Low Temperature · Cryogenic Storage

E-4812 — −196°C LN₂ Cryogenic Storage Label

−196°C liquid-nitrogen storage · direct-apply to frozen surfaces · up to 10 freeze-thaw cycles

Overview

Purpose-built identification labels for frozen laboratory sample containers — polypropylene (PP) cryovials, test tubes and storage boxes (PP and cardboard). Rated for storage from −150°C to −196°C (liquid-nitrogen environments), it keeps information clearly legible across the sample's entire frozen-storage lifecycle. It also survives repeated thaw-and-refreeze cycles — up to 10 cycles of thawing at room temperature or in warm / ice water followed by refreezing.

Features

Ultra-low-temp direct application: 7 N initial tack lets you label frozen surfaces directly — no need to thaw the sample, for a simpler, faster workflow.
Strong adhesion retention: stays firmly bonded through long-term liquid-nitrogen storage without loosening or falling off, preventing sample mix-ups.
Withstands up to 10 freeze-thaw cycles: wide temperature tolerance means no cracking, peeling or degradation across repeated cycles, keeping the mark intact.
Broad facestock compatibility: waterproof, oil-resistant and chemical-resistant, compatible with multiple print methods. For variable data, pair a thermal-transfer printer with an ultra-low-temperature resin ribbon for crisp, durable print.

Benefits

No warm-up needed — label directly at −80°C or in liquid nitrogen without thawing, so the sample never has to return to room temperature and its viability and integrity are protected.
Stays firmly attached — through long-term liquid-nitrogen storage the label stays bonded and never lifts, preventing mislabeling and sample mix-ups and safeguarding traceability.
Survives repeated freeze-thaw — withstands up to 10 freeze-thaw cycles, keeping identification clear and intact even after the sample is retrieved and refrozen many times.
Clear, durable data — thermal transfer with an ultra-low-temperature resin ribbon keeps information legible across the entire frozen lifecycle, reducing manual-checking errors.
