Concentrator device and method of concentrating a liquid sample

Patent image
AECBC

A concentrator device and method of concentrating a liquid sample may be provided. The concentrator device may include a pressure vessel and a filter element disposed within the pressure vessel. The pressure vessel may include an inlet configured to introduce pressurized air into a first portion of the pressure vessel and a first outlet fluidly coupled with a second portion of the pressure vessel. The first outlet may be adapted to be selectively opened and closed. A second outlet may be configured to receive a capillary tube inserted into the first portion of the pressure vessel. The filter element may be configured to receive a liquid sample to be concentrated. The filter element may substantially separate the first portion of the pressure vessel from the second portion of the pressure vessel and may define a retentate side adjacent to the first portion and a filtrate side adjacent to the second portion. When pressurized air is introduced through the inlet and the first outlet is open, a filtrate of the liquid sample received in the filter element may pass from the retentate side to the filtrate side such that a concentrated retentate of the liquid sample remains on the retentate side. When the first outlet is closed, the concentrated retentate of the liquid sample may be forced out through the capillary tube.
