    摘要: A carrier having at least one kinetics and fluorescence enhancing support and a dry substance selected from the group consisting of fluorogenic substrates, B methylumbelliferone, 7-amino-4-methyl coumarin, B-napthylamine, fluoroscein, and resorufin deposited on the support demonstrates substantial enhancement of hydrolysis kinetics and fluorescence over pure liquid systems. When the device has a plurality of supports and the supports have different fluorogenic substrates an enzyme rate-of-reaction profile representative of a microorganism in the suspension can be determined and used to identify the organism. The device can also be used to characterize enzymes expressed by other biological specimens.

    摘要: An apparatus and method for the detection of the growth of microorganisms through infrared analysis of a sample of the gas produced by growth of the microorganism is descirbed. In the method, a sample of the headspace gas in a vial containing a growth medium which has been inoculated with a sample suspected of containing a microorganism is removed and transferred to a sample cell where infrared analysis is used to determine the presence of carbon dioxide, if any, produced by the growth of the microorganism.

    摘要: The present invention relates to a method and apparatus for transferring fluid from a blood collection tube to a glass capillary tube. This eliminates the need for health care workers to open the blood collection tube, insert a glass capillary tube into the blood collection robe, pipet a fluid such as blood into the tube and be exposed to the excess fluid from the capillary tube. The apparatus of the present invention is directed to a transfer device, and a dispenser which can be used with the transfer device, for carrying out this method.

    摘要: A method and apparatus for detecting the presence of biological activity in a sample of material. In the method, a sample of the material is placed in a closed container with a growth medium which includes a carbon source which may be metabolized to produce carbon dioxide. The medium with the sample therein is exposed to conditions conducive to the occurrence of normal metabolic process for a period of time sufficient to cause production of CO.sub.2 by the metabolism of the carbon source. Thereafter, the presence of CO.sub.2 in the gaseous atmosphere above the medium is detected by measuring the infrared absorbance of the gaseous atmosphere with the container by passing an infrared beam through the container and the gaseous atmosphere and detecting the infrared absorbance of the gaseous atmosphere.
