Abstract
A fluid collection device for collecting and separating a liquid into its phases is provided which includes a collection container and an elongate housing having gel-like sealant therein. The sealant has a specific gravity between those of the separated low and high density phases. The housing has a sealant flow control valve in the low density phase portion of the container which is opened in response to a decrease in the specific gravity of the liquid adjacent the valve.
