Lab313-429 / 13 × 6 mm, 3-up — PET Polyester Low-Temp Labels for Laboratory Cryovials & Slides

Lab313-429 belongs to the BRD博锐迪 T429 polyester cryogenic label series. It uses matte white PET polyester film as the face stock, measures 13x6mm, and is one of the smallest rectangular formats by nominal area in this family. It is compatible with the four-tier temperature chain of -196℃ liquid nitrogen, -80℃ freezers, 100℃ hot water, and 121℃ autoclaving. The ultra-small format is designed specifically for labeling micro cryovials, narrow containers, and very short code positions, and is suitable for refined archiving in biological sample banks.

Product Overview

Lab313-429 is a laboratory cryogenic label made with matte white PET polyester film face stock and a single-side cryogenic adhesive coating, capable of maintaining adhesion and legibility from -196℃ liquid nitrogen to 121℃ autoclaving. The official material guide positions T429 as "the ideal choice for labeling frozen surfaces" and specifies a minimum 3mm overlap at both ends when applied to frozen tube surfaces. This item is die-cut into an ultra-small 13x6mm rectangle (the product image on the page shows a full roll of small rectangular labels), and each label accommodates only a single line of a short number, short code, or color code. With an area of less than 0.8 square centimeters, it takes up almost no space when applied to microtube walls, plate well edges, or box grid corners, making it suitable for sample cohorts that are extremely sensitive to label size. After printing, content remains intact and legible through long-term storage at -80℃ and autoclaving at 121℃.

Key Features

• Full four-tier temperature chain: T429 has passed testing at -196℃ liquid nitrogen, -80℃ freezer, 100℃ hot water, and 121℃ autoclaving, covering the complete workflow from ultra-low temperature storage to rewarming and autoclaving.
• Ultra-small rectangular format: the 13x6mm area is extremely small, designed for microtubes and narrow positions, and does not obscure tube graduations, liquid levels, or existing printed information after application.
• Continuous full-roll feed: the page image shows a full roll of small rectangular labels, 500-1000 labels/roll, ready to peel and apply in batch operations without cutting.
• Frozen-surface overlap rule: when applied to frozen flat surfaces or wrapped, overlap at least 3mm at both ends to prevent edge lifting or adhesive failure during repeated ultra-low temperature handling.
• Complete system compatibility: recommended BRL-80-BK / BRL-110-BK cryogenic ribbons, used with M611, EOS2/3, and MACH4S laboratory label printers.
• Matte white print surface: the matte white PET face stock combined with cryogenic ribbons provides high print contrast, and short numbers and dates remain clearly scannable under ultra-low temperature conditions.

Typical Applications

• Micro cryovial labeling: narrow-band labeling on the walls of 0.5mL/0.2mL microtubes and small-diameter cryovials, carrying a single line of short numbers without obscuring liquid levels or graduations.
• Plate well and grid position codes: single-line short code positioning at the edges of 96-well plates and corners of cryobox grids, corresponding one-to-one with samples in the plate.
• Sample bank packaging identification: the official material table checks T429 for the "packaging identification" dimension, suitable for small-area seals such as short codes on cryobag seals and corner marks on transfer boxes.
• Long-cycle archiving of cohort samples: with years of -80℃ freezer storage combined with 100℃ rewarming and 121℃ autoclaving chains, labels remain functional throughout the sample lifecycle, suitable for continuous archiving and batch traceability in long-term cohort projects.

FAQ

• What does "-3L" in the name Lab313-429 mean? Neither the page name nor the parameter section specifies the meaning of this suffix (it is neither a material code nor a nominal dimension). Before ordering, confirm the die-cut or slitting format with customer service.
• Can 13x6mm print a barcode? The format accommodates only a single line of a short number or short code. For a complete 1D barcode, we recommend the 25.4x9.53mm strip Lab062-429 or the 25x10mm Lab094-429.
• How to choose between this and Lab336-429 (25x5mm)? Lab336-429 is a 5:1 ultra-narrow strip with dual-column roll feed; this 13x6mm item is closer to square and smaller in area. Choose based on container width and information length.
• Can it be applied to microscope slides? The official application scope of T429 covers cryovials/test tubes and packaging identification, and does not check microscope slides. The "microscope slide" mention in the page name is inconsistent with the official table; for slide applications, we recommend switching to T629 nylon cloth labels.

Selection & Usage Guide

Lab313-429 is positioned as an "ultra-small rectangular minimalist position label." When selecting, first confirm the information volume: for a single line of short numbers only, choose this item; if both a number and a barcode are required, switch to Lab094-429 or Lab062-429; for round dots on tube caps, choose Lab270-429-5D; for batch tube labeling, choose the Lab169-429 three-column die-cut; for full multi-line information, choose Lab014-429 or Lab102-429. For room-temperature freezing environments above -40℃ only, the economical T419/T329 models can be used; for pathology solvent-resistant scenarios, switch to T424 with BRS series ribbons; for full coverage of microscope slides, conical tubes, and other scenarios, choose T629 nylon cloth. For ultra-small format printing, we recommend increasing the minimum font size and leaving sufficient quiet zones to avoid scanner recognition difficulties. If the sample container has a large curved surface or requires wrap-around coverage, we recommend small-batch proofing first to verify the 6mm label height's conformity on curved surfaces before full-scale production.

Usage Notes

Note: The page name mentions "microscope slide," but the official application scope of T429 does not check microscope slides. For actual slide scenarios, we recommend switching to T629/T424. The meaning of the "-3L" suffix is not specified on the page; contact customer service to verify the die-cut and slitting format before ordering.
