Filed:

Feb 28, 2011

Appl. No.:

13/036146

Inventors:

Claude R. Mallet - Attleboro MA, US

Assignee:

Waters Technologies Corporation - Milford MA

International Classification:

B01D 15/20
B01D 15/22

US Classification:

210661, 210656, 210679

Abstract:

Embodiment of the present invention features a device, method and kit for performing one or more processing steps on a sample. The device includes a housing and a processing component. The housing has a first vessel connector for receiving a first vessel and a second vessel connector for receiving a second vessel, and a passage, to provide fluid communication between the first and second vessels. The processing component is in fluid communication with the passage and for effecting a change in a fluid moving from the first vessel to the second vessel through the passage via centrifugal force.

Appl. No.:

11/288589

Inventors:

Claude Mallet - Attleboro MA, US

Assignee:

WATERS INVESTMENTS LIMITED - New Castle DE

International Classification:

B01J 19/00

US Classification:

422130000

Abstract:

Embodiments of the present invention are directed to an apparatus and method for performing parallel processes. One embodiment of the present invention is directed to an apparatus for performing a process having a plurality of steps in which each step is performed in a vessel by flowing a fluid through said vessel. The steps of the process comprise at least a first step and at least one subsequent step. At least one of the subsequent steps is a final step, and each step has a time associated with its performance, a step period. At least one step has a longest step period, and the total number of steps, times the longest step period equals a process period. The apparatus comprises a plurality of vessels. Each of the plurality of vessels is for performing sequentially all the steps of the process in the process period and each of the plurality of vessels is for performing each step of the process in the longest step period.
