OriGen PermaLife Cell Culture Bag

The OriGen PermaLife cell culture bags represent the optimal way to harvest, expand, concentrate, and freeze critical cell cultures.
Made of FEP, the PermaLife bag contains no plasticizers or chemical residuals which can leach into and alter delicate cell cultures. Because FEP is inert, antibodies, cytokines, and other genetic material are unaffected by the PermaLife bag.
Swab-able, needle-free valves are provided on every PermaLife bag to preserve sterile access. PermaLife FEP bags are a closed system, so the possibility of contamination is greatly reduced.
The PermaLife bag has an optical transmission of greater than 95%, and observation of the cultures under a microscope is possible without risking contamination of the culture.
PermaLife bags are gas-permeable and provide a high rate of oxygen transfer to cells under culture. Additionally, water permeability is very low, so water loss is negligible and humidified incubators are not required.
