Abstract
The present invention refers to a device, comprising a hollow body having at least one open end and at least one barrier inside or at the end of the hollow body, which is non-permeable for liquids and solids under ambience conditions, however, becomes liquid-permeable by applying an external force like pressure, drag force or driving power to said barrier, the use of such a device for collection, storage, treatment or isolation of a biomolecule or biomolecules containing samples, a method for preparation of said device and a method for isolation or purification of any biomolecules using said device.
Claims18
A device, comprising (i) at least one hollow body, each hollow body having at least one open end;
- (ii) at least one barrier placed inside or at one end of the hollow body;
- (iii) at least two liquid-permeable elements inside the hollow body;
- and (iv) optionally at least one removable closing device to seal at least one open end;
- wherein the barrier is non-permeable for liquids and solids under ambience conditions, but becomes liquid-permeable by applying an external force to said barrier,
- the barrier is placed between the at least 2 liquid permeable elements and is in direct contact with at least one of said elements, and
- the liquid-permeable elements are selected independently from a frit, filter, fleece, and membrane, and are in contact with all of the inner side walls of the hollow body of the device and flush with said side walls.
