Petaka is virtually vapor hermetic so does not require a humidity saturated incubator.
You may store pre-filled Petakas, ready to host cells, and have them prepared for immediate use. Refrigerated storage time is not limited by dehydration. Elimination of saturated humidity in the incubator, water pan, and mist, reduces the risk of cross contamination in the incubator.
In Petaka, an integrated micro-channel system (MFS) protects the internal environment, avoiding unwanted water evaporation. Dehydration at 37ºC has been minimized, allowing culture incubation for 30 days at RH 10% with a final media dehydration below 10%.
