An apparatus and method for hydrating a particulate biomaterial with a liquid biomaterial includes a vacuum device and a valve for withdrawing a gas from the particulate biomaterial and introducing the liquid biomaterial. The valve includes a hub, a valve body, a particulate port, a vacuum port, and a liquid port. The valve body selectively moves between first and second positions. The valve body at least partially defines a first passage and a second passage. The particulate port, the vacuum port, and the liquid port are each configured to fluidly connect to a particulate container, the vacuum device, and the liquid container, respectively. In the first position, the first passage fluidly connects the vacuum port to the particulate port for withdrawing the gas from the particulate container. In the second position, the second passage fluidly connects the liquid port to the particulate port for hydrating the particulate biomaterial.
