For more than three decades, the Thermo Scientific™ Nalgene™ and Nunc™ cryogenic tubes have been cool and dependable, from their industry-leading Sterility Assurance Level of 10-6 to the broad range of tubes for every application in your lab. And you know they're cool—they handle temperatures down to the vapor phase of liquid nitrogen (safely stored in Thermo Scientific Nunc Cryoflex™ tubing, of course).
Now we have even more cool stuff—like the Thermo Scientific Nunc Dense Storage Options that lets you store 169 tubes in the standard 5 x 5 in cryoboxes you already use! That's double your storage capacity if you're using a 9 x 9 array now. Who doesn't want to double their capacity?
