Abstract: ABSTRACT      Disclosed is an improved apparatus for conducting immunoassays.  The apparatus comprises a container, and a test zone to which is bound an antibody, typically a monoclonal antibody, or which is capable of extracting cells from a fluid sample.  The test zone may be membrane, filter or a porous matrix in which microspheres, to which are bound antibody, are entrapped The apparatus further comprises a liquid absorbing zone which is composed of adsorbent material which acts, when in contact with the test zone, to induce flow through the test zone when a fluid sample is added to it.  At least one vent port in communication with the liquid absorbing zone and the opening of the container is provided to allow gas displaced by the addition of fluid to be discharged from the container.  The flow of the displaced gas in a direction opposite to the flow of assay reagents through the liquid absorbing zone.          Accordingly, the container can be sealed entirely from the environment by the use of a single removable seal over the opening of the container.

Abstract: ABSTRACT OF THE INVENTION          The present invention relates to a method of monitoring the quantity of extract from mash in a brewing process.  A mash, typically made up of ground malt and water is introduced in a lauter tun having, typically, a first, central core zone, a second zone surrounding the first zone and a third zone surrounding the second zone, around the periphery of the lauter tun, there being extraction pipes for extracting wort from each of the zones in said lauter tun.  Saccharified wort is extracted from the lauter tun, via the extraction pipes from the zones, the pipes leading to a wort kettle, and sparge water is added to the lauter tun as wort is extracted to extract further solids from the ground malt in the mash.  The extractable solids in the extraction pipe from each said zone are monitored by sequentially passing samples of wort from each pipe through a densimeter.  Then, the flow of wort from the extraction pipe from each said zone is adjusted by automatic flow adjustment means to obtain a flow of wort in each extraction pipe having approximately the same extractable solids.
