Devices and methods for rapidly and incrementally or continuously, measuring rheological properties of polymers under different shear rates. The device includes a pump configured to accept a continuous stream of sample solution during an interval of time, an injector configured to inject a flow of the sample solution through two or more viscometers, and a computing and processing device configured to monitor and measure rheological properties of the solution under at least two shear rates simultaneously in the two or more viscometers.

The disclosure provides devices, systems and methods for the generation of encapsulated reagents and the partitioning of encapsulated reagents for use in subsequent analyses and/or processing, such as in the field of biological analyses and characterization.

The subject of the invention is a device for positioning an object in space, comprising at least 4 plates, each one able to move with respect to another of said plates which is contiguous with it along one of the 3 axes of space, it being possible for the movement of one plate with respect to another plate to be guided by a tenon/mortise assembly in which said tenon is secured to one of the plates and its mortise is produced in the other plate, the spatial orientation of each of the tenon/mortise assemblies being different from the other 2 and along one of the 3 axes of space.

A system, including method and apparatus, for generating droplets suitable for droplet-based assays. The disclosed systems may include either one-piece or multi-piece droplet generation components configured to form sample-containing droplets by merging aqueous, sample-containing fluid with a background emulsion fluid such as oil, to form an emulsion of sample-containing droplets suspended in the background fluid. In some cases, the disclosed systems may include channels or other suitable mechanisms configured to transport the sample-containing droplets to an outlet region, so that subsequent assay steps may be performed.

Disclosed herein are systems and methods for serial flow emulsion processes. Systems and methods as described herein result in reduced cross-contamination.

A testing method using a micro flow path device configured for a test liquid containing a specimen to be brought into contact with a drug therein and for a test on an action of the drug on the specimen includes: preparing the micro flow path device including: a plurality of micro flow paths, first and second openings which are disposed at both ends of each of the plurality of micro flow paths and communicate with an outside, a storage unit which is provided in each of the plurality of micro flow paths and stores the drug, and a gas-permeable membrane covering the first opening; applying a fluid pressure higher than an external pressure to the test liquid through the second opening from a syringe pump connected to the second opening to pressure-feed the test liquid to the storage unit; and observing a target region set in the micro flow path.

According to some embodiments, the present invention may include, or take the form of, a total organic carbon analyzer, featuring an injector, a reactor, condensation components and two three-way valves. The injector may be configured to provide a sample. The reactor may be configured to vaporize the sample received. The condensation components may be configured to condense and trap the sample vaporized by the reactor. The two three-way valves may be arranged between the reactor and the condensation components and configured to allow flow to either bypass or pass through the reactor and the condensation components, while in the bypass mode, the sample being injected at an appropriate rate so as to allow the sample to condense at or near the same rate as the sample is being injected.

A system and method for collecting produced fluid from a laboratory test chamber using a plurality of syringe pumps, wherein the pressure is selectively controlled during the collecting, and the pressure is selectively reduced prior to expelling the produced fluid to one or more collection flasks.
