Problems solved by technology

These devices increase the complexity and length of operation, as well as the need for trained personnel to perform the analysis, leading to increased costs
In addition, some of the devices require the sample to be transferred from one location or receiver to another one or more times, such transfers increase the risk of sample contamination by microorganisms that were not present in the original sample

Embodiment

[0104] 1. A device for collecting and concentrating a sample for microbiological analysis, said device comprising:

[0105] a piston sized to obtain a substantially water-tight fit within the body;

[0106] A removable support configured to position the microporous membrane in a flow channel, the support comprising:

[0107] porous support structure; and

[0108] emissions; and

[0109] main body,

[0110] which includes the chamber wall; and

[0111] a base configured for attachment to the removable support;

[0112] wherein the body, the surface of the porous support structure, and the vent define a flow channel for a liquid sample;

[0113] wherein the device is configured to hold a predetermined volume of liquid sample; and

[0114] Wherein the predetermined volume is defined at least in part by the movable support configured to position the microporous membrane in the flow channel.

Abstract

The present invention refers to manual devices for the collecting and concentrating liquid samples for microbiological analysis and their respective methods of use. The manual devices comprise a body which contains a sample, a removable support, a microporous membrane, and a plunger. The present invention is also directed to methods of collecting and concentrating of liquid samples onto a microporous membrane for microbiological analysis.

Description

[0001] Cross references to related patent applications [0002] This application claims priority to each of US Provisional Patent Application Nos. 60 / 941,145 and 60 / 941,150, filed May 31, 2007, each of which is incorporated herein by reference in its entirety. Background technique [0003] In several countries, the quality of drinking water for humans is determined by parameters set out in the form of regulations or standards that define (for example) acceptable limits for contaminants of organic and biological material in order for the water to be considered potable Water (i.e. fit for human consumption). Microbiological criteria, of which the determination of the presence or absence of E. coli is the basic analysis, determine the sanitary quality of water for various purposes. In some countries, the quality of human food is additionally regulated by norms or standards that define acceptable limits for microbial contaminants such as total aerobic bacteria, E. coli, yeast, a...
