Abstract: A self-cleaning system for delivering sanitized water to a workstation has a boiler which produces heat-sanitized water and steam. A diverter valve permits a fluid delivery line of the system to convey either sanitized water or steam to a workstation. The steam serves to sanitize the delivery line and workstation and removes biofilms therefrom.

Abstract: Methods, devices and apparatus are disclosed for carrying out multiple chemical reactions, such as in situ synthesis of polynucleotides, on a surface comprising an array of discrete sites. Molecules are deposited at a predetermined number of the discrete sites on the surface for reaction at the discrete sites. The surface is positioned relative to an outlet of a fluid ejection device, which is activated to dispense a small volume of a fluid through the outlet to the surface to provide uniform coating of a continuous region of the surface comprising a multiple of the discrete sites. The fluid is dispensed as uniform particles having a diameter such that the uniform particles form a sheet to coat the continuous region of the surface. In one embodiment of the present invention, liquid is dispensed as uniform particles through a fluid ejection device activated by means of ultrasonic energy. The invention has particular application to the in situ synthesis of polynucleotides in arrays on a surface.

Abstract: A quench zone mixing apparatus that occupies a low vertical height and has an improved mixing efficiency and fluid distribution across the catalyst surface includes a swirl chamber, a rough distribution network, and a distribution apparatus. In the swirl chamber, reactant fluid from a catalyst bed above is thoroughly mixed with a quench fluid by a swirling action. The mixed fluids exit the swirl chamber through an aperture to the rough distribution system where the fluids are radially distributed outward across the vessel to the distribution apparatus. The distribution apparatus includes a plate with a number of bubble caps and associated drip trays that multiply the liquid drip stream from the bubble caps to further symmetrically distribute the fluids across the catalyst surface. Alternatively, deflector baffles may be associated with the bubble caps to provide a wider and more uniform liquid distribution below the plate. The distribution apparatus can be used in the reaction vessel without the swirl chamber and rough distribution system, e.g., at the top of a vessel.

Abstract: A tubular reactor characterized by having short static mixing elements separated by coalescing zones is used to conduct multiphase liquid/liquid reactions. Small droplets of one of the phases are dispersed into the other phase by the static mixing elements. These droplets coalesce and at least partially phase separate as the mixture passes through the subsequent coalescing zone. The tubular reactor is particularly suitable for nitrating organic compounds while forming low levels of improperly nitrated by-products and low levels of nitrophenolics.
