摘要

An instrument for separation of liquid from solid material comprising: a volume filtration layer having a void volume of not less than 90% which is composed of fibrous material; and a pressure-resistant housing having a liquid entrance and a liquid exit which encases said volume filtration layer therein in such a manner that the side face of the volume filtration layer is tightly arranged in contact with an inner face of the housing so as to prevent passage of the solid material along the interface between the side face of the volume filtration layer and the inner face of the housing.
