FAQ on CryoTek materials and Cryogenics
Cryogenics technically means a few degrees away from absolute zero degrees which is 0K on the Kelvin scale and as −273.15°C on the Celsius scale and as −459.67°F on the Fahrenheit scale. This is a theoretical value that in practice is not reached. Liquid Nitrogen which is used in Cryogenics exists between the temperatures of 63 K and 77.2 K
(-346°F and -320.44°F). Below 63 K, nitrogen freezes and becomes a solid. Above 77.2 K, nitrogen boils and becomes a gas. Since when liquid nitrogen is used in laboratories and in cryogenics it is in a boiling liquid state, it shows a temperature of 77.2 K. This is approximately -320 degrees Fahrenheit and -195.555556 degrees Celsius.
In practice, specimens may be submerged or held in the cryogenic vapor. In testing of our CryoTek material, vials were tested both ways and when frozen and thawed. Labels held throughout. See my earlier Blog post for more specifics on the testing that was done.
New Cryogenic Label Material
All-Tek has tested and approved its CryoTek® label material on glass slides and plastic vials in liquid nitrogen at -196°C (-320° F).
From time to time we all have run into applications that require a label material that will need to withstand and perform well in a cryogenic environment. In the past, we have had solutions but our new product, CryoTek®, has proven to be far superior.
CryoTek2® (2mil adhesive) and CryoTek1® (1mil adhesive) are 5 mil,
woven nylon material with a permanent pressure sensitive acrylic adhesive and high opacity matte white color topcoat. The nylon label is an ideal choice to adhere to vials, test tubes and other rounded surfaces due to its flexibility.
These two products also provide excellent chemical durability when exposed to harsh chemicals such as: Sulfuric acid solution, Sodium hydroxide solution and Mineral Spirits to name a few. CryoTek2® & CryoTek1® are designed for thermal transfer, dot matrix or write-on printing.
CryoTek1® has been tested and recognized to meet UL969 and CUL standards.

TESTING RESULTS
Test Objective:
Attach nylon label samples to glass slides and polyethylene cryogenic tube vials and immerse in liquid nitrogen for a period of one hour to determine if they adhere to the substrate during and after immersion.
Sample Information:

Figure 1
Testing Method:
The samples were immersed in liquid nitrogen (temperature is -196°C or -320°F).
The samples were monitored during immersion at 15 minute intervals until testing was completed.
The immersion period was for one hour.
Immediately after removal from the liquid nitrogen, each label was lightly probed with a stylus to determine if it was loose or easy to peel.
The samples were allowed to return to room temperature.
Test Results:
Samples A and B (plastic vials)
• During testing: all labels held firm
• Immediately after testing (still cold): all labels held firm
• At room temperature after testing: all labels held firm
Samples C and D (slides)
• During testing: all labels held firm
• Immediately after testing (still cold): all labels held firm
• At room temperature after testing: all labels held firm
