Abstract:
The invention is a device for processing materials comprising a mixing chamber having a valve for removal of the material from the mixing chamber and a piston which fits within the mixing chamber in a manner such that the piston can be moved to remove substantially all material from the mixing chamber via the valve; at least one, preferably at least two, retractable mixing element(s) wherein each of such elements is movable in and out of the mixing chamber through a port wherein the element and port are configured such that during mixing and when the element is withdrawn from the mixing chamber substantially no material is removed from the mixing chamber via the port. The invention is also a method of using such a device and a system comprising use of such devices in an automated or partially automated array.
Abstract:
Apparatus and methods are disclosed for treating a sample by selectively controlling sonic energy and/or selectively controlling the location of the sample relative to the sonic energy.
Abstract:
A batch reaction system for simultaneously conducting reactions in at least two separate reactors (CSTR reactors), is provided wherein the at least two batch reactors, containing mixing means and a fluid inlet, a fluid feed common conduit is present for feed fluid to the reactors, which is connected to the inlet of each reactor of a fluid inlet conduits, and further includes a fluid discharge common conduit which is connected to the outlet of each reactor wherein in each fluid inlet conduit and/or in each fluid outlet conduit a non-return valve is arranged to prevent contamination but can provide simultaneous reactions wherein the reactors can be easily isolated from one another during reaction.
Abstract:
The invention concerns arrays comprising hundreds, thousands, to hundreds of thousands of samples and methods for screening thereof. These methods are useful to optimize, select, and discover compounds, compositions, or conditions that prevent, inhibit, induce, modify, or reverse physical-state transitions, particularly in-vivo physical-state transitions relating to disease causing processes. Such compounds, compositions, or conditions can be exploited to treat (e.g., reverse) or prevent the disease itself, the cause of the disease, or the symptoms of the disease.
Abstract:
In one embodiment a method of mixing fluid is described that comprises providing a vibration comprising a resonant frequency; sympathetically amplifying the vibration in response to the resonant frequency; and modulating the resonant frequency, to cause the amplified vibration to generate turbulent flow in a fluid that influences the likelihood of interaction between a target molecule in the fluid with a probe on a biological probe array.

Abstract:
The inventive apparatus is comprised of a means for producing cavitation in a complex reaction mixture to enhance the yield of the selected reaction product, a means for controlling the temperature of the complex reaction mixture, especially during cavitation, and a means for affecting magnetic separation of paramagnetic beads to which the selected reaction product is attached from the complex reaction mixture. In one embodiment, the compound(s) or molecule(s) is synthesized in situ, and isolated using the inventive apparatus. The apparatus finds use in the fields of solid phase organic synthesis, and for isolation and purification of a selected compound(s) or molecule (s), especially where automation is desired.
Abstract:
Method and apparatus for controlling acoustic treatment of a sample including a liquid. A processing volume in which the sample is acoustically treated may be controlled, e.g., by positioning a suitable element so as to reduce and/or eliminate a headspace size at a sample/gas interface. An interaction between the acoustic energy and the sample may be controlled, e.g., by using a headspace control element positioned at least partially in the sample that helps to reduce splashing or other sample ejection that would otherwise occur.
Abstract:
The sequential production of a library of N different solids, in particular heterogeneous catalysts, where N within a day is an integer of at least 2, is performed by a) producing at least two different sprayable solutions, emulsions and/or dispersions of elements and/or element compounds of the chemical elements present in the catalyst and optionally of dispersions of inorganic support materials, b) continuously metering the at least two different solutions, emulsions and/or dispersions in a predefined ratio into a mixing apparatus in which the solutions, emulsions and/or dispersions are homogeneously mixed, c) continuously drying the mixture removed from the mixing apparatus and recovering the dried mixture, d) changing the ratios in step b) and repeating steps b), c) and d) (N−1) times until N different dried mixtures are obtained, e) optionally shaping and optionally calcining the mixtures to give the solids.
Abstract:
A method of mixing (10), including: providing a fluid (10) in a well (6) so as to establish an acoustic field gradient; and applying an acoustic signal to cause mixing within a fluid (3).
