Patent number: 8007743Abstract: A laboratory device design particularly for a multiplate format that includes a manifold wherein the position of the plate is not a function of gasket compression or vacuum rate applied. In one embodiment, the device has a modular design, wherein one or more removable inserts, preferably with different functionalities can be positioned between a base component and a collar component. The particular insert(s) chosen depend on the desired sample preparation or assay to be carried out. The insert(s) are stacked and are positioned between the base and collar as a unit, so that the stack within the manifold does not move during evacuation of the vacuum chamber. The consistent position of the insert(s) facilitates using vacuum sample processing with automated liquid handlers.Type: GrantFiled: September 14, 2009Date of Patent: August 30, 2011Assignee: Millipore CorporationInventors: Phil Clark, Kurt E. Greenizen, John Doyle

Patent number: 7989214Abstract: A microreactor includes a shell structure (2, 3), having a bottom wall (2) and a peripheral wall (3); a layer (5), accommodated in the shell structure (2, 3) and having cavities (9, 10) formed therein, the cavities being accessible form outside the shell structure (2, 3); reagents (17), arranged between the bottom wall (2) and the layer (5), at locations corresponding to the cavities (9, 10). The layer (5) is made of a meltable material that is solid at room temperature, has a melting point (TMP) lower than a maximum operative temperature (TMAX) required by reactions performable through the microreactor (1) and is not miscible with water. The melting point (TMP) may be between 50° C. and 70° C. In one embodiment, the melting point (TMP) is lower than a minimum operative temperature (TMIN) required by reactions performable through the microreactor (1).Type: GrantFiled: December 28, 2009Date of Patent: August 2, 2011Assignee: STMicroelectronics S.r.l.Inventors: Marco Angelo Bianchessi, Alessandro Cocci
