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.

A bead dispensing system is provided for delivering small amounts of substances onto substrates. The system can include, for example, a movable support structure having an array of spaced-apart projections depending from its lower side. An attraction source, such as a vacuum, magnetic, and/or electrostatic force, is operable at each projection end region to attract and retain one bead. The projection array can be aligned with an array of bead-receiving regions of a substrate, e.g., an array of spaced-apart wells of a micro-plate or card. In one embodiment, a plurality of reagent-carrying beads are picked up, retained at respective projection end regions, and moved to a location over a multi-well plate. The beads are then released in a fashion permitting each bead to land in a respective well. The system of the invention is particularly useful for fabricating arrays of reagents.

The invention provides methods, apparatus, and systems for performing high-throughput preparation and screening of salts and polymporphs of drug candidates. The invention is directed towards enhancing the pre-formulation discovery process used for drug development. In particular, processes that determine suitable salts and processes that discover substantially every polymorph that can form from a particular drug candidate are provided. The processes are performed using several apparatuses that are specifically configured to carry-out various steps in a high-throughput characterization process. One such apparatus is configured for synthesizing a plurality of library members based on, for example, a library model generated by a computer system.

The invention relates to a system that feeds gaseous or liquid media into moveable sample vessels or reaction vessels in vacuum centrifuges or reaction chambers that are provided with an integrated shaker. An adapter plate (6) fitted with needles (7) that are allocated to individual vessels is arranged inside the centrifuge or reaction chamber above the sample vessels (5). The adapter plate is provided with a system (9) for the introduction of the gaseous or liquid medium. The height of the adapter plate can be adjusted. This enables the depth at which the needles are introduced into the sample vessels to be chosen at will.

The invention relates to a device that comprises a tool holder (1) that can be adjusted in an x axis, an y axis which is perpendicular thereto, and a z axis that is perpendicular both to the x axis and the y axis and that can be pivoted about the z axis. A dispense head (350) for solid material is mounted on the tool holder (1) as the tool. Two scales (369, 374) are disposed on the dispense head (350) for solid material, said scales weighing the material which is or is to be delivered by the dispense head (350) for solid material. The inventive design with two scales directly mounted on the dispense head (350) for solid material allows for weighing of the material without the dispense head (350) for solid material or the material having to be placed on separate scales.
摘要:
An apparatus and method for carrying out and monitoring the progress and properties of multiple reactions is disclosed. The method and apparatus are especially useful for synthesizing, screening, and characterizing combinatorial libraries, but also offer significant advantages over conventional experimental reactors as well. The apparatus generally includes multiple vessels for containing reaction mixtures, and systems for controlling the stirring rate and temperature of individual reaction mixtures or groups of reaction mixtures. In addition, the apparatus may include provisions for independently controlling pressure in each vessel, and a system for injecting liquids into the vessels at a pressure different than ambient pressure. In situ monitoring of individual reaction mixtures provides feedback for process controllers, and also provides data for determining reaction rates, product yields, and various properties of the reaction products, including viscosity and molecular weight.
