Abstract
A filtration assembly (10) for use in collecting a fluid sample possibly containing microorganisms, and capturing the microorganisms of interest in the sample such that the captured microorganisms can be subsequently detected. The filtration assembly includes a sample reservoir (20) for collecting and holding the fluid sample to be filtered, a fluid port (38) and a vent (70) in communication with the sample reservoir, a filter element (45) disposed in a flow path between the sample reservoir and fluid port, and a cover member (50) detachably covering the sample reservoir.
Claims15
A filtration assembly comprising:
- a sample reservoir for holding a fluid sample to be filtered;
- a cover member detachably covering the sample reservoir with a fluid-tight fit;
- at least one vent in communication with the sample reservoir, wherein the vent includes a liquophobic element that allows air into the sample reservoir but prevents the passage of microorganisms into the sample reservoir;
- a fluid port in fluid communication with the sample reservoir;
- a filter element disposed in a flow path between the sample reservoir and the fluid port.
A filtration assembly comprising:
- a sample reservoir for holding a fluid sample to be filtered;
- a base detachably mounted to the sample reservoir including a fluid port in communication with the sample reservoir, the base including a filter support surface for supporting a filter element;
- a cover member detachably covering the sample reservoir with a fluid-tight fit, wherein the cover member includes a vent communicating with the sample reservoir, the vent comprising a liquophobic element that allows air into the sample reservoir and prevents the passage of microorganisms into the sample reservoir.
A method of filtering a fluid comprising:
- collecting a fluid to be filtered in a sample reservoir;
- connecting a detachable cover member to the sample reservoir;
- drawing the fluid to be filtered through a filter element disposed adjacent the sample reservoir and passing air into the reservoir through a vent;
- and
- removing the fluid which has passed through the filter element from a fluid port.
A method of filtering a fluid comprising:
- collecting a microorganism-containing fluid to be filtered in a sample reservoir;
- connecting a detachable cover member to the sample reservoir;
- drawing the fluid to be filtered through a microorganism-capturing filter medium disposed adjacent the sample reservoir while drawing air into the sample reservoir through a vent;
- removing the fluid which has passed through the filter element from a fluid port communicating with the sample reservoir;
- and, incubating the microorganisms captured by the filter medium.
A method of using a filtration assembly comprising:
- placing a base of a filtration assembly on a vacuum manifold with a skirt of the base contacting an inlet tube of the manifold around a periphery of the skirt, wherein the filtration assembly further comprises a vent;
- applying suction to the interior of the inlet tube to draw a fluid to be filtered through a filter element within the filtration assembly and into the manifold and to draw air through the vent into the filtration assembly.
