    摘要: A device and method is provided for the qualitative and semi-quantitative determination of the presence of phenothiazine-type drugs in urine. The article comprises an ion exchange resin which denotes cations in a reaction between a color forming reagent and the phenothiazine-type drug to produce a permanent color change. The intensity of the color change is proportional to the dose concentration.

    摘要: The specification and drawings disclose methods and apparatus for separating and/or isolating bacteria and tissue cells for testing or rapid automatic scanning. The invention uses an expansible membrane on which the tissue cell or bacteria sample is placed and thereafter expanded to cause the sample to be separated. Apparatus is disclosed for facilitating stretching of the membrane and automatically scanning it.
