    摘要: A sample container for minimizing evaporation of a contained volume of sample includes a container housing, a repuncturable self-sealing membrane, and a collapsible sample bag. The container housing includes an open end and a hollow interior region. The repuncturable self-sealing membrane configured to self-seal after repeated punctures is engaged in the open end of the container housing and includes an exterior surface exposed to the external environment and an interior surface oriented toward the hollow interior region of the container housing. The collapsible sample bag includes a proximate end that is permanently attached to the interior surface of the repuncturable self-sealing membrane.

    摘要: A micromachined device such as a solid-state liquid chemical sensor for receiving and retaining a plurality of separate liquid droplets at desired sites, a method of making the device and a method of using the device are provided. The technique works for both aqueous and solvent-based solutions. The device includes a substrate having an upper surface, and a first set of three-dimensional, thin film well rings patterned at the upper surface of the substrate. Each of the wells is capable of receiving and retaining a known quantity of liquid at one of the desired sites through surface tension. A method for patterning a membrane/solvent solution results in reproducibly-sized, uniformly-thick membranes. The patterning precision of this method allows one to place the membranes closer together, making the sensors smaller and less expensive, and the uniform film thickness imparts reproducibility to the sensors.

    摘要: A container for holding a biologic fluid sample for analysis is provided which includes a chamber and a label. The chamber includes a first wall, a transparent second wall, and at least one feature located at a known spatial location within the chamber. The transparent second wall permits a fluid sample quiescently residing within the chamber to be imaged through the second wall. The at least one feature is operable to enable the analysis of the biologic fluid. The label directly or indirectly contains information regarding the features and the spatial location of the features within the chamber. The sample is analyzed by an analytical device that utilizes the information communicated through the label.

    摘要: Devices and methods are disclosed for synthesizing compounds on the surface of supports. The devices are flow devices, which include a housing comprising a housing chamber. The housing has an opening adapted for insertion of a support into the housing chamber. A sealing member is movably mounted in the housing chamber and adapted to engage the support to form a reagent chamber between a surface of the support and a surface of the sealing member. A mechanism is included for moving the sealing member within the housing chamber. The device has both an inlet and an outlet, which are both in fluid communication with the reagent chamber. In the methods of the invention a support is placed into a chamber of a device such as described above. The mechanism adapted to engage the support on a surface opposite the surface engaged by the sealing member is activated to urge the support toward the sealing member. The pressure-activated mechanism is activated to urge the support against the aforesaid mechanism and against an interior wall of the housing chamber to form the reagent chamber. A fluid reagent for conducting the reaction step is introduced into the reagent chamber by means of the inlet. Thereafter, the fluid reagent is removed from the reagent chamber. The pressure-activated mechanism is deactivated and the support is removed from the housing chamber. In this way the reagent chamber is formed and un-formed in situ.

    摘要: An adapter for holding a sample container includes a main body portion and a tapered body portion that forms a continuation of the main body portion. The tapered body portion includes a mouth opening that is of lesser diameter than the diameter of the main body portion. The mouth opening of the adapter is sized to provide direct support of a sample container which holds a liquid sample. During liquid level sensing ultrasonic waves from an ultrasound detector are reflected back to the sound detector as echoes from the lip flange of the sample container and from the liquid level within the sample container. The tapered surface of the adapter deflects sound echoes away from the sound detector. The adapter is thus invisible to the ultrasound detector. The echo from the liquid level is a variable duration echo and the echo from the lip flange of the sample container is a fixed duration echo that is always of lesser duration than the variable duration echo. Thus the sound detector can easily recognize the liquid level echo and convert the characteristics of the liquid level echo to a discernible liquid level.
