We have integrated RFID technology into our cryogenic labels for frozen tubes and vials to develop our RFID CryoSTUCK® labels. The combination of these durable cryo labels with a flexible UHF inlay ensures that plastic and glass vials and tubes can be efficiently labeled under deep-freeze conditions, and that the recorded visual and electronic identification is securely protected, for maximum sample and data integrity.

RFID CryoSTUCK labels were specifically designed to withstand short and long-term sample storage in liquid and vapor phase liquid nitrogen (-196°C/-321°F), lab freezers (-80°C/-112°F), and transportation on dry ice. They can also withstand temperatures up to +100°C (+212°F) in wet and dry environments, making them suitable for identifying tubes* immersed in 37°C or 56°C water baths* (can be readable up to 1.5″/38 mm immersion**). These cryogenic RFID labels for frozen surfaces are intended for bio-banking, bio-repositories, research organizations, biopharmaceutical companies, hospitals, biotechnology and cancer research centers, molecular diagnostic laboratories, and any facility where frozen sample identification is needed.

Our UHF RFID labels for frozen surfaces can be printed and encoded using dedicated RFID thermal-transfer printers. When printed with our recommended smudge-proof RR-class of ribbons, the printout obtained is resistant to most common laboratory alcohols. The passive UHF RFID chip (Class 1, Gen 2) can be encoded with up to 32 hexadecimal characters of information. RFID CryoSTUCK labels are compatible with handheld, fixed, integrated, and cryogenic (Dewar neck) UHF RFID readers. Furthermore, they can be integrated with laboratory information management systems (LIMS) to improve sample identification and traceability, as well as to enhance process efficiency to comply with various regulations. RFID CryoSTUCK labels can also be hand-written with our cryo-markers. On vials and tubes, it is recommended that these CryoSTUCK labels are applied with an overlap of at least 0.45″ to ensure proper adherence to the frozen surface.

RFID CryoSTUCK label size can be customized upon request.


  • The labels can adhere quickly to already frozen vials and tubes (no thawing required)
  • Flexible UHF antenna and adhesive for frozen containers allow excellent adhesion, especially on curved surfaces (cryo vials, microcentrifuge tubes, and conical tubes)
  • Ideal for cryogenic storage**, no lag time when scanning/reading multiple items at the same time
  • Ideal for safely thawing in heated water baths**
  • 12” omnidirectional read range***ensures quick, easy, and accurate reading from every angle, without direct line-of-sight required

* Prior testing of these labels on the end user’s vials/tubes is strongly recommended.

** Labels should not be enclosed by metal surfaces as this may cause interference that can affect their ability to be scanned/read.

*** When using our recommended RFID reader. Read range can vary according to the RFID reader being used.

Frequently asked questions

Yes, thermal RFID CryoSTUCK® labels require a thermal-transfer ink ribbon to achieve the proper printout. These labels require an RR-class ink ribbon of the same width or larger, suitable for the RFID thermal-transfer printer being used.

No, RFID CryoSTUCK labels are not available in sheet format. For our Laser CryoSTUCK labels, click here.

RFID CryoSTUCK labels can be printed in most common thermal-transfer printers, but for simultaneous RFID encoding, you will require a thermal-transfer printer capable of RFID encoding.

Yes, an RFID printer can accurately print and encode these labels when printing. We recommend the Zebra ZD621R UHF RFID thermal-transfer printer.

You can design your own template that corresponds to the size of the label using specialized software such as BarTender Pro and ZebraDesigner3 Pro. which allow you to encode the RFID tags as well.

Please consult our handy sizing guide, where you will find recommendations for the most common vial/tube sizes.

Yes, RFID CryoSTUCK labels have been specially designed for the purpose of labeling already frozen vials and tubes. These cryogenic labels can be applied at -80°C/-112°F, eliminating the need to thaw valuable samples.

No, the vials can be stored in liquid nitrogen (-196°C/-121°F) or ultra-low temperature freezers (-80°C/-112°F) immediately following label application, requiring no cure time.

