These polypropylene racks hold 25 cc, 75 cc (50 to 75 ml or 250 to 260 ml) or similar sized tissue culture flasks in a vertical position.

• Rectangular holes in the top and center plates stabilize the flasks preventing tipping
• Handles on each end of the rack allow for safe transport of flasks to the incubator
• Steam autoclavable at 121 ºC (250 ºF)

Flasks can be easily organized to improve processing and to avoid errors in collecting used media, media change, washing of cell monolayer, trypsinization and seeding of cells.
