Mr. Frosty Freezing Container
5100-0001
This is an 18-slot cryovial freezing container. I typically use 2-ml cryovials for freezing my cell lines. I place cryovials in this container (filled with fresh isopropanol) and store it at -80 deg C freezer overnight. I then transfer cryovials to liquid nitrogen freezer. I have been using Mr. Frosty for more than a decade and I highly recommend it.
