Cryopreservation - Mr. Frosty (Jun/01/2010 )


Can sme1 let me know an alternate to Mr. Frosty. I want to use some other inhouse material as an alternative. Is there some way? Plz let me know!

-Born free-

We use those foam racks your 15ml centrifuge tubes come in. Put the cryovials in and then turn another rack upside down on top to sandwich them in. -80 overnight (or over the weekend!) and then into LN2 the next day.
Never had a problem with it.

And a lab mate of mine uses those plastic eppie racks, with no problems either.

Hope that helps.
