Abstract:
Various embodiments of a light detection device (10) and a system (2) that utilizes such device (10) are disclosed. In one or more embodiments, the light detection device (10) includes a housing (12) that includes a port (20) disposed in a top surface (14), a receptacle (30) disposed within the housing (12) and adapted to receive a sample (80), a detector (40) disposed within the housing (12) along an optical axis (31) and including an input surface (42) having an active area, and a reflector (50) disposed within the housing (12) along the optical axis (31) between the receptacle (30) and the input surface (42) of the detector (40). The reflector (50) includes an input aperture (56) disposed adjacent the receptacle (30), an output aperture (58) disposed adjacent the input surface (42) of the detector (40), and a reflective surface (51) that extends between the input aperture (56) and the output aperture (58).
Abstract:
Various embodiments of a light detection device and a method of using such device are disclosed. In one or more embodiments, the light detection device can include a housing including a top surface and a bottom surface, where the housing extends along a housing axis between the top surface and the bottom surface; and a support member connected to the housing and adapted to be selectively moved from a closed position to an open position. The support member is further adapted to maintain the light detection device in an upright position when the bottom surface and the support member are in contact with a working surface and the support member is in the open position.
Abstract:
A first method comprises using an imaging device to produce a plurality of images of a culture device, analyzing a first image to identify a microorganism colony at a first location, analyzing a second image to identify a gas bubble at a second location, and determining whether the first location is proximate the second location. A second method comprises analyzing an image of a culture device to detect gas bubbles and classifying the gas bubbles according to a size parameter associated with each of the gas bubbles. A third method comprises analyzing a first area of an image of a culture device to detect a first number of gas bubbles, analyzing a second area of the image to detect a second number of gas bubbles, and comparing the first number of gas bubbles to the second number of gas bubbles.
Abstract:
A method of identifying microbial colonies in a culture device is provided. The method comprises using an imaging device to produce a first image of a thin film culture device while providing illumination to a front side of the device and to produce a second image of the thin film culture device while providing illumination to a back side of the device. The method further comprises analyzing the first and second images to identify microorganism colonies in each image, analyzing the first and second images values of a size parameter for a colony at a particular location in the culture device, and comparing the values. The method can be used to differentiate and count at least two colony types.
Abstract:
This disclosure is directed to information management techniques that may be used during automated processing of biological growth media. In one embodiment, a method comprises reading one or more identification elements of a biological growth medium, identifying manufacturing information related to the biological growth medium based on the one or more identification elements of the biological growth medium, identifying sample information related to a sample being tested by the biological growth medium based on the one or more identification elements of the biological growth medium, generating one or more images of the biological growth medium, counting biological agents formed on the biological growth medium based on the one or more images, wherein counting the biological agents comprises generating a count value, and associating the manufacturing information, the sample information and the count value with the one or more identification elements of the biological growth medium.
