The device includes a housing, a chamber, and a withdrawal port. The chamber is rotatably mounted within the housing. The chamber includes a chamber base and a sidewall. The side wall extends from the chamber base. At least a portion of the sidewall is defined by a filter that permits passage of a first component of the multi-component composition out of the chamber through the filter and to the housing base. The filter restricts passage of a second component of the multi-component composition through the filter. The withdrawal port extends from a position proximate to the housing base to an exterior of the device. The withdrawal port permits the withdrawal of the first component from the housing base to an exterior of the device. ## Claims ### Claim 1 A device for isolating a component of a multi-component composition comprising: a housing having a housing base;
