "conical tubes," but the official material guide does not check the conical tube application column for T459; please proof first to verify conformability on conical tube surfaces. For ultra-low temperature applications, increase the contact area between label and tube wall, and press firm after folding the clear tail. The specification section lists "Material No.: self-laminating series" without a T459 material number; before bulk ordering, please confirm the latest material specification and shipping dimensions with customer service.
