Abstract: An improved, lower cost, optical fiber interconnect device of the type known as a “perfect shuffle” and processes for the preparation thereof. The present invention relates to devices that are smaller in size than prior art devices and that exhibit superior optical properties including lower attenuation loss (lower insertion loss) and to processes which produce such devices.

Abstract: The present invention features a vessel for isolating a target in a sample. The vessel includes at least one reaction chamber, a wash system and an effluent system. The reaction chamber includes a closed cell adapted to receive a support, a sample potentially containing target and at least one first probe, and thereafter being closed. The probe is capable of associating with the support and the target to form a support-probe-target complex and sample debris upon imposition of probe binding conditions within the reaction chamber. A wash system is capable of introducing solutions into the reaction chamber for washing the support to solubilize and suspend sample debris. Upon imposition of wash conditions, solutions are allowed to enter the reaction chamber to solubilize such sample debris. An Effluent system is in communication with the reaction chamber and capable of receiving sample debris and wash solutions.

Abstract: Disclosed herein is a fluid handling assembly comprising a multi-valve assembly, a probe connected to a first valve structure in said multi-valve assembly, a plurality of secondary fluid sources connected to secondary valve in said multi-valve assembly and a pump connected to said multi-valve assembly. Each of the valves in the multi-valve assembly comprise valve seats, flexible diaphragms coacting with the valve seat to form leak-tight chambers containing orifices connecting the various channels in the valves, and a means to move the diaphragm to close off the connection between the orifices and thereby shut the valve.
