Abstract:
A combinatorial chemistry reactor system for the parallel processing of reaction mixtures. The system comprises a frame, a head mounted in fixed position on the frame, and a reactor block having a plurality of wells therein for containing reaction mixtures. The reactor block is movable with respect to the head between a first position in which the reactor block and head are assembled for conducting reactions in the wells and a second position in which the reactor block is removed from the head for providing access to the vessels. Gaps in the reactor block between the wells serve to thermally isolate the wells from one another. Other features relating to pressure relief, reactor block temperature control, and sensor mounting are also disclosed.
Abstract:
Device consisting of a support (1) and at least two seals (2), which are arranged in a row and are hermetically fitted into cavities, and protrude from the support laterally with respect to inlet and outlet openings, one end of the support being provided with an inlet opening (3) and one end being provided with an outlet opening (4), and the seals being provided with a least one inlet opening and one outlet opening, and the support containing at least one first channel (5) which starts at the inlet opening (3) and is continuous, and is arranged in such a way that it opens into the inlet openings in the side walls of the seals arranged in a row, and one second channel (6) which starts at the outlet opening and is continuous, and is arranged in such a way that it opens into the outlet openings in the side walls of the seals arranged in a row. The system is suitable for simultaneous multiple studies, in particular with the use of microtitration plates, and physical measurements of the results directly in the containers, for example of a microtitration plate. The multiple studies may be used to perform screening processes to discover and develop polymorphic and pseudopolymorphic forms, new formulations and suitable crystallisation conditions.
Abstract:
The system comprises a flow through reaction vessel having an inlet, an outlet and a reaction zone intermediate said inlet and outlet. The system further comprises reagent feed means for introducing one or more reagents into said vessel, said one or more reagents forming one or more reaction products in said reaction zone. Said reagent feed means at least include a liquid feed means for introducing a liquid into said inlet of said vessel. The vessel has a liquid evaporation zone intermediate said inlet and said reaction zone. Said liquid evaporation zone comprises an evaporation structure contacting said liquid and providing a liquid residence time in said liquid evaporation zone improving evaporation of said liquid.
Abstract:
A high capacity microarrayer for spotting solution onto slides (4A1-4E10) in an automated microarray dispensing device. A microp late indexing device automatically moves, in sequence, a plurality of microplates (5) to a solution removal area. A dispense head(6) accesses each microplate at the solution removal area to remove solution from the microplate. The dispense head than moves to a slide positioning station to spot slides at the slide positioning station. In a preferred embodiment of the present invention, the microplate indexing station has at least one input stacking chamber for stacking microplates, and at least one output stacking chamber for stacking microplates. A beam walking beam indexer is for moving microplates from the input stacking chamber to the output stacking chamber.
Abstract:
The invention relates to the use of protein design automation (PDA ) to generate computationally prescreened secondary libraries of proteins, and to methods and compositions utilizing the libraries.
Abstract:
The invention relates to a method for producing a carrier for conducting a biochemical analysis. To this end, a carrier is produced with a large number of pits that are arranged along a spiral. Copies are produced starting from a master carrier and they contain subsets of the pits of said master carrier. When producing the copies, the pits of the master carrier are read, and the tracking of the laser is corrected according to the arrangement of the pits of the master carrier.
Abstract:
An optical biodisc has a substrate, a first reflective layer over the substrate, an opening in the first reflective layer for receiving an investigational feature, and a second reflective layer over the opening for reflecting light transmitted through the substrate.
Abstract:
A method for ex situ production of at least one biochip consisting in projecting a microvolume of a reagent on a substrate (18), said reagent comprising at least one probe diluted in an appropriate solvent in order to form, after elimination of said solvent, a contact element (20) comprising said probe, characterized in that said method consists in using a microprojection device (D) comprising at least one reservoir (1) wherein the reagent (3) is stored and at least one pressurized gas source (5) communicating with the reservoir (1), in addition to projecting the microvolume of reagent through an ejection nozzle (14) under the effect of pressure exerted by the gas on the reagent.
Abstract:
The present invention relates to the field of fluid dynamics. More specifically, this invention relates to methods and apparatus for conducting densely packed, independent chemical reactions in parallel in a substantially two-dimensional array. Accordingly, this invention also focuses on the use of this array for applications such as DNA sequencing, most preferably pyrosequencing, and DNA amplification.
