A small volume laboratory filter having a thin rectangular body and coaxial inlet and outlet sleeves connected to opposite ends thereof. A very thin filter cavity is formed in the body and lies in a plane inclined slightly to the common axis of the inlet and outlet sleeves. The cavity is divided by a filter membrane into extremely thin chambers, one communicating with the inlet sleeve and the other with the outlet sleeve. A rigid package for the filter is sealed across one end by a flexible cover which when stripped from the package exposes the inlet sleeve so that it may be readily engaged by a syringe nipple or other fluid source without the user having to touch the filter. When the inlet sleeve is engaged, the filter may be withdrawn from the package.

A small volume laboratory filter comprising a thin rectangular body having opposed ends and connecting sides and opposite generally parallel faces, means defining a shallow filter cavity extending over a major portion of the body\s rectangular dimensions and having opposite side walls, said cavity being inclined with one end lying closely adjacent one face of the rectangular body along one end thereof and the opposite end of the cavity lying closely adjacent the other face of the body along the opposite end thereof, an inlet sleeve connected to one end of the body and an outlet sleeve coaxial therewith connected to the other end thereof, separate inlet and outlet manifolds connecting each sleeve to the cavity adjacent the respective ends, the respective connections to the cavity being through the opposite side walls, and a filter membrane bisecting the cavity and disposed parallel to the cavity side walls so that the manifold connections to the cavity from the inlet and outlet sleeves are disposed on opposite sides of the membrane.
