Direct Thermal Cryogenic Labels

Ensure sample traceability across demanding cold-chain workflows with Direct Thermal Cryogenic Labels. Engineered for biological specimens, chemical compounds, and clinical research samples, these labels withstand extreme cold environments ranging from -196°C (-321°F) in liquid and vapor phase nitrogen up to 93°C (+199°F). Because they utilize direct thermal printing technology, these labels require no ribbons or inks, delivering rapid, high-contrast barcode and text imaging directly onto blank label rolls.

Available in an array of vibrant color options and roll formats, these blank cryo labels allow laboratories to implement standardized visual color-coding alongside sharp 1D/2D machine-readable barcodes.

Versatile Applications Across Laboratory Environments

Designed to adhere reliably to polypropylene vials, glass containers, and plastic labware, these direct thermal labels support high-density identification throughout critical storage and testing protocols:

• Biobanking & Biorepository Tracking: Maintain long-term sample integrity on cryovials, microtubes, cryo boxes, and freezer racks and totes without label detachment or barcode degradation.

• Cell Culture & Cryopreservation: Label stem cells and blood specimens undergoing controlled-rate freezing, deep freeze, and rapid liquid nitrogen submersion.

• IVF & Specimen Processing: Accurately tag microcentrifuge tubes, laboratory equipment and retrieval containers with patient identifiers and unique serialization codes.

• Visual Identification & Color-Coding: Utilize multiple color variations (such as blue, green apple, red, yellow, orange, and white blank labels) to distinguish specific study groups, biosafety hazard levels, collection dates, or temperature sensitivities at a glance.

Engineered for Cryogenic Durability

Laboratory cold storage exposes labels to physical stress that degrades standard adhesives and facestocks. These direct thermal cryo labels are manufactured to maintain dimensional stability and print legibility under harsh conditions:

• Freeze-Thaw Resilience: Formulated with an aggressive, medical-grade cryogenic adhesive that resists edge lift, flagging, or cracking during repeated freeze-thaw and centrifuge cycles.

• Moisture & Condensation Defense: Retains permanent adhesion even when containers form surface frost or condensation upon removal from ultra-low temperature freezers.

• Surface Resistance: Specially coated facestock protects printed barcodes against ambient laboratory moisture, handling abrasion, and routine wiping with sopropyl alcohol (IPA).

Direct Thermal Printer Compatibility 

By eliminating the need for thermal transfer ribbons, direct thermal printing reduces supply waste, speeds up benchtop labeling workflows, and prevents ribbon-wrinkle errors in fast-paced lab settings:

• Direct Thermal Printing: Requires only heat-activated printing- no ribbons, toners, or ink cartridges needed.

• Universal Hardware Compatibility: Seamlessly prints with all major direct thermal desktop and industrial label printers, including the Zebra ZD421 Direct Thermal Printer compatible systems.

• Core Sizes for Every Setup: Offered on both 1-inch cores and 3-inch printer cores.

• High-Density Barcode Legibility: Produces sharp imaging optimized for scanning with standard handheld and automated laboratory barcode readers.
