These new PikaTAG® cryogenic dot labels for indented caps are provided with a corresponding rectangle making it possible to identify the indented caps of cryo vials (1 to 5 mL) as well as the side of the container. The dots are designed to work with our innovative PikaTAG applicator, allowing the circle labels to be quickly picked up and easily applied into indented-cap style cryo vials, such as Nunc™ #375418, Nalgene®️ #5000-0020, Corning™️ #430488, Simport®️ #T301, T308, T309, T310, and T311, and other similar vials. The corresponding rectangular label can be applied on the side of the vial as usual. These cryo labels will adhere to wet surfaces and are designed to withstand extended low temperature sample storage in vapor phase and liquid phase liquid nitrogen (-196°C/-321°F), lab freezers (-80°C/-112°F), and dry ice transportation.

These cryo labels afford the greatest flexibility in high-throughput applications that demand cap and side labeling, such as clinical trials, diagnostics, biobanking, epidemiological studies, basic research, and kit manufacturing. Thermal-transfer printable, as well as hand writable with our cryo markers. Barcoding software can also be used to easily encode and print 1D/linear or 2D barcodes. The labels can then be affixed onto the caps and sides of indented tubes, allowing them to be scan/read for maximum versatility and control of information.


  • Conveniently label the indented-cap and side of cryo vials (1 to 5 mL) for cryogenic storage (-196°C/-321°F)
  • Compatible with automated high-throughput sample storage and handling systems
  • Require zero cure time, can be immersed in liquid nitrogen immediately following application
  • Adhere to wet surfaces
  • Dot labels are compatible with cryo vial removal tool

Recommended Ribbons: RR-Class Smudge and Alcohol Proof Resin Ribbons

Frequently Asked Questions

These PikaTAG dot labels are compatible with 1 to 5 mL cryo vials, especially indented-cap style ones such as Nunc®️ #375418, Nalgene®️ #5000-0020, #5000-0012, Corning™️ #430488, Simport®️ #T301, T308, T309, T310, and T311.

Place a soft surface, for example, a notebook or mouse pad, underneath the label’s support liner/backing.

Yes, these dot labels are fully compatible with cryo vial picking, gripping, and removal tools.

Yes, you can use PikaTAG labeled cryo vials with manual, semi-automated, and automated decapping machines.

Yes, a 2D barcode (i.e. QR Code or Datamatrix) fits perfectly and can be scanned on these 0.354” / 9 mm circle labels.

Yes, PikaTAG dot labels are compatible with automated tube and vial handlers for maximum versatility and control of identification. (not suitable for automated print and apply labeling systems)

Yes, the PikaTAG applicator has replaceable tips. We offer refill tip sheets, that make replacing the tips quick and easy.

Each tip can be used to apply, on average, about 100 dot labels, after which it should be replaced, using one of our convenient refill sheets.

Yes, PikaTAG dot labels are thermal-transfer printable and require a ribbon to be printed. To achieve the proper printout, these labels require the use of our  RR-class ribbons of the same width or larger. These labels can also be written on using our MP-1 and F-1 cryo markers.

No, these labels are best applied at room temperature prior to storing them in a cryogenic environment. For labeling already frozen vials, we recommend CryoSTUCK® labels, a line of cryogenic labels specially designed for that purpose.

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.

No, PikaTAG dot labels have a permanent adhesive, that is not made for easy removal.
