GenClone Cell and Tissue Culture Flasks are offered in 12.5, 25, 75, 182 cm2 sizes and are available tissue culture treated or non-treated. Distortion free, completely flat growth surfaces provide even and consistent cell growth for optimal proliferation of cells. Flasks are graduated with a frosted writing area and feature a wide, angled neck design that offers 100% access for washing and retrieving cells. All flasks are available with your choice of vented or plug seal caps. Vented caps feature a 0.22μm hydrophobic membrane filter that allows gas exchange and excludes bacterial and fungal contaminates. Plug seal caps provide an air tight seal or allow gas exchange with a one quarter turn of the cap. The pronounced rim allows for easy stacking and molded spacers on the base create venting gaps that allow heat and gas exchange between stacked units to speed up acclimation to 37oC. All flasks are sterilized by gamma irradiation and certified RNase, DNase and Pyrogen Free.
