Combining RFID technology and our thermal-transfer printable cryogenic labels into one product, RFID NitroTAG® labels are the first cryogenic RFID labels that can be used in liquid nitrogen. They can be printed and encoded using dedicated RFID thermal-transfer printers. Their flexible, passive UHF RFID chip (Class 1, Gen 2) can be encoded with up to 32 hexadecimal characters of information to record data during sample processing. The resulting label can thus contain both visual and electronic data for maximum sample tracking flexibility.

RFID NitroTAG labels are specifically designed for short and long-term storage under ultra-low temperatures and cryogenic environments, including liquid and vapor phase liquid nitrogen (-196ºC/-321°F), lab freezers (-80°C/-112°F), and dry ice transportation. They have a strong permanent adhesive to ensure they will stay affixed on cryo tubes & vials*, cardboard and polypropylene cryo/freezer boxes, plastic bags, and triangular cassettes for straw storage. They can be scanned/read without the need for direct line-of-sight, even when in liquid nitrogen** or immersed up to 1.5”/38mm*** in a 37°C water bath. This can help eliminate unwanted freeze-thaw cycles, thus preserving the samples’ integrity. They are ideal for biobanks, biorepositories, fertility clinics, and crystallography laboratories.

These RFID labels are compatible with handheld, fixed, integrated, and cryogenic (Dewar neck) RFID readers. Moreover, they can be integrated with electronic witnessing systems to improve the identification and traceability of samples, as well as workflow efficiency to comply with audits. The printout obtained is also resistant to alcohol spraying/swabbing and sanitizing wipes when printed with our recommended smudge-proof RR-class of resin ribbons.

RFID NitroTAG label size can be customized upon request.

Benefits:

  • 12” omnidirectional read range***ensures quick, easy, and accurate reading from every angle
  • Scan multiple cryogenic containers at the same time, even without a clear line-of-sight**
  • Flexible UHF antenna and cryogenic adhesive allow permanent adhesion, especially on curved and wet surfaces without the need for a curing period
  • Ideal for liquid nitrogen storage, no lag time when scanning/reading items
  • Labels are resistant to spraying and swabbing with alcohol and surface sanitizing wipes

* Prior testing of these labels on 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, RFID NitroTAG labels are thermal-transfer printable and require an ink ribbon to be printed. To achieve the proper printout, these labels require an RR-class ink ribbon of the same width or larger.

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

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

No, RFID NitroTAG labels has a permanent adhesive that is not made for easy removal.

Yes, RFID NitroTAG labels can be offered in a variety of colors. For more information, contact our technical support team.

No, please contact us for our complete customization options.

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

Yes, a UHF 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 is able to read UHF RFID chips and scan 1D and 2D barcodes.

RFID NitroTAG 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, specialized software is required to properly encode your labels. We would recommend BarTender Pro and ZebraDesigner3 Pro.

Barcoding or label design software can be used to create templates that conform to the size of your label. You can then insert design elements within the template for easy printing.

Yes, we can provide our RFID NitroTAG labels preprinted with full-color graphics and logos, as well as variable or serialized information from a database. Learn more about our custom printing options.

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 RFID reader being used.

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

Yes, RFID NitroTAG labels contain read-write UHF RFID chips. Thus, you can rewrite the UHF RFID chip’s memory bank (EPC, TID, and user) up to 100,000 times if the permalock feature is not active.

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

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

No, RFID NitroTAG labels are battery-free. These labels don’t require a battery to be functional because they employ passive UHF RFID technology.

Yes, although these labels are intended for vials, tubes, and boxes. For identifying plates and dishes with RFID, we recommend our RFID-PlateTAG™ labels.

No, RFID NitroTAG labels are best applied at room temperature. For labeling already frozen vials and tubes, we recommend CryoSTUCK® labels, a line of cryogenic labels specially designed for that purpose. Please, contact us for customization options.

RFID NitroTAG labels can be read while the samples are in liquid nitrogen (i.e., in a plastic, temporary storage container), but the cryo vials cannot be surrounded by metal, for example, when placed inside a liquid nitrogen tank.

RFID NitroTAG labels can be read while the labels are immersed up to 1.5”/ 38 mm in a 37°C water bath. Cryo vials should ideally be towards the middle of the water bath, away from the metal sides.

No, RFID NitroTAG labels are not designed for metal surfaces. Please contact us for metal surface RFID identification solutions.

Please consult our technical support team. for details regarding custom encoding and other customization options.

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 NitroTAG labels customized with NFC RFID technology, contact our technical support team.

Great Budget Earbuds That Have Held Up Well
Style: Standard, Color: Black
I originally bought these earbuds because they were on sale and listed as an Amazon’s Choice product, and they’ve turned out to be a really good value. I’ve had them for about a year now, and they’ve held up without any issues. They connect to Bluetooth quickly and easily, the LED battery display on the front of the charging case is a nice feature, and the sound quality is surprisingly good for an inexpensive set of earbuds. Battery life has also been solid for everyday use. The microphone works fine for phone calls in quieter environments, although it doesn’t do much to block out wind noise if you’re outside. Still, for the price, these are impressive headphones and a great budget-friendly option. Overall, I’m very happy with them.

Get them!!!
Style: Standard, Color: Black
Run ...don't walk. These headphones are amazing. I was on the verge of giving up trying to find wireless headphones that could fit my small ears, be comfortable, have great sound quality, when listening to music and talking on the phone, cancel noise, that keep a decent charge, that don't fall out as I'm walking and moving my head, and are AFFORDABLE These headphones check ALL the boxes. There was a no fuss set up and pairing that took 2 min. I haven't charged them in 5 days and still have 33% charge left on them after listening to music for hours for days. They came charged as well. I've had much more expensive brands and they have failed me. These are IT and I will be purchasing them as gifts for friends and family.

