The present invention provides microfabricated substrates and methods of conducting reactions within these substrates. The reactions occur in plugs transported in the flow of a carrier-fluid.

A device for synthesizing a radiotracer includes a microfluidic chip having a concentration module configured to concentrate and capture a radioactive reagent from a radioactive regent mixture, a reaction chamber in fluidic communication with the concentration module and configured to synthesize a radiotracer by reaction of the concentrated radioactive reagent and a radiotracer precursor therein, and a purification module in fluidic communication with the reactor chamber and configured to purify the synthesized radiotracer. The device also includes a heating means positioned in relation to the microfluidic chip for heating the microfluidic chip during evaporation and reaction; and a first valve fluidically coupled with the concentration module and the reaction chamber and a second valve fluidically coupled with the reaction chamber and the purification module for operably controlling transit of various substances or mixtures among the concentration module, the reaction chamber and the purification module.

Parallel uses of microfluidic methods and devices for focusing and/or forming discontinuous sections of similar or dissimilar size in a fluid are described. In some aspects, the present invention relates generally to flow-focusing-type technology, and also to microfluidics, and more particularly parallel use of microfluidic systems arranged to control a dispersed phase within a dispersant, and the size, and size distribution, of a dispersed phase in a multi-phase fluid system, and systems for delivery of fluid components to multiple such devices.

A dispenser for dispensing absorbent product having an outer cover having a first cover portion, a second cover portion and an interior region configured to hold the absorbent product and at least partially defined by one or more of the first and second cover portions, wherein the first cover portion is removably engaged to at least a portion of the second cover portion along a cover joint; and wherein the outer cover includes a hydrophobic section proximate the cover joint to direct any liquid on the cover near the cover joint away from the cover joint.

The invention relates to a fluidic purifying device designed to clean a fluid of at least one pollutant, comprising a fluidic purification network, characterized in that the fluidic purification network comprises a plurality of microfluidic channels, each microfluidic channel being defined by one or more fluidttight walls, each microfluidic channel comprising at least one zone on the interior surface of said microfluidic channel that exhibits at least one autonomous purifying agent and each microfluidic channel exhibiting, in such a zone, a height less than 60 m in a direction normal to the main direction of flow of the fluid, the purifying agent or agents, and the sizing of said zones, being configured in such a way as to allow at least 10% of the pollutants to be captured and/or broken down by said zones, for at least one flow rate of the fluid that is to be purified.
