Abstract
A system for aerating a marker material. The system includes a first container, a second container, and an aeration connector. The aeration connector includes a body and a screen disk disposed within the body. The first container is in communication with the second container via the aeration connector. The screen disk of the aeration connector is configured to aerate a marker material as the marker material is repeatedly passed between the first container and the second container.
Claims6
A method of manufacturing an aerated hydrogel comprising:
- inserting hydrogel material in a first container;
- inserting aerating fluid in a second container;
- coupling the first and second containers together through a lumen of a coupler;
- and
- transferring the inserted hydrogel and the inserted aerating fluid back and forth between the first and second containers through a filter positioned in a fluid communication path between the first and second containers and having a plurality of openings with each opening having a smaller area than the lumen of the coupler such that each opening is configured to introduce turbulence in the hydrogel or the aerating fluid.
