    摘要: A microtiter plate for blood typing consisting of a flat-bottomed plate of rigid transparent polystyrene having a plurality of wells, the polystyrene being surface treated by a corona and/or plasma method of applying high power electric energy at high frequency resulting in a permanently measurable negative ion-charge at the surface of the wells, and layers of substantially pure antiserums dried on the wells without any binder from a suspension or solution of the antiserums and tightly but releasably bound to the polystryene.

    摘要: In a device for testing air for microorganism content with a rapidly rotating impeller inside a cylinder that has a backing sheet coated with culture medium against its inside surface, microorganisms that vary more extensively in size can be detected with almost equal effectiveness, the throughput of air can easily be determined, and the precipitation effect can be precisely tested because the backing sheet rotates along with the impeller, the blades of the propeller are at a low angle to the plane it rotates in, the air enters at a location that is separate from the location at which it leaves, through inlets from above and down and out through outlets, and the inner surface of the rotor below the impeller chamber is in the form of a channeling cylinder.
