A variety of flask sizes filled with phenol-red medium

T225 flask volume and surface area

Start your scale-up with a T225 flask that has the surface and ancillary options you're looking for in a tissue culture flask. Choose a cell culture flask from a collection that includes straight-neck or angled-neck options and surface treatment alternatives that help ensure your healthy tissue cells expand and grow in the flask of your choice.

Some useful numbers such as surface area and volumes of dissociation solutions are given below for T225 flasks.

Please note: The number of cells on a flask will vary with cell type. For this table, 6.3 x 106 HeLa cells were seeded and the confluent flask contained 30 x 106 cells.

Cell adhesion and growth on coated or modified glass or plastic surfaces

Growth substrates affect the adhesion, growth, morphology and differentiation of various cell types. However, the response to a given surface is cell type specific. Selection of a growth surface for cell culture should be based on cell culture performance and on application. In this technical bulletin, the growth of various cell types on plastic, soda lime glass and borosilicate coverglass was examined with surfaces that were either unmodified, coated with polylysine, or stably surface modified with non-biological reagents or electrical discharge.
