Abstract
The semi-rigid culture vessel is structured to transform a flexible culture vessel into a semi-rigid form to facilitate laboratory processes. The semi-rigid culture vessel includes at least two rims connected by at least one rib to form an internal support. The internal support is enclosed within the gas-permeable flexible culture vessel to form the semi-rigid culture vessel.
Claims17
A semi-rigid culture vessel comprising:
- at least first and second rims;
- at least one rib connecting the first rim with the second rim to form a non-collapsible semi-rigid internal support;
- and,
- a flexible culture vessel consisting of an integument having a membrane that is gas-permeable but impermeable to liquid and microorganisms, the integument consisting of a high density polyethylene material which is pliable and collapsible such that the polyethylene material can be stored and shipped in rolls, the polyethylene material being capable of sterilization in an autoclave;
- whereby the internal support is completely enclosed within the flexible culture vessel to form the semi-rigid culture vessel, the semi-rigid internal support being sufficiently structurally robust to enable the flexible culture vessel to be stored in an upright position.

A method of making a semi-rigid culture vessel, the method comprising the steps of:
- (a) providing a first rim;
- (b) providing a second rim parallel with the first rim;
- (c) providing at least one rib and connecting the first rim with the second rim to form a non-collapsible semi-rigid internal support;
- (d) depositing the internal support in a flexible culture vessel consisting of an integument having a membrane that is gas-permeable but impermeable to liquid and microorganisms, the integument consisting of a high density polyethylene material which is pliable and collapsible such that the polyethylene material can be stored and shipped in rolls, the polyethylene material being capable of sterilization in an autoclave, the semi-rigid internal support being sufficiently structurally robust to enable the flexible culture vessel to be stored in an upright position;
- and
- (e) closing the flexible culture vessel.
