Abstract (en)
[origin: WO8806723A1] A disposable biochemical test apparatus for use in filter assays and static assays. A preferred form of the apparatus is substantially rectangular, comprising an upper surface (13), trapezoidal side support walls (15) providing stability, a bottom surface (11), and end plates (16, 17) at each end. The upper surface (13) forms a planar template containing six tapered cylindrical apertures or wells (12) arranged linearly and extending through the template. Underlying the template is a microporous membrane (14) bonded to the lower surface of the template. One of the end plates (17) has an exit port (19) which provides an exit for fluids from the enclosed region. The bottom surface (11) forms an exit ramp (18) slanting upward from the exit port (19) to the other end plate (16). The apparatus is provided as a single unit which may be disposed of after use. In use a syringe aspirates fluid by providing gentle vacuum through the exit port (19).
