Abstract
The invention relates to a cell culture insert (1) comprising a beaker-shaped insert wall (11), a base (9) consisting of a membrane filter, projecting support arms (3, 4) that are distributed around the periphery of the top and lateral spacers (7, 8) for a vertical and horizontal orientation in a well (2) containing a liquid culture medium (N) in a cell culture plate. According to the invention, the spacers (7, 8) are distributed around the periphery of the cell culture insert (1) and have different radial lengths in such a way that a large feed opening (5) and several smaller openings (5A) are formed.
Claims16
A cell culture insert (1) comprising a beaker-shaped insert wall (11) having a membrane filter bottom (9), a top, and projecting support arms (3, 4) that are distributed around the circumference of the top and having lateral spacers (7, 8) for a vertical and horizontal orientation in a well (2) with a liquid culture medium (N) in a cell culture plate, characterized in that
- the spacers (7, 8) are distributed around the circumference of the cell culture insert (1) and have different lengths to the insert wall (11) including a shortest spacer (8), in such a way that one large feed window (5) and multiple smaller windows (5A) are created when the insert (1) is in rest position in the well (2);
- wherein the shortest spacer (8) has a knob shape.
A cell culture insert (1) comprising a beaker-shaped insert wall (11) having a top, a membrane filter bottom (9) and projecting support arms(3, 4) distributed around the circumference of the top of the insert, and having lateral spacers (7, 8) for vertical and horizontal orientation of the cell culture insert (1) in a well (2) containing a liquid culture medium (N) in a cell culture plate, wherein lateral spacer (8) is knob shaped;
- wherein at least one of said projecting support arms (3, 4) is shorter than at least one other (4) of said projecting support arms (3, 4), whereby the cell culture insert (1) in rest position is eccentrically suspended in the well (2) by the support arms (3, 4) so that one large feed window (5) and a plurality of smaller windows (5A) are created.
