摘要:
The present invention relates to a continuous process for conducting a chemical reaction in a liquid reaction medium. Characteristically: - said continuous process is carried out in a microreactor (10), - said chemical reaction produces a solid insoluble in said liquid reaction medium, and - said continuous process comprises the continuous extraction of said solid, as it is produced, with a solvent S2, immiscible with said reaction medium.
Such a process is advantageously carried out for conducting the activation of a carboxylic acid in the presence of an organic base.

The invention relates to a device for separation of substance mixtures on the micro scale. The invention further relates to a process for separating substance mixtures using the inventive device. The device is a device for separating substance mixtures and for performing chemical reactions between immiscible fluid media on the micro scale, comprising a first channel plate with at least one first process channel for a first fluid medium, an inlet and an outlet, and a connecting or distributing channel in each case, which connects the inlet to the first process channel, and a further connecting or distributing channel which connects the first process channel to the outlet, a second channel plate with at least one second process channel for a second fluid medium immiscible with the first, an inlet and an outlet, and a connecting or distributing channel in each case, which connects the inlet to the second process channel, and a further connecting or distributing channel which connects the second process channel to the outlet, and a microscreen as a separating means between the two process channel, wherein the microscreen has a multitude of orifices which have an aspect ratio of 1.5 to 10.

A microfabricated reaction chamber system for carrying out a nucleic acid sequence amplification and detection process on a nucleic acid sample, the process comprising at least first and second process steps using first and second reagents, the device comprising: an inlet port; a first reaction chamber in communication with the inlet port, for carrying out the first process step; a second reaction chamber in communication with the first reaction chamber, for carrying out the second process step; and an outlet port in communication with the second reaction chamber.
摘要:
The invention providing methods of loading and unloading particulate from microchannels in apparatus that contains multiple microchannels, typically apparatus that is designed to operate with hundreds or thousands of particulate-containing microchannels. Aligning a sonicating head at one end of a set of microchannels provides a particularly effective mode for densifying particulate in microchannels. The particles may also be loaded using fluidization cycles or a sliding door.
