Devices, systems, and methods for the precise dispensation of small volumes of liquids are presented. A fluid microdispenser comprises a liquid-filled tube, an actuator coupled to the tube, and a tip at one end of the tube. When the actuator applies an actuation pressure, a precise volume of liquid is ejected from the orifice of the tip. The orifice is manufactured to control the volume of liquid ejected by each actuation and, therefore, may have a diameter smaller than that of the liquid-filled tube. The invention comprises systems, methods, and devices so that the inner diameter of the liquid-filled tube is decreased (tapered) to that of the orifice so as to maximize transmission to the orifice of the pressure generated by the actuation stimulus. This enables the volume of liquid ejected by each stimulus to be reproducibly controlled by the amplitude of the actuation stimulus.

A high throughput chemical screening method uses methods of concurrent transport and/or processing to increase throughput. A screener may concurrently retrieve chemicals from an addressable chemical storage module and deliver chemicals to a liquid handling module. The screener may also use one transport lane for moving chemicals away from a storage module, and a second transport lane for moving chemicals toward the storage module.

The present invention relates to multi-well platforms, lids, caddies and any combination thereof The multi-well platforms comprise a plurality of wells that can be of any shape and can be arranged in any ornamental pattern. The lid comprises an area corresponding to the well field. The caddy has a footprint approximately that of a standard 96-well microtiter plate. When the multi-well platform is engaged with the caddy, the wells of the well-field of the multi-well platform are preferably not obscured by the caddy when viewed from the bottom of the combination.

摘要:
The present invention makes use of a single detector to monitor several process functions, e.g. reaction efficiency, reagent flow rates, the presence of empty reagent reservoirs, the absence of a chemical reactor column in the system, blockage of flow system, etc., at a single location in the flow system. In accordance with the detection scheme of the present invention, only one detector is required to accomplish the same, if not more, functions as many detectors in the prior art instruments. In the described embodiment, an optical detector is positioned downstream of a chemical reaction chamber. This detector monitors the effluent from the reaction chamber to monitor the reaction efficiency. It also monitors the system functions upstream of the reaction chamber. System flow rate is monitored by detecting the presence of a gas bubble which has been introduced into the system at a known instance. Depletion of reagents in the reservoirs can be detected by monitoring the absence of the reagents at the detector at times when the reagents are expected. The flow system may be periodically diagnosed to check for flow blockage or missing flow component, by monitoring the flow past the detector which corresponds to a predetermined succession of reagents introduced into the system. Any deviation from a predictable succession of changes in the flow monitored by the detector indicates possible blockage of the flow delivery system or missing flow components.
