摘要:
An assay device and method of use thereof includes a sample tray comprising a plurality of sample wells having a first volume, and a slide tray comprising a slide, and a liquid dispenser. The slide comprises a plurality of reaction sites on a bottom surface of the slide. The liquid dispenser is configured to dispense a plurality of liquid samples into the sample wells. The sample wells are configured to hold the liquid samples. Each of the liquid samples has a second volume such that the second volume exceeds the first volume and each of the liquid sample sits within and above one of the sample wells. The slide tray and the sample tray are configured such that the slide tray can be placed onto the sample tray, at least one of the reaction sites can be positioned directly above at least one of the sample wells containing a liquid sample, and the liquid sample can be drawn onto the reaction site upon the liquid sample contacting the bottom surface of the slide.

Semi-automated or automated manufacturing of micro- or nanostructured identification features on objects and compositions, and especially pharmaceutical compositions. In particular, a motorized stamping apparatus capable of precise hot embossing with or without closed-loop control of the loading; a modular stamp head for a high-throughput parallel stamping apparatus that comprise an array of compact, error-tolerant, individually temperature-controllable stamping elements; inexpensive stamp holders for said elements, as well as associated methods. The inventive features do not reside in the method of making the stamps.

摘要:
A system for positioning equipment quickly and accurately over a plurality of desired positions by employing a "long move" mode of operation and a "short move" mode of operation to adapt the operation of the positioning system to variable and changing conditions. The system generally includes a microprocessor as the controlling means, a controlled valving means, a pressure source coupled to the valving means, an encoder sensing means and a positioning means defined by a pneumatic cylinder.
