IsoFreeze reversible racks with lid

Manufactured from virtually unbreakable polycarbonate and filled with a non-toxic gel,
those Isofreeze temperature maintenance racks provide consistent thermal protection for
PCR reagents, cells, enzymes or other temperature sensitive agents when removed from
the freezer or refrigerator for extended periods of time, and provide safe storage on the
event of freezer failure.
Each rack can accommodate up to 20 1.5/2.0 ml microtubes on one side, or 20 0.5 ml
microtubes on the reverse side.
Racks feature a transparent lid for better sample viewing. Each well in the rack is numbered.

Model M-570 (white) will maintain a temperature of 0 ºC on the bench top for 5 hours.
Model M-571 (blue) will maintain a temperature between –10 ºC and –20 ºC on the bench top up to 3 hours.