Yes, RFID CryoSTUCK labels can be used to label samples prior to storing them in low-temperature freezers and liquid nitrogen tanks

No, RFID CryoSTUCK labels have an extra-permanent adhesive that is not made for easy removal. For removable cryogenic solutions, see here.

No, these RFID labels are not compatible with automated print-and-apply systems.

Yes, an RFID reader is required to access the encoded data. It can be handheld, fixed, integrated, and cryogenic (Dewar neck). We recommend the Unitech Handheld UHF RFID Reader for mobility, reach, and ease of use. This reader can read the UHF RFID chip and scan 1D and 2D barcodes.

RFID CryoSTUCK labels can be read while the samples are immersed in the liquid phase of liquid nitrogen as far as 5″ deep when stored in plastic or temporary storage containers. However, they cannot be read while inside liquid nitrogen tanks or surrounded by metal. Prior testing of RFID readability in deeper immersion in liquid nitrogen is strongly recommended.

Yes, RFID CryoSTUCK labels are resistant to immersion in 37°C and 56°C water baths for thawing, incubation, and inactivation of samples and reagents. They can also be read while the labels are immersed up to 1.5″/38 mm into the water bath. Cryo vials should ideally be towards the middle of the water bath, away from the metal sides. Prior testing of RFID readability while immersed in other liquids is strongly recommended.

Yes, these RFID labels (RF3-L2FSA class labels) will resist elevated temperatures, up to +100°C (+212°F) in dry and wet environments. Thus, in addition to labeling your frozen tubes, you can also use your RFID CryoSTUCK labeled tubes in procedures that require high heat incubation.

No, these labels employ UHF RFID technology and thus can be interrogated in another band frequency apart from NFC RFID labels. Thus, a dedicated UHF RFID reader is needed. For CryoSTUCK labels customized with NFC RFID technology, contact our technical support team.

Place the UHF RFID reader at a maximum of 12″ (30.5 cm) away from the sample in any direction. However, the read range can vary according to the UHF RFID reader being used.

Yes, RFID CryoSTUCK labels are compatible with both regulations. Interrogate these labels with a UHF reader capable of reading the frequency band.

The UHF RFID chip (Class 1, Gen2) of the RFID CryoSTUCK labels can be encoded with up to 32 hexadecimal characters.

Yes, RFID CryoSTUCK® contain read-write UHF RFID chips. Thus, you can rewrite the EPC memory bank up to 100,000 times if the permalock feature is not active.

Yes, you can scan/read multiple RFID CryoSTUCK labels at the same time within the interrogation timeout (in seconds), even without a direct line-of-sight to the UHF RFID reader.

No, RFID CryoSTUCK labels are battery-free. They do not require a battery to be functional as they employ passive RFID technology.

No, we do not recommend our RFID CryoSTUCK labels for this purpose. To cover-up existing labels, our blackout CryoSTUCK labels will conceal pre-existing information, while our clear CryoSTUCK labels can be applied over an existing label, acting as a laminate to reinforce it. For RFID CryoSTUCK labels suitable to be applied over existing labels, contact our technical support team.

Yes, we can provide our RFID CryoSTUCK labels preprinted with full-color graphics and logos, as well as variable or serialized information from a database. Please consult our technical support team for details regarding custom encoding and other custom printing options.

For optimal adhesion, wipe away any visibly accumulated frost with a clean lint-free disposable wipe (e.g., KimWipe™). Apply the edge of the label first and press firmly to anchor it while avoiding excessive contact with the adhesive. If you have a wrap-around CryoSTUCK, apply the printable area first. Then press the label securely into position along the vial’s entire circumference. These thermal-transfer RFID CryoSTUCK labels (RF3-L2FSA-class labels) require an overlap of least 0.45″ to produce a secure adhesion to frozen vials and tubes.

Yes, RFID CryoSTUCK labels (RF3-L2FSA-class) are suitable for flat surfaces, including cryogenic storage cardboard boxes, requiring no overlap during application.
