Abstract

A tissue culture flask includes a base, a cover and a cap. The base has a bottom wall and a ramp extending up at an obtuse angle from the bottom wall to the front end of the flask. The flask also includes a sidewall enclosure that extends up from the bottom wall and the ramp. The sidewall enclosure includes a front wall at the end of the ramp furthest from the bottom wall. The front wall includes an opening, and a substantially tubular neck extends forward from the opening. The neck has a substantially circular cross-section at the front end. However, portions of the neck at the rear end have a substantially circular cross-section across the top of the neck and a substantially elliptical cross-section across the bottom of the neck. The elliptical sections of the neck are substantially tangent to the ramp at the front wall of the flask. The geometry facilitates access by pipettes, scrapers and other instruments.
