Lab038-429 / 25.4 × 9.53 mm + Ø9.53 mm — Matte White PET Labels for Biobank EP Tubes, -80 °C

Lab038-429 belongs to the BRD博锐迪 T429 polyester cryogenic label series. It uses matte white PET polyester film as the face stock and is compatible with a four-stage temperature chain: -196 °C liquid nitrogen, -80 °C freezers, 100 °C hot water, and 121 °C autoclaving. The 25.4 × 9.53 + Φ9.53 mm combination format includes a 25.4 × 9.53 mm rectangular main label and a Φ9.53 mm circular secondary label, so a single roll can separately label the body of cryovials/microcentrifuge tubes and the caps/rack positions without changing label rolls. It is suitable for biobanks, drug discovery, clinical laboratory testing, and other scenarios requiring long-term low-temperature traceability.

Product Overview

Lab038-429 is a laboratory cryogenic combination label made with matte white PET polyester film as the face stock and a single-side coating of cryogenic adhesive. It maintains adhesion and readability in environments ranging from -196 °C liquid nitrogen to 121 °C autoclaving. This model is produced according to the T429 polyester series process. The rectangular area is suitable for application to the bodies of cylindrical containers such as cryovials and microcentrifuge tubes, while the circular area is suitable for the top of caps or rack position posts, achieving "one label, two zones; one roll, two uses." When applying to frozen tube surfaces, an overlap of ≥3 mm at the ends is recommended to resist edge lifting caused by alternating hot and cold. Printed content remains clearly readable after long-term storage at -80 °C and 121 °C autoclaving, making it suitable for high-value samples that go through the complete cold chain and rewarming process.

Key Features

• Rectangular + circular combination format: the 25.4 × 9.53 mm rectangular main label carries barcodes/IDs, while the Φ9.53 mm circular secondary label is used for cap/rack position identification. One roll covers two labeling needs.
• 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, meeting the complete process from ultra-low temperature storage to rewarming and sterilization.
• One roll, two uses: two die-cut shapes are output from the same roll, avoiding frequent roll changes and improving batch archiving and review efficiency in sample banks.
• ≥3 mm overlap on frozen tube surfaces: when applied to frozen tube surfaces, overlap the ends by at least 3 mm to ensure edges and corners do not lift or fall off after repeated low-temperature handling.
• Complete matching system: recommended BRL-80-BK / BRL-110-BK cryogenic ribbons, used with M611, EOS2/3, and MACH4S laboratory label printers.

Typical Applications

• Biobanks: apply the rectangular main label to the body of cryovials and microcentrifuge tubes, and the circular secondary label to the top of caps, achieving dual-point traceability of tube body and cap; remains clearly readable after long-term storage at -80 °C.
• Drug discovery: low-temperature labeling of cell lines and reagent aliquot tubes; the combination format reduces roll changes and facilitates quick scanning on tube racks.
• Clinical laboratory testing: for sample chains that undergo 100 °C hot water rewarming or 121 °C autoclaving, printed content resists steam washing without blurring or falling off.
• Cryobox / cryorack zoning: the circular secondary label can be applied to the side walls of cryobox slots or rack position posts as a secondary position identifier outside the tube.

FAQ

• How is the combination format used? The rectangular main label is applied to the tube body to carry the sample ID and barcode, and the circular secondary label is applied to the cap or rack position; both are output from the same roll without changing rolls mid-process.
• What is the difference from Lab038-625? Lab038-625 is T629 nylon cloth material (liquid nitrogen focused, full-scenario), while Lab038-429 is T429 matte white PET (four-stage temperature, printing + handwriting dual mode); the material system and application temperatures differ.
• What is the difference from Lab062-429? Lab062-429 is a single rectangular strip format of 25.4 × 9.53 mm, labeling only the tube body; Lab038-429 adds a Φ9.53 mm circular secondary label on the same rectangular specification, enabling dual-zone labeling of tube body + cap/rack position.
• Can it be applied to microscope slides? The official application scope of T429 is cryovials/test tubes and packaging labeling; microscope slides are not checked. If microscope slide labeling is required, it is recommended to use T629 nylon cloth labels or T424 chemical-resistant labels.
• What are the low-temperature application requirements? When T429 is applied to frozen tube surfaces, overlap the ends by at least 3 mm; after opening the label roll, use it as soon as possible to avoid dust adhering to the adhesive surface and affecting low-temperature adhesion.

Selection & Usage Guide

Lab038-429 is positioned as "combination format, one roll, two uses," suitable for sample bank scenarios requiring simultaneous labeling of tube bodies and caps/rack positions. The combination format design reduces roll-change downtime and improves batch archiving efficiency. When selecting, first confirm the temperature chain the samples will undergo and the type of container, then decide the layout format. If only tube body labeling is needed, switch to Lab062-429; if a larger combination format is needed, switch to Lab142-429-2A (40 × 15 + 11 mm); if only above -40 °C is needed, switch to T419/T329; for microscope slides/conical tubes, switch to T629; for pathology solvent resistance, switch to T424 + BRS ribbon.

Usage Notes

Note: Although T429 covers four temperature stages, temperature resistance does not equal resistance to all chemical solvents. The page parameter section "Dimensions: see product details" is inconsistent with the name nominal 25.4 × 9.53 + Φ9.53 mm; the body text follows the name nominal. If samples will undergo the liquid nitrogen stage, ensure sufficient end overlap during labeling to avoid edge lifting at ultra-low temperatures.
