Abstract
The present disclosure provides methods for stabilizing a colloidal dispersion during transport for low defect tolerance applications. The methods involve eliminating fluid interfaces within a dispersion, storing the dispersion in an environment of inert gas, and degassing the dispersion. Several bottle closure devices are described which may be ideal for use with these methods, being able to seal a container filled with a dispersion, permit the removal of headspace and rapidly empty the contained dispersion. In one aspect, the device includes a vented cap and semi-permeable membrane, which allows the passage of gas into and out of the container, and a dispenser nozzle integrated with the device to allow a stored dispersion to be dispensed without removing the device from the container. In another aspect, the bottle closure device includes an attachment point for a removable downtube and dispenser nozzle.
