Lab270-429-5D / Ø9.53 mm — Matte White PET Low-Temp Labels for Biobank Cryovials & Slides

Lab270-429-5D belongs to the BRD博锐迪 T429 polyester cryogenic label series, using matte white PET polyester film as the face stock, with a nominal size of 9.53 mm; the page image shows full-roll circular dot-matrix die-cutting. It is compatible with a four-stage temperature chain: -196 °C liquid nitrogen, -80 °C freezers, 100 °C hot water, and 121 °C autoclaving. The micro dot format is designed for small-area point labeling such as tube cap tops and cryobox grid positions, suitable for batch archiving management in biobanks.

Product Overview

Lab270-429-5D is a laboratory cryogenic label using matte white PET polyester film as the face stock, coated on one side with cryogenic adhesive, capable of maintaining adhesion and legibility from -196 °C liquid nitrogen 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 the ends when applied to frozen tube surfaces. This product is full-roll dot-matrix die-cut at a nominal diameter of 9.53 mm (per the page product image), with continuous feed per roll and no cutting required; a single dot label precisely covers one tube cap top surface or one grid position, suitable for point-number management of batch specimens. Due to the small dot area, printed content is mainly short numbers, color dot codes, or dot positioning, forming a two-level identification system together with rectangular labels on cryovial bodies.

Key Features

• Full four-stage temperature chain: T429 has passed testing at -196 °C liquid nitrogen, -80 °C freezer, 100 °C hot water, and 121 °C autoclaving; point labels accompany specimens through the complete freeze–thaw and autoclaving process.
• Micro circular dot format: 9.53 mm dot labels match the top surface dimensions of common cryovial caps; full-roll dot-matrix die-cutting enables continuous feed in a single pass, peel and apply, with no manual cutting required.
• High point-labeling efficiency: 500–1000 labels per roll, suitable for batch point scenarios such as cryobox grid positions, tube cap tops, and plate well positioning; faster and more uniform than handwritten marks.
• Frozen surface overlap rule: when labels are used for wrapping or edge/corner application on frozen surfaces, overlap at least 3 mm at the ends to ensure no lifting or detachment after repeated ultra-low temperature handling.
• Complete compatibility: recommended BRL-80-BK / BRL-110-BK cryogenic ribbons, used with M611, EOS2/3, MACH4S laboratory label printers.

Typical Applications

• Cryovial cap point labels: applied to the cap top surface to carry short numbers or color dot codes, complementing body labels; top information can be identified without removing vials from the cryobox rack.
• Cryobox grid position marking: 9.53 mm dot labels match grid dimensions, used for box lid grid numbering or empty-position marking, supporting specimen storage location management.
• Biobank packaging identification: the official material table checks T429 under the "packaging identification" dimension, suitable for cryobag sealing, point seals on transport box exteriors, and batch short codes.
• Microtube small-area labeling: Eppendorf tubes and micro cryovials have limited body space; dot labels occupy little area and can carry a single code without obscuring graduations or liquid level.

FAQ

• What does the "-5D" suffix on Lab270-429-5D mean? Neither the page nor the parameter section specifies its meaning (it is not a material code or specification); before purchase, confirm the specific die-cut and slitting format with customer service.
• Can 9.53 mm dot labels print barcodes? The dot diameter is limited; it is recommended to use only short numbers, batch codes, or color dot positioning. For full barcodes, use the 25.4 × 9.53 mm strip Lab062-429 or the combination format Lab038-429.
• How does it differ from the Lab111-629-10A circular label? Lab111-648 is Φ13 mm circular in T629 nylon cloth material; this product is 9.53 mm in T429 polyester material, with a smaller diameter and different face stock. Choose based on cap dimensions and temperature chain.
• Can it be applied to microscope slides? The official application scope of T429 covers cryovials/test tubes and packaging identification, with microscope slides not checked. The "microscope slide" in the page name is inconsistent with the official table; for microscope slide scenarios, use T629 nylon cloth labels instead.

Selection & Usage Guide

Lab270-429-5D is positioned as a "micro circular dot point label." When selecting, first confirm the carrier surface dimensions: choose this product for tube cap tops or cryobox grid positions; for full barcodes choose Lab062-429 strip; for simultaneous body and cap dual-zone printing in one pass choose Lab038-429 combination format; for batch tube labeling choose Lab169-429 three-column die-cut; for multi-line information choose Lab014-429 or Lab102-429. For room-temperature freezing environments above -40 °C only, the economical T419/T329 models can be used; for pathology solvent-resistant scenarios, use T424 with BRS series ribbons; for full coverage including microscope slides and conical tubes, choose T629 nylon cloth. When applying to frozen tube surfaces, remember the official 3 mm end overlap rule, which significantly reduces the risk of edge lifting at ultra-low temperatures. Before running, it is recommended to pre-feed the entire roll once to reduce dot-matrix die-cut edges being lifted or causing jams during printing.

Usage Notes

Note: The page name includes "microscope slide," but the official application scope of T429 does not check microscope slides; for actual slide scenarios, use T629/T424 instead. The "-5D" suffix and the "adhesive" wording are subject to the page image and official material table; before ordering, contact customer service to verify the die-cut format.
