This 2800 mL wide mouth PYREX® Fernbach-style culture flask is designed for culturing organisms requiring a large surface area to volume ratio. It can also be used in serum production. This flask has a heavy beaded rim to protect against chipping and include a large marking spot.Note: Do not use this flask on a heat source smaller than the base of the flask. Uneven heating of the flask could cause breakage.

This 2800 mL wide mouth PYREX® Fernbach-style culture flask is designed for culturing organisms requiring a large surface area to volume ratio. It can also be used in serum production. Triple baffled on the bottom outside edges to achieve maximal oxygen transfer to culture medium. Beaded neck rim is approximately 60mm I.D. and accepts cotton plugs or No. 13 rubber stoppers. This flask has a large marking spot.Note: Do not use…

These 125 mL PYREX® long neck shaker culture flasks are basically Erlenmeyer flasks to which a long straight, rimless neck of heavy tubing has been added. The longer necks reduce the amount of splashed solution reaching the closure. They are ideal for shaker cultures. Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance. For convenience, these flasks include a markin…
