Abstract
There is provided a method for preparing a dense hydrogel comprising an at least partially gelled hydrogel, placing the at least partially gelled hydrogel in fluid communication with an end of a capillary, and driving the at least partially gelled hydrogel into the capillary to form a dense hydrogel. There is also provided a system for preparing the dense hydrogel comprising a capillary having a bore; and a driver in communication with an end of the capillary for driving an at least partially gelled hydrogel into the bore of the capillary to form a dense hydrogel.

A system for preparing a dense hydrogel, the system comprising:
- a capillary having a first open end, a second open end and a bore defined therebetween;
- a driver in communication with the second open end of the capillary, the driver arranged to selectively exert:
- a negative pressure to drive a hydrogel into the capillary to form a dense hydrogel in the capillary, and
- a positive pressure to drive the dense hydrogel out of the capillary.
A system for preparing a dense hydrogel, the system comprising:
- a capillary with a first open end, a second open end and a bore defined therebetween;
- a driver in communication with the second open end of the capillary, the driver arranged to exert a pressure differential to drive a hydrogel into the capillary to form a dense hydrogel in the capillary, the hydrogel comprising a solid component and a liquid component, wherein the system is arranged to allow removal of at least a portion of the liquid component to form the dense hydrogel in the capillary.
A kit for preparing a dense hydrogel, the kit comprising the system of claim 1, and the hydrogel in a support.