Amazing buds/price/service... buy these!
Style: Standard, Color: Purple
Yes, my subject line sounds like that trash hyperbole you get on annoying pop-up ads on your Smartphone! And ironically, it usually has to do with ear buds. There are tons of them on the market, and everyone claims to be the best. Now, first off, I am just a customer… never got any gifts or money or anything from this company, nor was asked to “click on a review” for a discount or whatever. No… the reason for all this hallelujah chorus, is that I’m really totally both jazzed, and a bit in awe of these earbuds. I think the main mind-blowing thing about them is the price. I mean, I have a bit of experience and knowledge with this kind of technology, and frankly, these days, what “guts” that are needed to be used to create Bluetooth ear buds is not that complex… nor expensive. How company’s like Sony, Apple, Bose, etc. can charge upwards of $300 for these boarders on theft and fraud! I’ve tried those “Rolls Royce” buds, and I urge you to do the same, and then try these Tagry Bluetooth Wireless Earbuds that are literally 90% less expensive. Yes, they retail for about $35! They come in an excellent quality charge base, are extremely easy to put on, (and have three extra size buds to give you a custom fit), and most important, their sound quality, and I mean crisp highs, solid middles, and bone- rumbling base, are outstanding. I cannot understand what more you would want either using them for talk radio, podcasts, YouTube, streaming movies, or TV, or playing your Amazon Music or Spotify or iTunes playlists. And yes, if connected to your iPhone, you can make and receive calls, and the microphone in the buds are top quality. Their Bluetooth software is flawless, connecting to your iPhone, or other Bluetooth devices effortlessly. They come with a pleasant woman’s voice letting you know various messages, like which earbud is in what ear, if they are connected or turned off, your volume control (including excess volume warning), etc. I’ve had these for several months, and have found the charging, which has a bright LED display and shows the individual charging of each bud, along with their percentage easy to read. And a note on their service. I’ve heard horror stories of folks trying to reach the outrageously over-priced other earbud company’s for tech support, or refunds, exchanges, etc. Basically it’s nonexistent, and when you do miraculously find a phone number to call them, and get someone on the line, you have to go to the UN to find an interpreter of rare third-world languages to understand what they are saying, and they seem to be trained, not on anything to do with the product, but to make the call as useless and confusing as possible, so that you will just give up and throw their buds, and your money in the trash. Now, I did have an initial problem, after a few months, in that the base charger seemed to be slowing a bit. Tagry gives you a LIFETIME WARRANTY… yes, an actually lifetime warranty, not one of those sham “lifetime warranties”, that corrupt company’s like Hammacher Schlemmer have. I had enrolled with Tagry, on their website, to activate my warranty as soon as I received the buds. I called Tagry when I was seeing what could be a glitch in their charging base, and yes, unlike most other companies who hide their contact numbers as if they were nuclear codes, Tagry’s support phone number is plainly printed on their manual, and to my astonishment, I immediately was connected to a good ‘ol American customer service person, who actually worked for the company, spoke English, and made me feel as if I was a long-ago trusted friend. They truly cared, and said they were sorry, and that there was no need to troubleshoot the base, or return it, instead, they would process an order to send me a new one. A day later, they actually called me back to let me know that the replacement had been shipped, and that I should have it in a day or so, and if not, to please call them back right away. And yes, to apologize again for any inconvenience. The replacement arrived the very next day. And again, their warranty is indeed for a lifetime, a no questions asked replacement policy. This is how much they believe in their product, and respect their customers. So, yes. It is insane to pay more than $35 for quality Bluetooth earbuds. Last year, I sent about a dozen of these out to friends and employees, to use for personal use, and for all that Zooming going on… and they love them. And none of had any problems. I’m sure you have had a plethora of bad experiences in the past few years, what with isolation, and way too much ordering on-line, finding the products you buy to be substandard, and customer service virtually non-existent. And that is why I’ve spend all this time expounding on the greatest of my earbuds. Yes, I have a life. Really. But what a joy to be able to tell a story like this, rather than the kind of frustration most of us are experiencing every day! Yes, goodness and quality still exist. It’s rare… but it’s out there!

A big bang for your buck!
Style: Standard, Color: Pink, Style: Standard, Color: Pink
I waited a while to review. I wanted to see how they did overtime. These are amazing for the price. The sound is crisp and clear and even can go extremely loud if that's your thing. They fit comfortably in my ear and are durable (I've dropped them a few times). The case holds a charge for a long time they connect to Bluetooth with no problems. I only gave 4 stars because there is a slight delay when you tap the ear buds to change functions. It's also a small spot to touch and sometimes I find myself having to tap it a few times to find the right spot to turn on/off, turn volume up, change songs, etc. These are simple with great sound and an amazing price. If you're a sound connoisseur and want a equalizer board to work with these aren't for you. I have expensive Jabra ear buds and find I use these more. They fit better and I don't worry about losing them.

Great quality
Style: Standard, Color: Forest Green
Very surprised at the quality of these headphones. They’re comfortable in the ear and have very clear sound quality and great volume. They’re easy to set up and the ear bud is just the right size to sit comfortably. Settings are easy to adjust and the battery life is great. I will say the color doesn’t match to the display image, they’re a lot darker green, but that’s not really an issue. I just wanted to get a colorful pair to make them distinct from others. These are a great budget ear bud!!
